I have a dual exhaust setup for my 99 2.4, i had an exhaust shop do it, its 2.5" from cat back, the cat is stock, and i am planning onreplacing it, and my qustion is should i get a resonator or the high flow cat?
I would def. get a high flow cat, as far as the resonator goes if you happy with the sound then no you don't need to, personally I would get a magnoflow resonator just for a better quality of sound
Do u get both high flow cat and resonator or one or the other?
i have both the high flow cat and resonator.

Im a Xbox 360 fanboy...and damn proud of it!!
How does it sound, and how far is your resonator from ur high flow cat?
