Stainless upgrade exhaust
Ford Powerstroke from 1999-2002
The 4” mandrel bent stainless exhaust is
designed as an upgrade to the cat back exhaust system. This ATS upgrade system
lets one run a three-stage computer module or the Torque Pro 2000 L.P.G. assist
system in conjunction with a computer module. This system comes complete with
hardware, clamps and hangers to hook up to the ATS cat back exhaust system.
