Well so it's been a whole month of having a stock Magna, tonight I have just fitted a cat back Redback system for my TL, and can I say WHAT a different car it is now. The dam things spins wheels like crazy and 1to2 she will chirp too no probs. The car is a hell of a lot more responsive and revs out so dam quick in the first 3 gears you swear to god your gona blow something up. When I purchased the exhaust I was told I would need to shorten it to fit the TL as it was designed for a TK-TJ, but it actually bolts straight in no probs. Took about an hour to install, I will take some under pics soon to post but I can highly recommend the unit.

The actual sound is not to loud, just nice and growl down low, and actually quite, quite once above 3000rpm. The only thing is I need to remove about 1cm from the back of the rear bumper as it sits a little tooo close. Other then that for $300 I can HIGHLY recommend it.

Will post pics soon.

Next on the list.
-throttle body
-CAI and filter
-timing
-short shift

i dont have a full redback cat back, i just have a redback rear muffler (not even sure if its the same thats in the cat back system) but i know it made a big difference to my TL, especially in terms of low down responsiveness

Yeah, I have always been happy with mine. Money well spent.

Only annoying part is it does sit too close to the bumper on mine and has melted a part of it... but not badly though. Some people don't like the drone cruising at 2000RPM but I don't think it is bad personally.

Hay has anyone made their CAT convertor straight through. I was thinking of buying a high flow through unit but i can just punch the inside of mine out.

Has anyone got rid of their cat inside. Have you noticed much improvment.

I went and priced a reback cat-back from my local shop.

Apparently there are two pieces to the thing, correct?

And each one is around $300???

For a total of $600???

There is 2 parts.

The muffler and then the piping + hotdog + bends to muffler.

In total it should cost you $300 to buy the lot + around $100 to have it installed.

I have to go back and see my local exhaust shop then.

We both read it as each piece costing $300ish....

YEP i purchased the whole thing for $300 of eBay australia through a company called


Online Performance Autos

sales@onautos.com.au

give him a tingle and have a look, you can also do a search for MAGNA in eBay OZ and it should show him. He askes 380 for them but i only had 300 so that's what i got it for

mine cost 140 fitted, just the muffler. I dont think theres any advantage in the entire catback system as its all 2.5" streight through anyway

I just had a redback muffler installed on my AWD on Friday. Taking it back tomorrow as the drone between 1600-2000 rpm is very painful. Mind you the increase in performance is noticable. Took it for a nice drive on the highway (about 350km's) and the fuel economy was approx. .5 l/100km better than previous trips.

Oh well, can anyone recommend a different muffler that will give the same performance but no drone? Lukey perhaps? Berkley PEX?

Get a hotdog or 2 put on the pipes to stop your drone.

OK I'll bite. What are hotdogs?
Are they basically what you would call a resonator?

HI all, just thought I would update. Got a berkley PEX (don't have the model number on me atm) and the drone is very well controlled to non-existant now. Still sounds very nice and even better the fuel economy is still there :cool:

Looking for the next highest value mod I can perform. Won't hijack thread though :P

I think the autos drone more then the manuals. No problems with mine. LOve it

Does the full redback system include a muffler or would you have to purchase one seperate?

WogsRus
26-07-2005, 03:49 PM
Yep the system I got came with a rear muffler, and centre pipe. The centre pipe has a small muffler and a small resonator.

The RRP of each section is $300 ($600 total). Dad sells them for about $380 fitted for the entire unit. Handy if you're in the Hunter Valley. Tip is extra.

I upgraded to 3" from the cat back into the Berkley PEX and the drone is killing me slowly. I have 2 x 18" resonators as well :confused: Now that Dad's got the muffler shop I'm going to see what options are about to fix this drama.

I'm putting a twin PEX on on Thursday too. Because I can. :D

I am also seriously considering a PROPER twin exhaust system in 2" back to the 2 x 2.5" PEX's.

Will have twin cats, custom tuned length 34" primary headers. Might replace the Oval tips with 2 x twin 2" tips.

