I am sick of the standard exhaust on my 98 Magna. WHat do all you guys recommend. I think I will only go cat back for now. what size pipe and all that. I want to try to get more power outta it and also a lil noise not too much but just something cos the standard one is really crap.
Thanx in advance.

This has been done again and again and the best thing to do when it comes to magna exhuasts is just swap the rear muffler with something better flowing.

The stock magna exhaust isn't a bad pieve of hardware really being 2.5" mandrel bent system although the rear muffler is a little restrictive.

Or you could do what im doing and do a twin system from the cat back.

PEOPLE PEOPLE PEOPLE , you cant really upgrade a magna's exhaust , all you can do to get power is replace the muffler and extractors replacing the any other parts will loose you power.

You can tell widow has learn his lesson.

When you getting it fixed mate?

Sure you can upgrade your exhaust, if you want you can upgrade any exhaust depending upon your needs. If your car is otherwise stock or close to it, go for a muffler only, lukey have a good selection and most reputable fitters should be able to help you, talk to a few shops before settling on anything.

Sure you can "Upgrade" Anything but to upgrade the magna's exhaust is gonna cost an awful lot of money and for the money you dont get any good gains hence its not worth it.


You think im just saying this to stop you guys gettings exhausts ? no im trying to help you wasting money like i did. you do whatever you want.


hmmm blake , i dun know probably not for a while

Unfortunately Widow, I think you got touched by your selected exhaust supplier. Gains are gains, if the next thing after the exhaust is inlet changes, camshaft, fuel supply or even a new engine then all of a sudden the exhaust upgrade is needed and justified.

As you dont seem to understand "Hard-Head" let me simply explain it to you in a few words. The stock magna exhaust is 2 1/4inch Mandrel bent all the way through , so it is well suited to that engine so much so that to go anybigger will not really gain you anything and will cost allot of money. let do a little math , lets say you wish to replace your exhaust with one better then the stock one you would have to spend over $1500 to get a BETTER designed and built one then the stock one. that is not inlcuding a pair of headers , now with this new $1500 exhaust you will gain perhaps 5kw's at the wheels. now lets say i have a lancer GSR i take that $1500 buy a second hand turbo and intercooler and suddenly i have gained well over 20kw at the wheels. do you see where im going with this ? if you want to really make your car fast then stay clear of anything mitsubishi ( not including lancer gsr or rs model's ) because to make one quick you will have to have thousands of dollars when you could of just bought an imported Nissan Gtr pulsar.

Yes ofcourse you can upgrade anything , if i had my car setup to run 3 second 1/4 miles you would say you couldnt upgrade it , but in return i would say yes i could but you would need to give me $800,000 in order to do so.

If you want to waste money to get a new exhaust i have no business in telling you what to do , your wasting your money not mine. Some people think just because they have a fully sick exhaust that is so loud it annoy's everyone that there car is more powerful and faster just because its louder. Do what ever the hell you want. And STOP beleiving everyone not everyone speaks the truth infact most people talk BULLSHIT all the time! oh and buy the way where i got my exhaust wasnt a back yard job they are one of the best exhaust makers in australia , so even they bullshitted me and how do you think i feel ?

Unfortunately Widow, I think you got touched by your selected exhaust supplier. Gains are gains, if the next thing after the exhaust is inlet changes, camshaft, fuel supply or even a new engine then all of a sudden the exhaust upgrade is needed and justified.

Yes gains are gains but where do you pull the line , if i said i could make you rich and be the king of the world but i had to kill your parents would you agree ? of course not. on the same token 5kw isnt worth thousands of dollars.

If you want to get a new exhaust , headers , cam shafts, cam springs, fuel supply you talking over $5000 and when you could of just gotten a quicker car in the first place what the **** is the point ?

and getting a new engine is stupid for the same reason. THIS is why i bought a hachiroku because for under $10,000 i can make it quicker then a WRX or any magna in australia, perhaps your better off with another car hardhead , because you dont seem to understand basic concepts.

