custom exhaust

[gohan69]

looking to do a custom exhaust to get more power and mpg just wondering what size pipe i should go and what kind of muffler would be good i dont want a crazy loud sound just performance Also I have the 2.2 2bl



Thanks

hmm... a cheap way to go is to take off the resonator, that way it is stright from the cat to the muffler, my reliant had a new exaust system and they didnt put the resonator back on, it sounds awsome. plus it prolly helps with performance

Well i saw a youtube video where a guy puts on a cherrybomb glasspack and it sounded awsome. just a thought.

On my 2.2 turbo I put a high flow cat and a high flow muffler and a 2.5" exhaust pipe. It's a little louder than it was before.

if you have a naturally apsirate 2.2 or 2.5 - don't go over 2" diameter pipe - you will sacrifice low end response and torque for the sake of high end breathing. better idea is to replace the stock catalytic converter with a high flow unit and get a low restriction muffler. these engines like efficiency of flow over volume of flow - you want to keep exhaust gas velocity high.

on a mitsu turbo equipped car - 2.5" exhaust all the way. the downpipe is 2.5" as of 1989 but the rest of the exhaust is smaller and restrictive. go to fwdperformance.com and get a 2.5 inch mandrel bent system (available in stainless steel too). the kit for a spirit is correct for atleast a 4 door/wagon k car. consult them for other applications

if you have garret turbo (especially intercooled applications) the ultimate setup is a 3" fwdperformance.com system with a 3 inch swingvalve from turbosunleashed.com. the bigger swingvalve will give you 5 more hp and 30 more ft-lbs of torque over a factory 2.5" swing valve. its pricy at $250 but worth the added power with no compromises relief it brings!

the reason you don't want a 3" exhaust on a mitsu turbo car is because it will easily overboost. you just want to clean up the airflow and uncork the restriction.
