The ATS 4” mandrel bent Stainless Exhaust System for the 1999-2002 Ford Power Stroke diesel is a very impressive exhaust system. This exhaust system starts at the turbo discharge with 4” and ends with a 5” polished stainless tip that is slash cut on an angle. The slash cut end has a rolled edge so there are no sharp or unfinished edges and is 24” long. The muffler and polished tip are constructed of 304 stainless steel and the tubing is constructed of 409 stainless and mandrel bend.

This system lets ATS produce over 120 additional horsepower without exceeding stock exhaust temperatures. Very simply stated, this exhaust system is awesome.
