Greetings All.

Been talking to some friends, and they have suggested to cut out the front resonators, exchange it for just pipeing and to repace my end muffler with a Lukey LR-2779 Hi-Flow.

What do you guys thing performance and sound wise? Anyone done it? How much do you think i could get it done for?

Cheers,
--Tonba

I think Ralliart_Boy did something similar and his car sounds great. At lower revs it's more muffled, but once the revs start to build it bellows a deep sound which is awesome.

Performance wise, I don't think it did too much for his car (although it is already a Ralliart) but maybe you can ask him.

Cheers.

I've got the bolt-on version of the LR2779, the AL4-5711. I know, it's little different but still a straight-through muffler.

I've had it for a while now and am very happy with it. It is very quite while idling (hardly noticable), but once you open up it really roars and sounds terrific. It's at it's loadest between 2000 rpm and 2500 rpm.

Performance wise, I have noticed that it does go a bit harder when you hit about 60 or 70km/h.
Nothing really low-range.

I paid about $175 for mine including installation and I got a tip as well which was extra.

Hope this helps. :D

If you get the muffler done and get a K&N high flow panel filter fitted as well then it noticeably gains power something along the lines of 10KW or so. and you feel it once your car has retrained the ECU to the greater airflows in and out. I have just a universal Lukey ultraflow noticeably louder then the LR2779 but does the same thing as far as performance is concerned. it cost me $130 fully installed including a 3 inch chrome tip. and the filter got for $110 by doing a bulk order with other magna guys.

Well, my bolt on Lukey Ultraflow cost $150 and I fitted it myself. Currently doesn't have a tip, it looks nice and modest. It has a tendancy to drone around the 1800 mark but only if I'm in two higher a gear. It's nice and quiet at idle and has a nice note when it's let loose. It has gotten louder since I bought it and I don't like that. It and a panel filter increased the power by around 11 HP at the wheels which is definately noticeable mid to top end.

Don't know if removing the resonator or hot dog is a smart move. I'd imagine it would make it a bit droney.

I got the LR 2779 for about $220 (welded). Took an hour or so. Plus a $50 tip. Nothing ricey. Just a chromy, rolled end 2.5" tip. Kinda wished I got the bolt on, so IF I sold the car I could rip it off, put the old one back on and put the new one my new VRX :D

Nice and quiet when stationery - great for listening to music at the lights, great when you open her up.

Yep, i have the AL4-5711.

I was initially disappointed as i thought it would be louder than it is.

But, after getting used to it, i am very happy with it.

It sounds standard down low but really growls up high.

I think i can feel a difference in performance which is why i have left it on and not gone back to standard exhaust.

I didnt cut out any resonators and mufflers (and there are lots of them) as Tonba wants to do. I have done this with other cars and the result is terrible. Don't do it. You get a horrible sound from the exhaust, lots of droning and worse performance. Just bolt-on the AL4-5711 and enjoy it.

Whats this about resetting the ECU to get the best results ??

Greetings All.

Wow. Thanks for the fast replys guys! :D
At the moment ive heard many good comments about the AL4-5711 & LR-2779 + cutting out the front muffler/resonators, and also very bad...hmmmmm :doubt:

Whats this about resetting the ECU to get the best results ??
Well, if you reset the ECU, it wipes the memory and starts learning from scratch. And instead of thinking it still has stock parts, it realises it has mild upgrades and adjusts to suit. Hence more power, more performance and better fuel economy. :D

Looking Forward To more Thoughts On This,

I,ve got the bolt on lukey one.Its easy to do yourself.Its an ok muffler.
To be honest its pretty ****,and being a sheetmetal worker I can tell you it is not very good quality.But it does the job,it sounds ok bit too quiet for me(i dont know why everyone on here likes pussy quiet ones)but it is legal at least.
I m gonna take it off a cut down the stock one and weld a stainless turbo muffler of some sort on there.There r hundreds to choose from.
As far as the resonators go I wouldnt bother just get a high flow cat and muffler. :) ??

The reason I'm thinking of chopping out the resonators, is ive heard that if you get the lukey, its got more....'grunt'.... if ya chop out the resonators...

