hey boys,

i need some advice, im getting a redback cat back system installed today, but im not sure this redback cat back system will have any improvement over my standard sport system (the straight through muffler design)

i know some people have said they are worth every penny but i think these people have installed them on execs and stuff where the stock system is not straight through and is very restrictive, so they will see a big improvement,

where as i already have a straight through system, the standard one that comes on all Magna Sports models... so does this mean that a readback system will only be replacing what i already have? and that it will just be a waste of money?

does that make sense to you fellas?
any replies appreciated.

Beef

very interested in this as well, really like the sound of the standand system:D

yeah well i just thought of it because the standard 'Sport" system is 2.4 inch in diameter with a straight through muffler.... and the redback is 2.5inch with a straight thorugh muffler...

so i just dont know if its gonna justify spending $450 on something that i pretty much already have... because it doesnt seem like it is going to be any different.

i can understand people getting them installed on execs and other magnas with non straight through systems because that will have some effect, but on sports model magnas the system is already very similiar to what the redback is.

anyway, please have your say, and dont let me spend $450 on something if its not going to have that much of an effect.

Beef

Yeah I dont think the 2.54mm increase from a 2.4 inch to a 2.5 inch is going to do anything performance wise. Some actually say the sports exhaust is a 2.5 anyway - done by lukey.

Better to spend that money on lowering it or putting in slotted front rotors to get it to stop a little faster.

Have you read this? http://www.wermspowke.net/wiki/index.php/Exhaust

I dont know where u got your prices from guys...


I got the Redback system incl. HighFlowcat, 2 1/2 inch piping, high flow hotdog and high floew rear muffler with tips of my choice installed for 600 bucks.
Sound is the best I have heard and performance gain will be tested this weekend at the 1/4 mile..


RedBack rockz!

yeah i understadn, but

what im aksing is:
is there any point going from the standard Sport system on my magna to a Redback? because there seems to be hardley any difference in pipe diameter or end muffler design.

so what do u think?

Beef

Probably a change in note of the exhaust at best, your not going to notice the performance difference

Stock sports exhaust is press bent 2.25" - from what i was told.

The Redback system is 2.5" mandrel bent

Its worth the money if you want a bit more bark. Will you see massive gains? No.
Will you see massive gains on any of the cheaper NA mods? No.

Totally agreed.
But IMO the sound alone is worth it!

Lukey claim all their exhausts are Mandrel, so unless MMAL decided to "de-option" the sports exhaust, it should be Mandrel if its based on the LR2779

Beef, if you get it off, get the guys to have a look at it and let us know.

Lukey made the muffler.. Not the piping that goes with it. (only from what ive been told)


And its press bent as the guys at Daalder cut it open to check it out.

ok so i have decided im not going to go ahead with it, because i dont see the value/performance ratio being that great for my situation, as i already have a 2.4 inch pipe with stright through muffler FROM STOCK... so i think ill pass on the redback....

do you boyz agree?

Thanks Bain, Mitsubishi cuts corners yet again.

Oh well, probably only worth 1kw.

do you boyz agree?

Yep so go and lower it, or get a strut brace, or get slotted rotors with the money you were going to spend on the exhaust.

Are you sure you have 2.4inch?

Thats a very unusual size and stock they have 2.25"

2.4 inch is a wierd size...
Anyway i'm only going to get a sports muffler put on, keep the stock piping, I just want something with abit of an extra growl, but nothing loud, i like my car quiet at cruising speeds.

yes im sure it is that size.
look here.
http://www.wermspowke.net/wiki/index.php/Exhaust

"The stock exhaust (cat back) for 3rd gens (3.5L) is quite good for a standard exhaust system. The standard exhaust piping measures 58mm (2.3") at its smallest diameter on a bend, and 60mm (2.4") along its straight sections."

and mine is a sport so it has a straight through muffler.

you see lads?

Beef

so i dont really see any benefit ni spending $450 to increase pipe diameter by 0.1"

its not a wise move in my opinion.

you think so?

Beef

yes im sure it is that size.

I think you will find thats its incorrect :)

Ive never heard of a 2.4" exhaust system. Usually its 2.25" or 2.5"

Perhaps EZBoy could comment on this as his father? or him or someone owns an Exhaust shop.

*edit* If you think 400 is a waste of money, you better stop modding now :)

OI Bain,

it is a waste of money man because i pretty much already have this system...

so $450 spent on something i pretty much already have is unjustified... am i right?

Not really.

a .25" upgrade will see benefits, but not in the effects of massive. It will also give your car a much more aggresive note (if thats what youre after)

Personally, i would spend my money on handling mods over engine mods for now.

$400 will get you
Spings
Strutbrace

You will get far more enjoyment out of your car not handling like a boat ;)

Bain,

i already got my car lowered last week, Lovell Super lows all round with KYB Shocks.

so i dont need to spend it on that, and i have new wheels, what will a strut brace do? or the other thing im thinkin of is a better sound system, start to get that underway...
what you think abuot that man?

