We hate to be the ones to tell you the bad news, but stock Scion exhaust headers just aren't optimized for maximum horsepower and torque. The good news is that AutoAnything buyers have our shelves teeming with great performance Scion exhaust headers. These headers are carefully crafted from mandrel-bent tubing so you get the most efficient and least restrictive path for your engine's exhaust gases. Our Scion exhaust headers also increase engine scavenging which siphons exhaust away from your engine. Finally, with our 1-year lower price guarantee, it only makes sense to get all your parts and accessories at AutoAnything.
