decided to go with 2.25 ITR exhaust system w/ bottle necks removed for quietness. but not sure which cat (for longevity)..
all this will be in the car by spring. all tips/recommendations are welcome...looking to hit 13s.thanks all...PAYCE~!

 

everything looks pretty good. I'd spring for a full 2.5 exhaust and a 2.5 highflow cat (or test pipe, obd1 after all ) to go with that header. There's no point in messing with the stock itr exhaust when you can buy an aftermarket stainless system for around 400.00. Good luck, get the machine work, ect done right and you'll be fine

 

thanks, but im deciding to go with a 2.25 just to keep it quiet and stock sounding....unless they make quiet 2.5 exhausts which i doubt..

 

apexi world sport is quiet and I think it's real close to 2.5. It looks stock, but with some bling! I don't know why you want to build a motor with stageII cams,ect and put a stock exhaust on, but to each is own I guess. I've heard the WS is very quiet, of course the mugen twin-loop is supposively quiet also, however not on your wallet

 

yea, i know, i runnin all this high comp **** and im forcing it out of a 2.25 hopefully i can do it...im gonna push to see if it'll work out alright, if not, then i guess i will have to change it...but hopefully for something real quiet...maybe the Rsr Exmag....
