I was thinking about getting a new exhaust put on the CRX, but I am not sure if I want go to with the 2 1/4 in (On there now, but rusting and shi*tty sounding) or go with the 2 1/2 in. I am running a N/A B16a CRX w/N2o. Would 2 1/2 be too big, or would it sound good and help performance?

I'd just go with 2.25 inch from the cat back...just make sure it's stainless...even with NOX, you are'nt gonna have that much back pressure...hope that helps.

 

I got 2.5 on mine and it is still loud but not ricey sounding. bot a cheap arospeed muffler and a nice tip. got a dc sports 4-2-1 header and a high flow cat with 2.5 all the way.

 

what high flow cat meats up with the exhaust manifold. are there any with flanges that meet up or will the flanges have to be welded...

 

2.25 should be good.unless some one that has had both really knows.have you ran since the n20?ill be there wed you?

 

hm, i have stock header, 2 in piping to muffler, no cat, no res

i want to go 4-2-1 , 2.25 than muffler

will that be good enough? for back pressure, etc?

 

Yeah, I've run it with the N2o, but I'm wasting my time as long as I am trying to do it on these stock Micheshitties. I went from doing a 15.1 @ 2.3 60' to a 14.8 @ 3.0 60'. I need to get a hold of some slicks or drag radials, then I'll try again...
