3 inch cat help...

[nissan_s13]

WELL, to start off.. I'm feeling like S**T now because I just bought me a 3inch cat for a completely STOCK kae . I'd like any feedback as to how much this will affect my cars performance. Dang, I've been looking on nico but that search button won't find the answer I'm looking for. "ANY" feedback will be fine, whether it be positive or negative, flame away if you have to.

Also, it would be very helpful if anyone could give advice to help with improving my cars performance since I have the 3inch now.

Thanks.

sell the 3" and buy one thats the right size. i belive stock entrance / exit opening sizes are either 2.25 or 2.50.

So from what you're saying, it won't even bolt up to the catalytic converter? Damn, that REALLY sux...

Another thing that I've been wondering is if I got me a High-flow cat, new header, and intake, will it help to equal out the 3inch catback?