The biggest problem I can see with people specifying their own exhaust mods is just that, telling not listening, I say talk to a few different shops and go with what makes common sense. People go on and on about mandrel bends, whilst mandrel bends are the premium way to do the job it's not mandatory, if you go up a size or two you can do without the mandrel bends and go for press bends. Mandrel bends are where the money comes in, most shops say if that's what you want then you can pay for it, not all though.

I've compared two and a half inch mandrel bent pipe to two and three quarter inch press bend pipe on the flow bench and for absolute flow capabilty there's nothing in it.

Also stainless steel, it's not needed, most decent suppliers are using 16 gauge steel which is going to take a very long time to wear or rust out, why spend the money on stainless.

Now I realise a few of you think I'm full of shit, well that's okay too. I'm the first one to admit with gearboxes and diffs I don't know a hell of a lot [and happy without knowing it], but engines and getting power out of them, is a subject I can hold my own with. I've said it before and I'll say it again, I'm 37 years old, I 've been there and done that and still doing it, I've seen most of the mistakes and I'll help any of you if I can with advice. I've had one email suggesting I'm on a commission with RPW, well that's bullshit, if I think someone has a good product I'll let you know about it.

That's a classic, you lecture on spending money, but you're the one wasting money on pricy exhaust systems, what else you got done to the car...?

Doesn't matter what car you buy, sooner or later you're going to want to go faster if you are competitively minded, seriously, $5,000.00 isn't a huge cost. Any idea's on what the real quick guy's spend on engines...? Didn't think so.

the thing i DONT understand is if you have a good thing such as a well made mandrel bent exhaust is why the hell do you want to change it ? you said YOURSELF that they are a premium and that's why the stock exhaust is good. And i can tell you i have spoken to many people and exhaust shops and everyone has there own little opinion and no one actually knows the right answer, most places are full of shit and just want to treat you like shit do a shit job and charge a high fee.

I never said anything about using stainless steel as that is a waste , i mean in 8 years where can you see your car ?

And as i have said so many times it doesnt matter if you 2 years old or 82 . i dont have to finish that sentance, If you are of such age and so wise i would have though you intelligent enough to know that wasting such an amount of money for such little gain was pointless.

What has this got to do with RPW ? im sure David doesnt really want his business brought up in such a conversasion, even though with Rpw's reputation it doesnt mean that everything on there page is correct ? i mean you can gain 8hp at the wheels from a pod filter. yes i beleive anyting, come on people start thinking for yourselfs and dont listen to everyone , anyone get register a webpage and start putting false information onit.

well it has got to the point where i cannot help anyone in this thread because you wont listen not only to point but to common sense and logic.

last time i checked a magna was a "real quick car" i know people that have cars that run quick quater mile times , and just because there car's are worth over $100,000 doesnt mean i dont know anything about car.

And as a classic case of just midless typing but not auctually reading anything , you will note that i said on real performance cars it is cheaper to make them go faster then family saloons.

I didn't say you said anything about stainless steel, it was generalisation.

I didn't say you said anything about stainless steel, it was generalisation.

Just like everything else you have "Generalised" about me.

hard head i think we should agree to disagree and leave it at that we are 2 different types of people. i like saving money and you like wasting it simple as that.

What kind of money should one expect to pay for a set of extractors on a 3.5?

What kind of money should one expect to pay for a set of extractors on a 3.5?

Come on fella's take it easy, lets not turn this into a fastmagna thread where everyone sinpes at eachother. :mrgreen:

I learn about exhausts :D I also couldn't justify getting a stainless steel exhaust.

Oh well... Juct my two ceonts

Hey all,

just a quick one here - you are all saying the magnas come with a 2 and a quarter exhaust - i have a TH with a 3.5 and was told it came with a 2.5 stock - so i just changed the rear muffler to a lukey and added a small - single chrome tip - tone is nicer but it isnt loud and i honestly couldn't tell the difference in power as i had only had the car 2 days and went from a 1.3L carby corolla to a 3.5L MPI magna - to me the power was huge before the muffler change - but i wanted the tone to match - witch is why i got the muffler changed - i went to RPW and they put me onto one of their subbies - who was busy - who in turn put me onto on of their subbies who did my car the following day - some guy in north bridge - small shop out the back - but he did well!!