Strutbrace will allow for better cornering. (helps reduce the struts from flexing which reduces the amount of grip/wheel on the group)

Add in some thicker front and rear sway bars aswell - these are cheap to. Then you will have a very well handling car.

Sounds system is nice - if you are into that sort of thing. Personally im more performance orientated and the sound system comes off 2nd best. Although upgrading the stereo itself can be a nice improvement!

Bain,

what is a set of front and rear sway bars gonna cost me man?
and where can i get them?

Beef

Up to around $400 for both - ive seen them as low as $170 each, but thats a few years back.

Speak to any of the suspension specialists in Tas mate. You can also get them from Autobahn, Bursons etc etc.

Phillcom also sell them here on this website, im not sure what sort of discount they give though. If you want me to make a few enquiries here in Melbourne let me know.

*edit: I just checked out the whiteline website.. www.whiteline.com.au/store (http://www.whiteline.com.au/store) they have a store. You can buy the front and rear sway bars for $171.82 (+GST) each

QUOTE=dark_magician]we hav 2 ralliart magna both manual on our dyno day last yr 1 has an aftermarket exhaust system and the other is stocko....stocko runned 180hp@fw=135kw while the other runned 160hp@fw=120kw. i guess not all same kind was built to run d same quality.[/QUOTE]

this was posted in a thread i statrted regarding similar question.....you will be wasting your money in my opinion. spend it on other mods. i am not saying do it and you will lose power etc...this is just an example, but i thought about changing it after having other mods done for little gain....it wouldn't make a difference enough to justify the money

lol Looks like you made a friend Bain:D

In all honesty - I think you will be disappointed in the performance gain you get from fitting this system. As you've said - you already have a straight thru muffler and the standard piping is only a fraction of an inch smaller in diameter than the redback replacement piping. Upgrading the exhaust system from the cat back would only really deliver a worthwhile improvement when your exhaust becomes the biggest restriction on the engine. And with a fairly stock engine, and a straight thru muffler and a few other popular bolt on mods - I'm gonna go out on a limb and say the next most restrictive part of the engine is the cams.

2.4 inch is a wierd size...
Anyway i'm only going to get a sports muffler put on, keep the stock piping, I just want something with abit of an extra growl, but nothing loud, i like my car quiet at cruising speeds.


how much for a rear muffler with a bit of growl... my missus parents want one on thier 04 Solara. and i want one too...
on the subject of stock echausts though.. mine has a bit of a note to it.. now, the dealer that i bought it of claimed that it has extractors, but after looking at it when it was over the bit i found that to be totally bogus... as far as i can tell its a stock exec exhaust with a note.. or is there something else wrong.... could it be a hole or is the cat ****ed?

What do your current exhaust headers look like?

Maybe it has an aftermarket muffler.

Greetings All.

Sorry guys...Just thought you guys were a bit confused with pipe sizes and muffler designs...

Sports/VR-X Pipe Size = 2 3/8" (Press bent)
Sports/VR-X Muffer Design = Offset Inlet/Centre Outlet (NOT Straight though design)

Red Back System Pipe Size = 2 1/2"
Red Back System Muffer Design = Straight through

Performance gains over VR-X/Sports system...next to none unless something more substantial then extractors and pod are done...(ie cams/head work/computer tune/etc.)

Cheers,

The numbers I've got on the wiki are from someone who got under the car and measured their piping. If they're wrong I'd like to know what is right so I can update it.

From what I've heard, the exhaust on the 3L was a 2.25" design, and it stands to reason they'd make that larger for the higher capacity and performance from the 3.5L engine.

Sports/VR-X Pipe Size = 2 3/8" (Press bent)

Just curious - where'd you get your numbers from?


Sports/VR-X Muffer Design = Offset Inlet/Centre Outlet (NOT Straight though design)

If it's not straight through, what is it?

For what it's worth, two people have examined the VR-X/Sports muffler. One says they can see in one end and out the other, following the pipe all the way through, and the other says that's not the case.

VRX's are a tri flow or something, and mines mandral bent and it's 63mm which is 2.48". People think it's a funn size cause it's a mm pipe, being japanese that's what I would expect, has anyone found imperial bolts in there car?

What do your current exhaust headers look like?

Maybe it has an aftermarket muffler.


dunno:nuts:

and it doesnt seem to have an aftermarket muffler.. well atleast not the rear one anyway...

do you have two pipes out of the rear muffler? if there is only one its the mitzi sports muffler and would explain the note:)

If you dont know what your extractors (headers) look like. How can you make the assumption that there the standard Mitsu ones?

For what it's worth, two people have examined the VR-X/Sports muffler. One says they can see in one end and out the other, following the pipe all the way through, and the other says that's not the case.