Do you think that is mainly due to the 3" piping through to the muffler? It will be interesting to find out what you think of having the twin mufflers, as even though this exhaust is much quieter it can still sound loud (I would say slight drone) under load. What I did not realise was the size of this muffler :shock: It is larger than the stock muffler by a healthy margin and the exhaust shop had to manufacture a new connection from the end of the stock piping to the muffler inlet.

Oh well... on to the next mod.... pm sent :cool:

PM received.

Yeah I went too stupid with 3" I believe. We were too busy to put my car up - the 2nd hoist has a VK commodore with 360ci Dodge getting headers built for it. Everything was going OK until we discovered the motor is mounted 1" to the left in the engine bay :doubt:

Here's a pic of the insides of the stock muffler fyi. Lucky the car can run at all with this sort of back pressure!!

2nd pic is the 360ci headers atm.

I am pretty sure the standard Redback system has a similar 'Z Flow' exhaust setup like that one... I know mine is a Z flow. I don't know for sure but I believe it is basically on the same principle... and some argue that this back pressure is beneficial/necessary...

I tend to feel that Mitsu would have poured much money and time into flow testing on this design and you would hope they got the best results that they could hope to get... maybe that is why they have the dual exit pipes to increase the amount of exhaust exiting... which in fact may be less restrictive then other standard exhausts... i could just be talking out of my rear but I have read up about this before I had mine fitted.

I'm no expert.

When i made a custom exhaust for my manual 3lt, we took the car for a spin with the exhaust removed and only the CAT on. The car was gutless and didn't go anywhere in a hurry. The car went slower with the redback and 2.5" system, compared to the standard system and redback rear muffler. The is a lot faster now the computer was retuned for the new exhaust.

Moral of the story is the car will have more torque and hence more power with less backpressure IF it is tuned properly.

I think the standard muffler is all about noise supression rather than anything to do with flow/performance hence why they changed it for the sports/vrx. Also it is cheap and would last warranty period.

Wouldnt thought it would make that much of a difference but i can see how i guess considering how much airbox restriction there is

With backpressure, alot of backpressure is benificial at low rpm, gives better response down low, but will suffocate your motor at high rpm, the straigh thru pipes will breathe well at high rpm, giving higher peak hp, but might lose a bit of torque down low.

My local exhaust shop is looking into a muffler for me, he was going to sell me a redback muffler, but said it can drone a fair bit, and that he might be able to get a different one with what he called a "balance tube" in it,Reckons it cuts out the drone. dunno what the hell it is, he's gonna call me back if the manufacturer makes a bolt on one formagnas and i'll go check it out.

Hi,
Did anyone have any luck with an exhaust system that won't drone?
I have heard that Mitsubishi changed the rear muffler on the sports/vrx in the TL models to get rid of the drone that the TJ's suffered? Any TL owners confirm? (drove a TJ sports auto and the drone was annoying when cruising!)
I have a TJ auto, so its going to be more prone to drone, so was after something that's nice, but won't done when crusing?
Thanks heaps

i have a full redback system as stated previously and a high flow cat and no drone, it is still very quiet, i wish i could tape it for people so that they would belive me. I think maybe the Autos drone more then manuals because of the way the auto uses it's gears so the motor is always at low rpm. Mine sounds great and goes great. DO IT.

i think also the combination of the redback muffler and the stock center pipe causes droning as the stock pipe has only one resonator the redback system has two smaller ones taking out the low rpm drone.

Hi wilsact

Quote from wilsact:

From Barry:
I have done a lot of testing and, like you said I found the droning from fitting a Lukey sports muffler really intrusive in my TJ2.
The harder you press on the accelerator pedal, the louder the drone.

I found that the solution is to improve the combustion of the fuel. Not only does it remove most of the drone, it also improves the tendancy for acceleration lean-out, especially when Hi-flow air filters are used. I've also noticed an improvement in throttle response.

There is a kit especially for 3rd Gens so if you'd like to try it with a money-back product guarantee just Post or PM for more info

Cheers Barry :cool:


Question to Barry from another AMC member:
Thought about tricking the Oxy sensor to provide slightly richer mixture?