I say leave the resinator in, as Ive driven a 3.5 with cat bacl exhaust with just rear muffler no resonator, and down low it sounded alright, but up higher in the revs it sounded quite bad, not a nice growl at all. And don't waste the money on a high flow cat until your pumping out 200kw's+.

resonators dont effect performance AT ALL! they are soley there to smooth out vibrations in the exhaust gases which effects the sound. if anything with upgrading to a high flow muffler i would consider adding another resonator tuned to a higher frequency which should actually give you a smoother tougher sounding growl as apposed to a whine. i also spoke to an exhaust guy i know and he agreed with pom1. he reckons every since lukey got taken over by walker their build quality dropped. it may not effect performance but he showed me a lukey and a redback and the feel and sound of them (being dropped on concrete) was very noticeable. the redback felt very solid and when dropped gave a quiet thud, but the lukey seemed rather flimsy and gave a loud tinny ding when it hit the ground. in the end its up to the individual but id go the redback, with resonator.

resonators dont effect performance AT ALL!
Wonna bet? it creates a sortof anti venturi effect. and any diameter change in piping weither to big or small makes the flow of fluids less laminer therefor causing restrictions.

a resinator adds two change in diamaters to your system. sure its not noticable in some cases but i others it is. specialy when u have a dyno to check it.

ps i dont have a resinator

You also don't have a cat or the engine capacity required to actually need a 2 and 1/2 inch mandrel bent system with a 3 inch muffler :badgrin: .

No you have a charade .... lol

You also don't have a cat or the engine capacity required to actually need a 2 and 1/2 inch mandrel bent system with a 3 inch muffler :badgrin: .
Yer its stupid crazy loud but it certainly isn't hurting, new custom dump going on soon too its going to be 2 and a 1/4 piping.

and TooSlow... :P

oh and josh, i have two catalitic converters, i dont know what ur on about...


so what if they are sitting under the house :)

you said it yourself charade, its very loud without resinator. so tonba if u want your car defectably loud and vibrating chop em out, or u can get higher flowing "hot dog" resinators those are loud and sporty sounding.
i did up a ford V8 with a twin system that finished just in front of the rear wheels, there were no resinators because it had 2 mufflers and these were much further forward than the back of the car, like not much further back than the resinatotrs would normally be, also each pipe had only 1/2 the gases passing. it was louder than stock (single sytem with 3 resionator and mufflers) but sounded really good, not too loud, very deep rumble and performed graet. but a single system with only 1 muuffler right at the end like u planning will be too loud imo :cool: .

I was planning a dual resinator system with a two inch muffler, it would be quite quiet and flow good for a 1L engine. Only problem was the price and i ended up getting mine as it is atm cos the price was right

So does anyone on these forums actually have the proper cut'n'weld "LR2779" as is shown here in the documents found HERE (http://members.westnet.com.au/akko81/Magna_Specific_Lukey_Exhaust_Parts.zip) and experienced good gains - what other mods do you have???

Does anyone have any dyno b&a graphs of the performance gains their vehicle recieved from fitment of one of these particualr mufflers at all, or will I be the first to post such information when I eventually have mine fitted?

Note: Technical information about the AL4-5711 & AL4-5597 can also be found in the above zip file to which I have provided a link - Hope this helps!

As for resetting the ECU to take full advantage of the new flowed exhaust system I'll simply post this from the manufacturer themselves:

Not really the first. Here's mine that I posted ages ago. Thing is it's not the identical muffler. It's the bolt on replacement which is shorter than the LR one. This one is the AL4 or something like that.

http://www.geocities.com/redavsmagna/current/dyno_20030726.jpg

/Edit: Redav's Link now fixed.

Some nice gains there, hope the actual LR2779 will produce similar results when fitted!

Do you have extrators fitted currently? (Pacemaker etc)

the resonator will give a slight performance lag (according to T-charades reasoning), but only very slightly and not one of us would be able to pick the difference using the bum in back of seat meter! a dyno might show up a little difference but it will be close to SFA!!

Tonba, my mate had a Redback on his TF and it droned away annoyingly at 2000rpm! i waited for the LR2779 expecting a drone but it doesn't at all!! just a nice note.... you can tell why when you compare side by side, the LR2779 is a huge muffler!! the mechanic putting it on said (it was his first sighting of it, they came out the week before :D ) "jesus, look at the size of this thing!!! I hope you didn't want any increase in noise, i reckon it will get quieter!"......... it isn't, but i doesn't drone like the redback...

as for performance, they are both straight through mufflers so they should be very close in that department!

So does anyone on these forums actually have the proper cut'n'weld "LR2779" as is shown here in this document: http://www.fastmagna.com/products/walker/releasedoc.pdf ???

i do have the stainless big LR2779, a lot of others here do as well. didnt get a b4 and after dyno tho. Also i had the section of pipe going overthe rear suspension changed that was 2.25 in, so now its all 2.5 inch. the gain was immediately noticable, seat of pants dyno says about 10 hp :cool:

I've got the LR2779, love the sound, especially now.

