Re: ? bout my 92 lude si

you mean with the header and nothing else or not even a header? i started mine without nothing and its sounded like a real ****ty supercharged lawnmower. and when i revved it i thought i was gonna cry. it sounded like i unleashed a hideaous demon. i wouldn't recommend it. i wouldn't recommend either though cuz i would think there isn't enough backpressure

Re: ? bout my 92 lude si

get a header, straight pipe, and a hi flow cat, and put your stock muffler on. Sleeper that bittch. You dont get much but maybe .5 hp if that from a cat back exhaust.

Re: ? bout my 92 lude si

wouldn't the muffler hold back alot of its potential? like whats the point of doing header and high flow cat and stright pipe if there's a muffler holding all that air back still. i have ebay header, testpipe, catback, CAI and my h23 ran 15.414 with valve tap and all. exhaust does make a difference or people wouldn't bother with it

the muffler doesnt hold back THAT much air...plus there needs to be some back pressure or you will actually loose power. the cat is what holds back most of the air. i have a high flow cat, headers, the rest is stock, and i could feel a good increase in power.

Re: ? bout my 92 lude si

i was just sayin it could use the extra power, taking the muffler off and having the Greddy catback for example isn't gonna make it lose all backpressure. my setup like that seems to work perfect. i had jus the exhaust and when i put the header and testpipe it improved it so i don't think that would make it lose all backpressure

Re: ? bout my 92 lude si

Open Header = LOUD AS FUKC. I originally just had an AEM CAI on my car, then I added a Megan Racing Header, a test pipe, and a Tanabe Medallion exhaust, and it's definitely a noticeable improvement. It's not gonna shave a second off your 1/4 mile times or anything, but it will help more and more with power mods you might add down the road.

Re: ? bout my 92 lude si

You do lose horsepower if the flow is too much. Back pressure actually helps keep your hp. I watched a whole video explaining this. Its not the amount of air escaping, its the velocity of the air that escapes that helps create hp.

and stock muffler is perfectly fine. If you ever listen to those damn ricers a lot of times their exhausts make a popping sound from a backfire. Which is no good. You do want some back pressure.

If you do intake, header, and full exhaust with stock muffler you'll still notice a gain, and you'll save money in the end from all the tickets it'll save you

Re: ? bout my 92 lude si

ok nheres wat i'm saying. i started off with intake and exhaust right. so that has some backpressure, more than with header and test pipe. when i added the header and test pipe i still noticed gain, not loss. i don't have no backfiring problems or anything.

and as for shaving seconds off, i've read a stock h23 runs about 15.9 completely stock do doings those simple mods knocked a half a second off my time which isn't really bad at all

I agree.. you don't need a full aftermarket cat-back system when custom can be such a cheaper solution, mine looks basically like an n1 system, but I have cutom 2.5" with header and high-flow cat to a Nopi titanium muffler... to me the cat-backs are too high to bother. It you want to keep the stock look, check out a magnaflow or something cheap... but I would loose the stock muffler IF I did the header, cat, and pipes..

"popping sound from a backfire. Which is no good."

Dang...I never knew that. Do you mean the constant raspy noise or an actual backfire (air & fuel ratio)? My car backfires like crazy from 1st to 2nd gear and 2nd to 3rd gear (one loud pop, sometimes with a visible explosion), but I didn't lose any performance. It backfires every now and then when I downshift and coast. But is this really not good? And my exhaust is not raspy...it's more deep.

Re: ? bout my 92 lude si

When I downshift to 2nd to engine brake, I get the occasional pop, no visible combustion or anything though lol. Are you 100% sure that this is bad? I've seen some bad built imports around here that were built by experts and do the same thing.

if it does all the time I would guess it needs a tune up or tune... someone above mentioned too much fuel...

mine was dyno-tuned by the pros that did my swap, suspension, etc... all since march, and from the time I got it, it will pop on occassion (mine likes to do it a little if I let the revs fall pretty low, or on a downshift as you said...). I think it has to do with the exhaust flowing so effiently, not an issue if it occassional.

Yeah, I didnt think it was that bad either...the backfire only happens if you run through the gears hard.

Re: ? bout my 92 lude si

I drove my car 13 miles, open header to get my exhaust put on (4th gen) and I had a massive headache by the end of it, thanks in large part to the fumes, but also the annoying sound.