and when he first started it up i couldn't believe it sounded so nice!!

however!!! i am sick of the bulldhit thrown in between widow and hard-head - (aka in the know - shoulda stuck with the tag - at least we recognised it) most cars will benefit from some change in the exhaust - for the magna it is the extractors and muffler - some other cars need a larger system - liek the nissans that come out turbo with a 2" zorst - to run nice boost they need to instantly jump to a three inch - why cant we just leave it at saying - yeah wodow got ripped and for anybody thinking about and exhaust change - just try the rear muffler and a set of extractors - the only reason to go a full new exhaust would be to have a a twin system setup - but isnt really necessary for power!!

this was a nice quite forum - oh well :roll:

People understand that it's going to COST money to upgrade these cars. So when you say you don't want to waste your money for only a couple HP, you will find that most people on here will spend that money coz they're keen on getting every little gain out of it. If your exhaust is already 2 1/4 to 2 1/2 there's probably no point upgrading purely coz you're just buying the exact same pipe again. Just buy a hi-flow muffler and extractors and you'll get the performance you want. For the enthusiasts out there, getting a well tuned exhaust can make improvements, but the dollar to power increase, the gap becomes bigger, ie, $1000 for 1-3kw.

thanx for the tips. i am goin for a new hi-flow straight thru muffler.
thanx again

Where does this $1000 mark come from?

I'm only spending 490 on my exhaust...I dont see why people are spending so much...Fair enough I'm not getting stainless....Reason being is that I can't justify the cost. If you're talkin stainless then I understand...but if not..I think you need to find another exhaust place.

I got a cheaP! sport exaust From mitsubichi
for the 3.5 and welded it on to my 2.4 4 cilnder altera :D
lol,
Impruvment was verry small but noticeable!
bit more hp....
:D
the flange was bigger so i cut it off and welded the one from the old exause in that! and now My altera Sounds AwsoME!!! not to noisy at all... perfect tone :D

lol, im so cheap! what do u think about what i did? sound ok? Or not worth dowing??

hey if it helps do it, nothing wrong with being cheap... its called sensible.

$1000 was just an example, i only paid $150 for a 2 1/2" cat back, including resonator, $270 for the magnaflow all fitted so i'm into getting anything as cheap as possible.

mate
i went against what every1 said about just getting amuffler
i got a 2 1/2 cat back system.
the stock system is 2 1/4.

Its a redback straight through exhaust with hiflow muffler, its made to fit the magna and takes the shop u go to about 15 minutes to put on.
cost about $400 depends where u go.

when i got mine, i liked the sound, not terribly loud, but has a nice rumble at low revs, but when u put the foot down the sound increases alot.
apon testing the car out just after i got the exhaust put on, i could not believe the power increase, was quite unbelievable....

just my opinion, maybe it will help u, maybe not..

cheers and good luck

Ice_Magik

WTF!!!

YOu paid 400 for your redback system~!

dude my muffler only set me back 250!

or did i miss something else.. errr..

Yeah I also run the redback system... mild steel... 2.5" cat back exhast system (mandrel bent) the system cost me 360 + 50 for a chrome tip :p

Have been running it for over 12 months now without any problems... sounds mean especially when you get it hot. But when it comes time to back off and do some sedate city driving... I barely realise it is there.

I would recomend it to anyone!

to get an idea of what the readback system sounds like when hot and giving it a 'mild' foot on the floor.. download my corner video where i accelerate mildly outta corner... sounds beasty!

take care

"BOOYA"

what ? where can i buy this redback mandrel bent system for 360 ? i want it now now now now !

you should be able to get a redback system for under $600 easy from anywhere

i got a dual 2.5" cat back with two redback mufflers for $570 with two 5" tips

the muffler on the left dont fit as esay as the right one

and they dont sound like a misquito on steroids like most other single mufflers do on a magna

as for perfor. i didn't notice much, but at high revs it was little smoother

as for time 1/4 best time of 15.07sec

after the exhaust my top speed increase down the 1/4 mile from 163kph to 167kph

that's about it thanks

I just got mine through a local midas store. They ordered it in and bolted it on in under half an hour. Have looked under the car and they are deffinently mandrel bends.

sorry the speeds are wrong

143 to 147

hey megatron - you got pictures of your exhaust - i wanna check it out

u saying u have 2 x 2.5" exhaust cat back with 5" tips for less then $600??

damn - thats what i want - but not 5" tips - that is 2 rice for me - but dual 2.5" tips would be sick!! i want i want!!