How do you tell if your car has a "radio security code"?? (if the car is second hand)

Thanks for the above info akko. I myself am just about to get the LR2779 installed and was wondering if I should reset the ECU so now that I know i should is this, the manufacturer notes, the best way to go about it or is there another procedure people now off or have tryed for 3rd gen magnas.

On the Lukey website there is no mention of the AL4-5711 being Magna specific, It lists only the AL4-5597 & LR2779 units for the Magna...

Does anyone have the AL4-5597 that can comment on it's performance gains when fitted?

The AL4-5597 is a sports rear section only - It bolts up over the rear axle beam to a three bolt flange. The LR2779 has no pipe work on it at all (obviously), as it is a muffler, the same one used in the AL4-5597 in fact. The AL4-5711 is also a rear section only, it also uses a ultra flo muffler.

I got the AL4-5597, a higher-flow hotdog and a tip today.

I can't give specific information about actual numbers increase in performance. However, I think the car revs smoother and more easily now.

It's also frigging loud. I thought it would be a soft-ish growl like everyone was talking about, but it sounds pretty loud to me (maybe I have low tolerance to loud sounds), although the volume may very well be to do with the new resonator.

Also i had the section of pipe going overthe rear suspension changed that was 2.25 in, so now its all 2.5 inch. the gain was immediately noticable, seat of pants dyno says about 10 hp :cool:
Is this the same for all third gen magna's? Seems a bit odd that mitsubishi would make a 2.5" system the whole way through and then drop it to 2.25 just for a small section?? :confused:

So, apart from replacing 2.25 piping with 2.5 piping, did you change it in any other way, i.e. does the exhaust still follow the same path or did you have route the exhaust another way? :confused:

I got the AL4-5597, a higher-flow hotdog and a tip today.How much did your AL4-5597 cost including installation and does the muffler in your AL4-5597 have any identifying marks on it indicating that it is indeed a LR2779?

Obviously the higher-flow hotdog cat & resonator you got were seperate items to the AL4-5597?

/Edit: Redav's Link now fixed.

What was wrong with the link? I pasted it directly from my site :doubt:

No headers. It was a before and after comparing paper filter / stock muffler against the K&N panel filter and the Lukey muffler. That's on a manual 3.0l.


[font=Arial]Does anyone have the AL4-5597 that can comment on it's performance gains when fitted?
Yeah, that's the one I've got.

I'd love to see photos of the various mufflers. I'll take a pic of mine when it comes off. I'm going to try a different muffler as I find this one a bit loud in traffic and on warm days. Sounds great when I'm giving it a bit on purpose. There's a slight about of drone / resonance around the 1800-2000 rpm mark but only if I'm putting my foot down in a gear that's too high for doing that.

In that case Redav, people with extractors (like me) should expect some especially nice gains then when fitting one of these(?) as it should hopefully unleash at little more of it's potential flowing better from front <---> back... *fingers crossed*

Still tossing up whether to get the whole back 2.5" section (AL4-5597) or just the muffler (LR2779). Decisions, decisions...

Well I guess i'll just have to see when I take my car into the local exhaust shop next, I'm getting them to look at my current muffler etc and tell me what it is currently and if they are straight through etc. The dealer I bought the car from apparently fitted a "sports" exhaust to it before I bought it but i'm not so sure - I suspect the tip has been changed and possibly the muffler but I'll let the experts tell me that and make my decision from there.

I might even see if my local exhaust shop has one of each of the LR2779 & AL4-5597s in stock and visually compare the two before I get either one fitted.

If it is true what the Tenneco (Lukey / Walker) rep said about the LR2779 being the muffler used in the AL4-5597 then I'll go that later because it's a bolt on, should take far less time to install and I can remove it from the car later if I ever sell it!

The reason I doubt this information is because the rep said the LR2779 was an "ultra-flo" muffler when according to their website it clearly is one of the "Race" series mufflers.

I'd see if the exhaust bloke is happy to get the two in to check them out. I'm sure they would sell the other one shortly.

So, is your exhaust stock at the moment? If so, the muffler is the main restriction. If you're thinking about the size, there's a guy on the Mogwa forum who fitted the old 3' TT exhaust and with almost identical mods as Manuals car, (- oversized TB + flowed TB - race spec headers), pulled the same amount of power and a curve that was almost identical. That indicates that there could be a minimal loss of torque and with a larger exhaust. Take note he's got a GReddy. I think he's now going to fit the new headers so it should be an interesting result.

