some help with exhaust

[Crunkrich]

jus a few quick questions... i have an NA ka24de all stock right now except I ran the intake down into the fender under the battery instead of across the radiator. I have 2.5" exhaust tubing, a magnaflow muffler, and maybe a resonator.

questions: should I replace the cat with the resonator, or leave the cat on and put the resonator on also after it? will I be losing too much backpressure by being NA running 2.5"?

I was thinking that with the real short tubing cold air intake and the resonator w/ cat I would be ok, do you think that sounds about right? thanks!

seeings how ur in cinci i hear they did away with echeck i would remove the cat alltogether it will breathe better without it. just put a resonator where the cat is.
