exhaust and headers advice
Im gonna end up putting borla back on my car I want to go with the Atak and xpipe down the line I want to add headers but borla recommended I wait for the zl1 exhaust with 3 inch and NPP when it comes out next 2 months. Does it make that much difference vs the 2.75 diameter ATAK with NPP? I want to be able to quiet down the headers , down the line I want to do CAM tune and CAI but want to make sure I choose the right exhaust with it... opinions?