I'd just swap the muffler for the moment and if you're happy then great, you haven't spent more money than you wanted and we can sit back and see what the other guy gets.

Size isn't so much an issue for me, just aslong as it flows well (with as little restriction possible), hence why i'm also looking at possibly replacing my cat with a hi-flow unit for the hell of it aswell - I hate large droney exhaust systems!!!

Looking at your dyno-chart you got gains throughout the rpm/speed range, i'll be happy if I can achieve similar gains, the last thing I want is to sacrifice any torque (especially low down) with my Auto box! :D

The 3.5L TJ's like mine have 2.5"exhaust standard anyways I thought, so fitting the AL4-5597 wouldn't be increasing the pipe size any on my car, unless because of the way in which the bends in the standard system are produced it is slightly smaller than 2.5" in places in the rear section as Altera98 said...

Thanks for the above info akko. I myself am just about to get the LR2779 installed and was wondering if I should reset the ECU so now that I know i should is this, the manufacturer notes, the best way to go about it or is there another procedure people now off or have tryed for 3rd gen magnas.
The manufacturers note seem good (anyone else care to comment on this, Mitsiman?), other people I know recommend simply disconnecting the battery, then the next time you go for a drive plant your foot to the floor for a while... *shrug*

How do you tell if your car has a "radio security code"?? (if the car is second hand)
If your car is a TJ and still has the factory headunit (CD player) in it then it will have a radio security code.

How much did your AL4-5597 cost including installation and does the muffler in your AL4-5597 have any identifying marks on it indicating that it is indeed a LR2779?

Obviously the higher-flow hotdog cat & resonator you got were seperate items to the AL4-5597?

The higher-flow hotdog is the resonator (centre muffler). So far I've only gotten this done and the k&n panel filter so I didn't think I needed a higher-flow cat. I only changed the resonator because there was a crack in it. Yes, it was a seperate item.

Anyway, I think the main difference between the AL4-5597 and the LR2779 is that it is a direct bolt-on to the 3.0L Magna, while the LR2779 needs to the welded on.

The whole job cost me this:
1) AL4-5597 = $170
2) Higher-flow Hotdog (Resonator) = $60
3) Chrome Tip = $15

Pretty good prices I think, although the Lukey probably could have been another $10-20 cheaper. The total looked good so I didn't complain.

Just some clarification on the AL4-5711 from Lukey, it is their sports rear section for all TR/TS model Magnas and incorporates an offset/offset ultra flow muffler. :D

will it fit onto a get 1 ?
WTF? :confused:

will the lukey muffler (originaly the thread topic) fit on a gen 1

will the lukey muffler (originaly the thread topic) fit on a gen 1
I can't see why it shouldn't - The LR2779 has no pipe work at all, not even nipple tubes so I gather if your piping could be changed to suit it's 2.5" diameter then yes it should fit with a bit of welding. :D

Not sure how it would impact performance on a Gen 1 though

it'll be a 2 inch system and then just stepped up to 2.5 at the rear for the muffler. no ressy with extractors and i hope its as quiet as all the rest of them with. sleeper TM :D

I have a 2.6L TR and I have the Lukey LR2779 muffler, noticed a nice little gain and sounded a lot more alive even though at low speeds and revs it sounds stock. At first it sounded not much different, then after about 2 weeks it seemed a fair bit better and the car seemed to have a little more guts 2 weeks after I got it for some reason, as if it needed to be worn in almost.

Did you take measures to make your ECU re-learn after installation of the muffler? sometimes it will take the ECU a little while to pick up on any breathing mods that have been done.

It sounded like stock at low revs? Hmm, either i've got a dodgy one or you may have a hearing problem. Mine is louder then the stock muffler, but i was hearing this with the window down.

I got a Lukey and K&N at the same time.

Did a 500km trip the next day only noticing the nicer, but not much louder, note.
After doing the 500km return trip a week later the car felt much more responsive up over 3000rpm.

I feel it's not quite so good down low but that may be subjective due to the improved high range gains.

Last year I put a 2.5" mandrel bent pipe on my V8 Land Rover from the extractors back with one tiny resonator at the end. It's SO bloody loud. When at full bore going up soft sandy tracks you can hear her for MILES. Sounds awesome at low revs as well but I would NEVER do that in an everyday car. 19 year old Landy's with huge tyres aren't quiet any way so the loud exhaust doesn't get noticed. Besides, V8's don't produce noise. It's called music!