Quote from Barry:
I've looked at the possibilities but if you view the pattern on a LED mixture meter display you'll notice that the Oxygen sensor detects whether lean or rich and then signals the ECU to correct - the result being a quickly reversing display either side of stoichometric.
Any changes in fuel efficiency are soon negated, as the ECU simply "reads" the mixture as being either too rich or too lean.

The best solution by far is to pre-heat the fuel, gain better combustion which means less unburned fuel droplets in the exhaust headers. The Oxygen sensor reads this as being "lean" and richens the mixture. This is how you achieve increased power when the hi flow air filter intakes a high volume of air at lower revs, otherwise causing lean-out.

I noticed this when the tone of my exhaust changed from a 'drone' coming thru the floor, to a sound more like a V6 at the Lukey muffler end, and a little bit 'honda-ish' at the front.

honestly how much gain could u possibly get from a 2 1/2 or 2 1/4 catback on a 3litre N/A?

or even a 3.5

Im new to the whole N/A thing as every car ive had has had at least 1 turbo on it :)
Performance wise the only thing i can see it doing is making it a little more responsive down lower in the rev range... but i see all these posts about people now chipring 1st and 2nd (i assume in a manual) and really think to myself... is this from your now more aggressive driving due to the better sound coming out of the exhaust or from such a power gain that it spins the wheels harder?

i know with our old soarer which was a TT that i drove far more sedately with the stock exhaust on because it was dead quiet compared to when it had the 3.5inch straight pipe exhaust on it which was about 100db at 1200RPM. When i had that on it i used to floor it all the time... but that along with the pod gave the car an extra 15kw at the RW.

So how much can a N/A 3 or 3.5 honestly get from a catback?

2 - 3 kilowatts if your lucky. Its more the whole my car sounds better, so must go better that makes people think it is more powerful. A least, that's the consensus ive come to after reading these forums. If anybody actually knows of any larger benefits, please post up.

This is actually pretty true - any modification that alters the sound of the car is assumed to have made a big difference - whether it has or not... that is only able to be determined on a dyno.

This is where makers of performance air filters win out - plus people don't like to admit (even to themselves) that they may have been duped...

well say what u may but i picked up 8 KW over the stock system. that included the cat. After the CAI and Filter i managed to get another 4.3 KW and with timming a further 3.2kW, i have some dyno printouts but no scanner to get them up.

That is on a Series 1 TL LS. and those figures were at the crank sorry, should have clarified, i can't remember the WHP, i will dig up the prints. Many people say that the stock canter pipe and exhaust are good but when you compare air flow at full throttle for a 2.1/4 pipe and 2.1/2 pipe, it makes about %32 extra flow, and with no cat to allow for restriction, who knows. I certainly know the extra power is there, I can beet many magnas out there, so I don't know maybe my car was built on a Wednesday, LOL.

Hi Guy's,

I want to get one of the Redback systems for my TE, will this be a direct BOLT-ON fit , or will i need to do some welding?

Has anybody fitted them themselvses? was it tricky?

I fitted some RPW extractors a few months ago and it wasn't that hard, so if it's a bolt-on kit them i want to go DIY.

Thanks

WogsRus
19-10-2005, 01:33 PM
not sure if the TE will fit but mine was a direct bolt on, the kit came with new seals, bolts ect. it took me about 1 hour to do and you will need the have the car on a high stand to remove the rear mufler over the rear suspention arms ect.

It's an easy job and i'm sure most people can do it quite easily.

I used a bit of exhaust sealer just to make sure that the seals cealed propely, i know this is not a must but i was being pedantic.

Yeah it's a long post but.....

Magna / Diamante Products.

*** The magna exhaust was initially thought to be a very good system with its 2 1/2" mandrel bent system. Unfortunatly some pretty nasty bends, restrictive cat converter and muffler did not help to produce credible gains in engine mods. RPW has done some research into this and found that credible gains can be found in the vehicle with a decent exhaust system fitted. There are basically three options when coming to the Magna exhaust systems - we will work from the cheapest to the most effective. These recomendations are for naturally aspirated vehicles. For vehicles going turbo, we of course recomend going straight to a 3" or 3 1/2" system.

