When General Motors unveiled the Duramax platform in 2001 little did they know they were introducing one of the most popular diesel pick-ups ever to roll of the assembly line. With that in mind, it comes as no surprise that MBRP produces the most popular single exhaust system for these trucks. The MBRP 4" Cool Duals exhaust system utilizes fully mandrel bent tubing, precision welds, and the most remarkably tuned muffler in the industry. This system is available in two different styles: XP Series and Installer Series.

The XP Series is the rugged and dependable series. Made of T409 stainless steel, it's designed and built to stand up to the hardest road conditions. MBRP is so sure that the XP Series has what it takes that they have backed it with an amazing lifetime warranty. That is absolutely the best warranty for a T409 system in the industry.

Last but not least is the Installer Series. Made of 100% heavy gauge aluminized steel the Installer Series is designed to provide the cost conscious consumer with the same high-quality design and craftsmanship as the other systems, but at a value price. This series is suitable for areas with moderate environmental conditions.

  • Gives your Sierra a great new look
  • Head turning sound
  • Available in two different styles
  • All hardware and installation instructions included

Lowered EGTs, increased fuel mileage, and improved throttle response have never been easier than with MBRP's direct bolt-on performance exhaust system and there is a price point for every budget. Whether looking for more pulling power or more horsepower for the drag strip...MBRP has you covered with this 4" system.
