MBRP 4” Pro Series Cat Back Single Exhaust System Kit for GM Duramax 6.6L (T304)
MBRP designs their products with the phrase, “The best system starts with the best materials” in mind. This Pro Series Cat Back Exhaust System Kit is made from T304 steel offering a value price without compromising the quality. Plus, the MBRP Pro Series exhausts come with a Lifetime Warranty.
Improving the Performance of Your 6.6L 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 4” T304, mandrel bent tubing used for this system 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 6.6L Duramax truck a rich, mellow sound.
Built for Easy Installation
Using all the factory mounts and OEM hangers, the Pro Series Cat Back Single Exhaust System 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 2006 and 2007 GMC Sierra or Chevy Silverado 2500/3500 with a 6.6L GM Duramax engine. MBRP includes all the clamps and parts you need for easy installation whether your diesel truck has a Crew Cab, Extended Cab, short or long bed.
