hey. i have gthaus catback with test pipes which means my exhaust sound is HNGGGG
my question is for those who installed a CAI in addition to their gthaus exhaust.. are you able to hear a noticeable difference? are you able to notice any difference? my friend (in another city) has the stillen gen3 CAI and the gthaus exhaust but says that he cant even hear a difference from his CAI because of his exhaust.
let me know your opinions? thank you in advance!!
