            Amazing sound

            Had these installed and the return is amazing. Really woke up my exhaust. You will need a tune for these or any other headers installed on an 18 or 19 gt.

            Just got these headers to go along with my corsa xtreme catback and i couldn't be happier, very intimidating, no check engine light and i can definitely feel the small hp gains. Thanks AM!
