2001-2004 GM HD THREE-INCH 304 STAINLESS STEEL DOWN PIPES (117000400)

Description

The factory downpipe is two pieces of formed sheet metal welded into an oval, with a sharp transition right off the turbine flange that chokes exhaust flow. Replace it with PPE's Free-Flow 304 stainless steel downpipe: a robust half-inch turbine flange, a CNC-machined lower flange, and smooth round transitions for unobstructed flow. A woven titanium heat sleeve insulates the pipe to lower engine bay temperatures.