In the Magna this type of setup would be intolerable.

i think u could modify a bit there without spending too much, V8's with twin system with only a single small muffler/resinator on each side sound sooo sweet and not too loud, also perform beut. i did this on a V8 fairlane i had, twin system exiting just in front of rear wheels with a small muffler on each side. it had a very deep sweet rumble that when i pulled up outside anyones house u would always see some curtains move so they check out whos coming, but not loud to drive at all. it also allowed it to rev right out. :cool:

Bought the lukey 2779 muffler with piping and was pistoff with the lack off sound.

Bought 2"5 piping from Cat-back RIPPED out the resonator and i ****ing love it.
Doesn't drone in cabit (with windows up)
Windows down you feel safe with the piping and lukey to go any common***** compeditors.

Mates quotes, "Sounds like a turbo"

My other mate put a 2" 3/4 piping from cat-back with performance muffler and took his resonator out also. He has a 93 Subaru Liberty, its louder than mine... drones and makes it sound like an Sti with a 3" mandrel.

All he gets is ****.
All i get is praise.

Do the math.

Genocide,

Doesnt the car have 2.5" piping from the factory ?? If so, why did you replace it ??

Also, what resonator did you remove as their is two, one behind the cat and one near the rear axle or did you remove both ??

Also, how much ??

Greetings All.

Not quite Rallyart Boy. Magnas aparently come with a 2.36" stock pipe size...(dont quote me on it). But it is an unusual size...

Cheers,
--Tonba
++++

Stock piping as quoted by Mitsu is 60.5m which is closer to 2.36' than 2.5' but in reality, it varies a little. Going to 2.5' is larger so will provide a better gain for top end. I doubt there would have been any loss down low. Header design would have a far greater effect on this than overly larger piping.

I popped in to the exhaust shop yesterday. I was looking at a freeer flowing muffler to replace the one I damaged offroading :P Coz I do heaps and heaps of Ks, I don't want any cabin drone. The manager there was saying by increasing to 2.5" all the way through I will get cabin drone :cry: Can anyone confirm or deny this? My zorst is silent at present. Would it be barely perceptible drone, or something that would drive me crazy after a 12 hour day in the car? I don't recall the brand of muffler he quoted - think it was a Walker.

just get the Lukey (LR2779)!!! (its a rear muffler only) i guarantee it will be the best for you!! it is near silent until you open it up, and then its not overpowering... there will be little or no drone!! it gives a small power up (its cousin, lukey make the original Mitsu ones as well, provides the only difference between a 155kW exec and 163kW sports)

Walker and lukey are one and the same (Lukey being the 'performance' brand)...

going to a 2½" piping cat back will give marginally little to improve performance over the stock (60mm pipe, some parts of world use metric these days!!) ... way better off getting extractors!

just get the Lukey (LR2779)!!! (its a rear muffler only) i guarantee it will be the best for you!! it is near silent until you open it up, and then its not overpowering... there will be little or no drone!! it gives a small power up (its cousin, lukey make the original Mitsu ones as well, provides the only difference between a 155kW exec and 163kW sports)

Walker and lukey are one and the same (Lukey being the 'performance' brand)...

Mmmmmm extractors. Quoted me $600 supplied and installed for Pacemakers too. We'll see what the tax return brings!

I popped in to the exhaust shop yesterday. I was looking at a freeer flowing muffler to replace the one I damaged offroading :P Coz I do heaps and heaps of Ks, I don't want any cabin drone. The manager there was saying by increasing to 2.5" all the way through I will get cabin drone :cry: Can anyone confirm or deny this? My zorst is silent at present. Would it be barely perceptible drone, or something that would drive me crazy after a 12 hour day in the car? I don't recall the brand of muffler he quoted - think it was a Walker.

he was right, when i got my lukey LR2779 i got the last section of pipe over the rear suspension which was about 2" replaced with 2.5 to make it 2.5 all the way, and i do have some drone, not all the time, but definitely there on freeway at 100-110. a bit fatser or a bit slower and its gone. but as far as performance mufflers go it definitely does perform noticably and mostly just gives a very nice low growl.

What are you guys paying for ur lukey exhausts? I am confused coz some people on here seem to have paid $270.00 for the lr2779 while others pay $130

just go n buy a dirty great big cannon.... or not have a rear muffler at all just a straight pipe
