Fast Intentions cat back exhaust and resonated test pipes
Hello. Im pretty sure this question has been asked and you guys seen this multiple times. Right now I just have 12" resonated cat back and looking into buying the resonated test pupes from fast intentions as well. Is there any videos around with that set up and if anyone has the set up how much louder does it get, if its significant or just a little bit. Any issues with the check engine light? I have a 13" g37x sedan.
