what do yall think about this???

a three inch full exhaust, performance cat, performance muffler, deleted resonators, and custom header?
would this be letting out to much? right now i have a intake with throttle body spacer and i feel like im letting the engine get too much air in but not enough out. give me some input please...

 

three inch is not needed. Doug Thorley headers, magnaflow muffler for performance flowmaster for sound, new y pipe if you want but it wont do to much.

 

Yeah, I agree three inch would be pushing it a little. I went with 2 1/2. But I'm not saying YOU have to.

 

so how much horse power gain would all that do??? i have a borla cat back right now. would cutting off the resonators do about the same thing?

 

No it would probly just make it louder. The headers will do the most out of anything.
