I just had BBK headers and X pipe put on my car today. I bypassed the cats and had it go to stock exhaust.. The power is amazing, but not quite happy with the sound. I'm looking into ordering the Borla trouring catback exhaust for it. Will I need to tune my car again? I wasn't sure if i should take it back to the shop to have it professionally installed or if this is a job i could do alone without retuning. Please let me know your thoughts/opinions! Thank you!