Manual

Manual

my mistake

dual from rear axle back, the rear axle onwards (originial exhuast) was crap it when from 2.5" to 2" resistor then to the muffler. why would they do that??

so i got the a Y put in and 2.5" dual from there to 2 redback mufflers

i'll try and get some pics on the weekend for you

Hey Manual,

You say you got a lukey muffler and that was it...Im just wondering how much they cost. YOu see ive read what you all have to say here. My opinion is that im not after the power. Im happy with the power the 3.5 produces. All I want is a deep rumble at idle and a mildly loud roar when its pushed. Im not after more power and shit like that...

Can anyoine help me or understand what im saying?>>>

Thanks

Chris

Am i right saying this...

My TF 3.0 have 2.25in standard exhaust piping. To my knowledge 2.5in standard exhaust piping applies in 3.5 Magna...this is right...right?

Cheers guys.

hey LiquidHot, how much through midas? im thinkin of going through them, as they gave me a fairly decent quote.

Trav

i was under the understanding all the 3rd gen v6's have 2 1/2" exhaust systems, which the guy at the exhaust centre also said.

i was under the understanding all the 3rd gen v6's have 2 1/2" exhaust systems, which the guy at the exhaust centre also said.

No. My TF isn't 2.5'. Not when I did three spot checks and it's 2.1', 2.2' and 2.3'. I'd say it's only for 3.5's too. Wonder if the optional 3.0 in the TH range get's 2.5 instead, (actually, MMAL told me it's 60.5mm which is closer to 2.4' than 2.5').

Yeap,

Then its true that 3.0 engine have <2.5in piping, until 3.5 came out...:)

yeh mainly the TE/TF's have about 2 1/8 - 2 1/4 inch systems. the rest is 2 1/2.

Trav

P.S. Liquid hot, u out there man?

the dude at the exhaust shop told me chrome exhuast tips tend to change colour with age due to hot exhaust gases. what abt stainless steel? can someone do a pro and con thing for both materials?

To my knowledge,

Chrome or polished will get discoloured when excessive heat involves (ie. exhaust flames or when your car running to rich of fuel). Some my friends car tend to do that...its a normal thing...and a mild discolouration only at the tip of the exhaust...not a big problem.

My friends have a Ralliart Magna, even the exhaust tip of that Ralliart Magna went to rust already...so common sense...it shouldn't be a stainless steel. While i'm using Hitech exhaust since 1999 and it never went rust...so go for stainless steel (but then its up to you for chrome or polished finish)

Went a long at the same story...as well as Magna windscreen wiper arm...people will notice that the arm will start to get corrosion from rust.

These are generally problems in Magna quality use...not designed.

Hopefully my 2 cents worth in your mind... :idea:

3l and 3.5l are both 2.25in mandrel.
i believe 2nd gen are 2.1/8th

My 2 cents. I have the 4g63 motor. I wanted more power. Thinking exhaust was a good first step I went to the exhaust shot to dicuss.
I wanted a full 2.25 system with a set of extractors(pacemaker) and I supllied the hiflow cat.$800 later the first stage was done , catback and 2.25 sports muffler out the back.
Small improvement in sound and performance. 2 weeks later I went in for my pacemaker extractors and the new flex pipe.
WTF I lost power, a good 15 hp, the sound was quieter and take of was terible. Very unhappy. Turns out they never fitted the pacmaker as they don't make them for my motor(4g63) so I got something he called Hurricane ectractors.
Very dissapointed. To find out why this hapend is a long story, basicaly the factory headers are the best for any motor. Performance can only be found in a mufler or cat back with hyflow cat.
Just what I have since found out.

first post is a 3yo thread mine...umm congrats :rant:
