The Story
The factory downpipe or turbo direct pipe in your 2011-2015 LML Duramax is highly restrictive and holds back your trucks power potential. Remove this restriction and install an AFE MACH Force XP 3" Stainless Down Pipe. This downpipe features a 3" 409 stainless steel mandrel bent tubing and heavy duty CNC machined flanges for a secure, leak free seal. This downpipe retains all factory sensors for trouble free operation. The MACH Force Down Pipe is finished off with a aerospace satin finish ceramic coating inside and out making it heat resistant up to 1600 degrees.
