Which Cat?

[mr.paower]

ok I have a b16a3 swap in my eg and using gsr headers which cat will mate to my cat back...gsr or civic cat

depends which side you want to fit, the header side or pipe side. lol. In other words, you might have to weld a fit plate. I'm not sure if they just happen to be the same

ok wut I meant to say was which cat should I use without having to take my ride to the muffler shop to extend/cut piping...cause I think they have the same flanges just different lengths...

Let me no one knows huh...well then for those of u who swaped b series engine in eg civic which cat did u guys use integra or civic????

i swapped a B16A2 into my eg and the stock header that came with the engine bolted directly up to my stock cat.
i had it that way for about 1-2 weeks, it was working fine until I swapped to a CTR header and CTR cat, that didn't fit to my piping correctly so I had to take it to a muffler shop to get it extended.