1. The cheapest and very effective option is to fit the Lukey replacement muffler / complete rear system to the vehicle. This reduces around 70% of the back pressure problems in the vehicle and is highly recomended. Not too noisy is normally worth arund a 10 - 13kw gain at the flywheel over the stock system. Very popular option. For the 3.0 brigade, this is a particularly good option for the smaller motor.

2. The next option is to replace the rear muffler with a bullet / canon style muffler. RPW has stuck with the Lukey Ultra Flow range and has found them to be very well priced, very effective and not too noisy. We actualy recomend using a 2 1/2" muffler on the 3 litre models and a 3" Muffler for the 3.5 units as the larger unit will flow slightly better and at the same time provide much improved noise reduction.

3. The third and best option, also most expensive is to replace the whole system including the cat converter. RPW has found on the 3.5 models that a combination of a high flow 2 1/2" cat converter, 2 1/2" piping mandrel bent with a 2 1/2" spiral flow resonator and 3" Lukey Ultra Flow Muffler provides an awesome deep sound as well as very noticeable gains in power. Independant dyno test of this system over a stock system with the Lukey replacement muffler found a 4hp gain at the top end of horsepower, but found between 30 - 80km gains of 10hp at he wheels with increased torque before flattening out again.

4. The fourth and final option is that RPW has found that upgrading the whole system to a complete 3" system ie 3" cat converter, resonator, muffler and piping mandrel bent whilst does not on a fairly stock motor increase horsepower over the above 2 1/2" system, nor did it lose horsepower or torque. We have found the vehicle to be non - responsive in this size meaning that either sizing works well. The 2 1/2" system tends to be slightly quieter. But if you are planning on doing more work later being camshafts, twin throttle bodies, internal engine work etc then the 3" system is definitly the way to go to bring it in line with future mods. And since there is no loss of power over a 2 1/2" system its the perfect way to go.

I just had a redback muffler installed on my AWD on Friday. Taking it back tomorrow as the drone between 1600-2000 rpm is very painful. Mind you the increase in performance is noticable. Took it for a nice drive on the highway (about 350km's) and the fuel economy was approx. .5 l/100km better than previous trips.

Oh well, can anyone recommend a different muffler that will give the same performance but no drone? Lukey perhaps? Berkley PEX?
Lukey make a virtually exact copy (maybe they manufactured the original?) of the VRX. I put just the rear muffler on mine. Some talk about drone, but I cant even hear a difference!
Quite a few people have commented on how nice it sounds, driving down the street. Nice performance too.

very illegall and dont forget you could be up for a fine of $6000 if found out i had one on my old commodore punched theinners out then welded pipe through the gut was awesome i just took my ressy off about to put a hot dog on i lost backpressure but i agree i have redback muff and standard cat pacie extractors sounds good goes like the clappers

if you want a straight through 'race' cat, dont destroy your current one.

place a flange 'behind' the cat on the existing system, and make a piece of pipe to join the flex pipe to the rest of the system. around this pipe place the heat shielding from the cat. it means if you get caught at least you have a cat to replace it with.

my systems like this. its in 4 sections:


flexpipe --> 'start' of system
real/original cat
'race' cat - pipe, with heat shielding

'start' of system --> behind resonator
resonator
straight through pipe (no resonator obviously)

behind resonator --> flange over axle
straight through, just containing bends

flange over axle --> rear of car
hi-flow muffler
straight through pipe



its not much more to get it done this way, if done properly gasketts used, etc, theyre wont be any leaks, and it gives huge variety, and you can see what you like the sound of best. its easy to move around defects etc.

*EDIT* - just realised how old this thread is :confused:

Yeh the redback systems are nice, i noticed a big difference once installed, i have the full system up to my cat converter, then a custom made High flowed cat converter which just adds to the performance of the redback!!! i have a nice sound when idle, and a nice Growl above 3000rpm. Although i paid a lot more as i had the Custom Cat converter installed with the redback system!!!