My TJ Sports (2001) came with a triflow rear where as my Ralliart (2002) came with a straight through rear.. both came from Mitsu this way....

easy test.. get a broom stick and shove it in your muffler... if it goes STRAIGHT in and seems to go nearly to the other end of the muffler (doesnt feel like its catching half way) then its NOT a straight through muffler, its a triflow muffler... if it starts to pull off to the side straight away and then gets stuck then its probably straight through (Offset Inlet/Centre Outlet requires the pipe to be on an angle therefore broom stick wont go straight in)

I upgraded my TJ Sports standard system to a the redback catback.... dont bother if you ask me.. sounds a bit better but performance wise its a waste.. didnt make one bit of difference over the 1/4... if you just want sound, cut off your rear and spend the money on an awesome rear muffler ... i fitted only a magnaflow rear to my ralliart and it sounds tonnes better than the full redback system did on the sports.. mind you the magnaflow rear was over $300

I'm looking at replacing my rear muffler with a sports muffler, so they arn't straight through? But how is there such a large gain in kW over the exec muffler?

Because apparently the triflow muffler is the bottleneck in the exhaust system; it's extremely restrictive, so replacing the muffler with a free flowing design instantly improves the flow of the system. It's not really making you more kW's, it's just freeing up the ponies you've already got available.

because the exec muffler is a piece of junk....... the triflow still flows very well apparently... well like i said above i didnt see any improvment going from the triflow to a straight through on my TJ Sports...

anyway, ive heard stories about the Sports/VRX being more than just a muffler change over the exec...... ie ecu tweaks..... dunno what to believe really

Because apparently the triflow muffler is the bottleneck in the exhaust system; it's extremely restrictive.

say what? the triflow as fitted to my TJ Sports by Mitsu was fine... i think your reffering to the muffler fitted to the exec etc

2 pipes.. standard exec rear muffler

If you dont know what your extractors (headers) look like. How can you make the assumption that there the standard Mitsu ones?


well i cant really.. i will have a closer look.. i was told when i bought it, it had extractors on it.. so we'll see tomorrow when i have a look.. ill post pics when i can..

well the exec doesnt have a triflow muffler so what are you talking about :nuts: :nuts: :nuts: :nuts:

The stock exhaust (cat back) for 3rd gens (3.5L) is quite good for a standard exhaust system. The standard exhaust piping measures 58mm (2.3") at its smallest diameter on a bend, and 60mm (2.4") along its straight sections. The muffler is a quiet, yet very restrictive tri-flow design.

The stock exhaust (cat back) for 2nd gens (3.0L) is 49mm (2") at the smallest diameter on a bend and 53mm (2") along its straight sections.

The stock exhaust (cat back) for 2nd gens (2.4L) is 50mm (2").

Mufflers
The first port of call for a 3rd generation magna owner is to replace the restrictive tri-flow muffler with a straight through design. This will provide gains of approximately 8kW at the fly wheel.

Lukey/Walker design and manufacture the 3rd gen exhaust systems. The Lukey LR2779 is equivalent to the VRX straight through muffler, and is a direct replacement for the standard muffler.

...I'm pretty sure the Exec came with the triflow. Not that I've stuck a broom handle in mine to find out though. Anyhow, the point is, whatever it is, it's freakin restrictive. Get rid of it.

no it doesnt.. but yes the exec muffler is very restrictive..

Umm...just a point i think i should make guys...is that if a car is quiet...that does not nessisary mean that it flows bad...

I don't have a 3rd gen myself, mine is a TP EFI manual lol, but I do know a couple of people with 3rd gens, one has a TF the other a TH. They both have changed their exhausts and are not entirely happy with the results.

I decided to look for a exhaust that based around performance and practicality rather than one thats built to make a very nice sound. I came across vortex exhausts and since they're Australian :D and supposedly based around a new principle of how they work, I thought I'd give them a go. The website is http://www.vortexexhausts.com.au/

It supposedly works on the principle of creating a vacuum rather than backpressure. It also supposedly works much better than a straight through design through the creation of the vacuum.

On the front page the one I have is on the left of the picture. There are other websites that describe this muffler but I can't remember what they are! lol. That website is pretty simple. Anyway I looked around and managed to get it off Ebay, so from buying it off Ebay to sending it in to get it welded on it cost me only $110.

This exhaust sounds really good, but the thing I was most impressed with it is the feel of more power (it was noticeable, I don't know whether its pschological or not) and the car has been using less fuel since I have had it fitted. Since I now drive it harder I'm quite impressed! I can't give you a solid figure till I do some long highway driving, which won't be for a couple of months!

The exhaust is supposedly classified as a fuel saving muffler, although when they tested it on Today Tonight there wasn't much change. I think it had to do with the vehicle they put it on, the way it was driven, and a whole lot of other factors. Anyway I'm impressed with it, I think I couldn't have chosen a better muffler.

that does look interesting.

ok boys cheerz,

this thread got a little hijacked in the middle there, all i wanted to know was.....
is there any significant reason i should dump my standard sports system for a redback cat back system...?

thats all i wanted to know..
