I am Getting the stage 3 intake manifold and to gain full power I need to remove all air restrictions. Right now I have a injen shortram with muffler delete straight pipes. Should I remove the resonator? If yes with what?

do it im running catless down pipes and a catback straight pipe to magnaflow muffles with no resonators, go for it, lot more power

^ Also has a 335 where catless downpipes produce huge power. On a 328 you wont tell a thing.

I did the 3-stage with res delete, and secondary cat delete and it came out nice. If your going to remove the res. just remove the secondary cats also. It's worth it.
