This system is recommended as the minimum exhaust modification to run either a single stage computer module or the Torque Pro 2000 LPG Assist, individually, but not both at the same time. When using the single or three-stage computer module in conjunction with propane, the 4” stainless exhaust is recommended.

This ATS cat back exhaust is manufactured out of aluminized steel tubing with an aluminized steel muffler. It comes with all brackets, clamps and hangers. With the ATS cat back exhaust installed, one can see as high as a 200 F drop in exhaust gas temperatures with as high as a 15 H.P. gain in power.
