exhaust question

[yota_head]

you will lose low end and maybe gain top end.

your engine needs a little bit of backpressure for scavenging purposes.

Indeed. From what I have come up with on the N/A's ,a 2 1/2" exhaust is the most you want. Or some have said ,if you know someone with a turbo upgrading ,get that off them and swap it on. I don't imagine your cleaned out cat would have a negative effect with the other elements in place. Unless you took off the resonator and have a more free flowing muffler on there.
