The factory Scion tC headers leave room for improvement and a lot of it can be gained by lengthening the runners and easing the exhaust into a single pipe that is why we offer great aftermarket headers with nothing but performance in mind. Our high quality Scion tC headers are very high quality and lengthen the runners to improve the power band and smooth it out. All of our Scion tC performance headers are very strong and more than capable of handling the extreme heat generated from high RPM exhaust flow.
