Improving the Performance of Your 6.6L LLY/LBZ/LMM GM Duramax Engine
Upgrading your diesel truck’s stock exhaust to an MBRP performance exhaust can add up to 18 horsepower with 28 ft/lb more torque. The 3” mandrel bent tubing used for this Down-Pipe Back Kit opens up the flow path allowing your engine to remove the hot air fast. The spiral-louvered high flow muffler was specifically designed to give your LLY/LBZ/LMM 6.6L Duramax trucks a rich, mellow sound.
Built for Easy Installation
Using all the factory mounts and OEM hangers, the Turn Down Series Down-Pipe Back Kit is a bolt-on exhaust unit. The estimated project time is 1.5-2 hours and that includes removing your stock exhaust. This kit is designed to fit any 2004.5, 2005, 2006, 2007, 2008, 2009 and 2010 GMC Sierra or Chevrolet Silverado 2500 or 3500 with a 6.6L LLY/LBZ/LMM GM Duramax engine.
