If you install HFC’s I would install the AAM Competition HFC’s since they lasted the longest in my experience. Definitely try to find some other people with Z’s and hear their exhaust in person or check out YouTube and hear some sound clips it should help you find the exhaust you like. Look at different brand catback exhausts.
