Finally getting my ZR-1 back from Corey's!!!

Yeah, I was already thinking of replacing the Borla resonator with an x-pipe. I've been under it and looked at the inlets, and they are really restrictive. Once I get the new injectors back and finish up some exhaust work, I'll re-dyno. May even have Corey retune after that.

I just removed my Borla resonator and replaced it with an x pipe. The car has less resonance inside than it did with the resonator in place. I was very surprised! Im glad the resonance is gone, but I wish it made a bit more noise. My Bro was following in his vette and he said it still sounded pretty mean from behind though.
