I have the MBRP race catback exhaust, and was wondering if I straight piped these 2 mufflers would that affect emissions/require a tune and pass inspection? Love the rumbly sound as is but seeing if I could wake it up even more since I'm not going with a downpipe for now. Also would it trigger a CEL since I read the backpressure changes could?
