Twisted Steel Headers

The performance short-tube headers are constructed of 1-5/8” 16 gauge mandrel-bent tubing for strength and durability. A 4-to-1 formed collector is used on the header to decrease turbulence and increase exhaust velocity for maximum performance. This massive torque monster y-pipe utilizes high-flow 49 State Legal catalytic convertors which keep the system a true bolt-on package free of check engine lights.