But yeh always a good first mod :thumbsup:

I have berklee mufflers and resonator, and its too droney. (its all straight through though).

I will be replacing the rear mufflers with redback i think the guy said. I just hope it won't affect performance too much.

I posted recently about getting a new rear muffler for my tj sport. The exhaust shop put on a berklee rear muffler (twin exit) as in the standard tj, probably beacuase I was complaining about the sick drone coming from the redback straight through rear muffler I had on. I was a bit p****d off that he put such a "restrictive" muffler on without telling me that was what he had planned, but after driving around with it on for the last month, I reckon it was a good move. I notice no real drop in performance, and a definite improvement in throttle response. Better still absolutely no drone (hooray). Car still sounds good when the boot goes in, with a lot more induction noise being noticed, which sounds pretty special on the magna engine anyway. Im sure big/free flowing exhausts on a stock magna engine are not worth the effort in improving power.

I notice no real drop in performance, and a definite improvement in throttle response. Better still absolutely no drone (hooray). Car still sounds good when the boot goes in, with a lot more induction noise being noticed, which sounds pretty special on the magna engine anyway. Im sure big/free flowing exhausts on a stock magna engine are not worth the effort in improving power.

redback systems dont drone.... :confused: maybe your muffler had kicked the bucket?

i dont know what these guys sayin that redback systems dont make any difference are on about.
i had been out our local "legal" drag strip and been beaten by numerous vr-vs commodores.
had my redback fitted, went out that night and beat 2 vr s-packs, 2 vs s-packs and a el falcon v8. best mod i ever did. and throttle response is through the roof. 4 grand is the sweet spot, i love the noise between 1800 and 2000 rpm. best mod i have ever done to any car, not just my 'rada. hihgly reccommend it.
does anyone have views on a set of pacey's $600 drive in drive out? let me know please
cheers.

I have just come back from an exhaust shop(Muffler Mad - Browns Plains) after getting installed a Redback Hotdog and Muffler
i had the Lukey LR 2779 replaced cause it sounded drony and a wet fart sound at certain revs and now.... what a difference, its a great sound, nice and deepish and no droning what i can tell, + a new chrome tip all for $200.
My car already has pacemakers and hi-flow cat and he used the existing 2 1/2 inch piping.
Sound File [[ http://yep.it/?ql5ymw ]] Im very impressed of the sound.

I just had a redback muffler installed on my AWD on Friday. Taking it back tomorrow as the drone between 1600-2000 rpm is very painful. Mind you the increase in performance is noticable. Took it for a nice drive on the highway (about 350km's) and the fuel economy was approx. .5 l/100km better than previous trips.

Oh well, can anyone recommend a different muffler that will give the same performance but no drone? Lukey perhaps? Berkley PEX?

Mostly due to having a long straight exhaust whereas the fwds weave around a bit. Definately NOT the PEX.

The RRP of each Redback system by the book is $300 per piece. Being a magna, many muffler shops think we're stupid enuf to pay it.

Just went to the local Midas workshop looking to price an LR2779.
It was $197 to supply but in the catalogue it had no inlet and outlet pipes so would cost more to fit. I thought they were supposed to be a bolt-on replacement.
They can supply a bolt-on Berklee with twin 2.25 outlet pipes for same price. What is the "PEX" that people refer to when talking about the Berklee earlier in this thread ?
Thanks.

I got a job at the MINE.

I'm guessing PEX is just the name of the Berkley muffler?

Just wondering if everyone or anyone gets rid of the secondary muffler?

I'm after a new muffler for my KJ AWD just to give it a bit more note.
The last thing i want is for it to be loud and droany. From what i have been reading the redback muffler and hot dog looks like the best option like ICE WOrrier has had done on his. That sounds absolutely great by the way mate. Exactly what i am after.

Does anyone have a picture of what they look like on their car? Would be much appreciated.
Don't really want to see it like the stock one.

You wont see anything different unless you ask for a specific style of tip.
