AE101 Exhaust

[GTCRSHR]

ok well i tried searching ... but not much luck ...

so what im after is a bit of information on exhausts ...

i have a 1994 ae101 fxgt eith superstrut ...

the standard Twin exhausts ....

so what im after is my 1st mod to the engine/performance side of things is the exhaust ...

so heres what i wanna know .. i see quiet a few levins driving round with modded exhausts but with just the one

why is that ? what bennefits are there between the one and 2 ? should i stick with two ? or just go to one

also what exhaust should i be looking for size wise ...

oh i will be getting it straight from the cat? new piping everything not just the muffler ....

so what should i look out 4 ? any good brands?

i dont want it too loud just a nicer sound would be good ...

i will go in and see a exhaust place when im ready i just wanted a bit of info 2 go in there with

cheers guys ....

talk to actionDan, but if you get him to do work on your car make sure he uses smaller piping than 2.5" unless you are going turbo.
he does very good work, but 2.5" on an n/a 1.6l car is over kill and noisy

[GTCRSHR]

well yeah i forgot to mention something ...

i will in the future be wanteing to go turbo ... but thats not for a while yet ... what would the differences to the piping make on the turbo ?

whats the standard size piping on the fxgt's ?

so 2 1/4 ??? piping and what about muffler etc...

[RAZA]

go single - saves weight and expense and theres no reason why you cant get the same amount of air out of a good single setup as a twin.

seems like a good setup these days with all the trouble with wofs and cops is 2 1/4 inch pipe , two straight through resonators and a straight through muffler on the end of it all.
can be a bit hard finding space for the resonators though.

Probably the best way is to have a chat with your local exhaust shop and get their advice. most of them will be happy to give you some advice without forcing you to commit to having them do the work.

as far as turboing goes, you'll probably want bigger pipe and less restrictive mufflers if you turbo as back pressure from the exhaust makes your turbo less efficient.

down pipe on FXGT from extractors to cat is 2.5"

[Loudtoy]

U'm my pick would be 2 1/2 inch! Makes a far nicer sound than the normal strangled tinny sound 2 1/4 will tend to give your car! Buat apart from that go single with the least amount of bends possible with two resonators, preferably louvered, and one decent straight through mufler! Make sure you get a decent branded one as the cheap ones crap out even faster than usual on 20 valves for some reason!
Remember these motors love to breath so it may even be better to do your intake first or even at the same time as your exhaust as they pretty much go hand in hand on these motors

[GTCRSHR]

so the factory intake isnt good enough LOL!!!! so there inhole is a nother thing to do any body have any suggestions?

maybe ill just go in a nd ask the specialists then ? its a toss up between 2 1/4 and 2 1/2 now ...and 2 resonators (is that to quiet it down) so what about mufflers good brands? whats a nice sounding one if they do make such a difference

[deaf_rattle]

my mate got an action dan exhaust, and it sounded like crap to start with (due to piping size i believe) but once he had an extra resonator in there. (total of 2 resonators and one action dan muffler) it sounded really nice for a 20v.

[Distrb]

brands dont mean a heck of alot.... as long as its constructed properly, then it will do the business....

make sure when you get it fitted, that it hangs as close to the undertray as possible.... you dont really want it dragging along the road.... what with all that weight you're going to put in your boot, the back end is gonna sag until you get some decent suspension

i'd agree with loudtoy on the size piping...... otherwise you get it sounding like a damned hornet nest.....

[Lanius]

If you're *definitely* going turbo later on, then just get 2.5" pipe with a couple of good resonators ... save yourself having to get a whole new exhaust later on when you fit the turbo.

Single pipe usually means easier air flow as there are less blockages / bends in the pipes. The stock Levin and Trueno exhaust on GTZ's (not sure about GT-Apex's and FX-GT's) is 2.25" back to where the pipe splits into two, then they're 2" back to the mufflers. You'll find that one of the mufflers is bigger than the other as well. Single muffler = lighter, less bends etc.

RPS mufflers are good, sound decent. Deaf_rattle is right about the noise though, so make sure you get enough resonators if you go 2.5". They will help the exhaust sound deep and throaty, rather than raspy and tinny

Get your cat gutted or removed as well.

cheers 4 that so 2 1/2 inch it is ...

so is there anything else to look out 4 or that i should upgrade while im at it ???

what about the size of the muffler and the pipe coming out the muffler (must have a name )

cheers guys

[GTCRSHR]

Get your cat gutted or removed as well.

whats gonna happen when the law changes?

[deaf_rattle]

keep your cat, but not in the exhaust, get some flanges put on it so when the new law comes in you can bolt it in for wofs.
cats stop working properly over time anyway.

we got a new vehicle for work and one of the things you have to do is let it warm up without reving so you dont stuff up the cat.

you may find your cat isnt working properly anyway, but keep it just incase.

[GTCRSHR]

so having it gutted would do the trick ???? that would mean its still inthere but not hing inside correct?

is thre a problem doing that ?

[Distrb]

my advice to you is to get your new exhaust made to fit to the downpipe flange, rather than the end of the cat..... that way you dont have to mod anything, and you dont have to worry about doing something about your cat converter

and keep your old exhaust and the cat converter (whole, not gutted) somewhere safe, just in case you ever have any problems or there are any new laws made etc, then you can just bolt the factory gears back up and you're all legit again.

this is what ive done with mine, and it works perfectly

i have 2.5inch, hand made mandrel bent, 2 louvered resonators, and a stainless muffler (2.5" inlet and 4" tip) i have suspicions the muffler is actiondan crafted but not too sure bout that....

Extractors / flange? Intake? (Cold air, induction pipe, port and polish if you've got the cash to spend, cams, pod filter ... the list goes on).

[neo]

my cheap alternative = take out the cat (replaced with perferated coby)..
and the rest factory...
its all good till the rear mufflers, but then again apart from the massive bend before each, they are free'flowing... its just that they are so darn big that they are quiet =)

... but its a whole different ball game for the turbo setup...

i ment while the exhaust is being done ...

so either cold air box or pod filter and the exhaust at the same time ...

again the turbo is a MAYBE at this stage of the game ... so i can just get this done now ... and if i go ahead with it later can maybe sell it off or what ever

i have 2.5" twin exhaust on my GTZ, had 2 resonators in originally, with 2 rps oval mufflers and it was f*cking load!! Got another resonator put in, and was still a bit load but way better!!

The oval RPS mufflers seem to stuff up on gtz's tho, i went through about 3 or 4 mufflers. Then got some mufflers from magoo in chch, its almost as quite as it was without exhausts done! I am tempted to take out the 3rd resonator now.

But make sure you get plenty of resonators in there if you dont want to have your stereo turned up to full volume the whole time!

[GTCRSHR]

hey thanks 4 that man ...

a lil hint about that having 2 turn ure stereo up ...

if u use some bostek tiles on the floor of ure car (sound deadanning) it will make it 10 times better...

it takes a bit of time ... as u have 2 rip the seats and carpet out ... but it worth it
