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" single exhaust system utilizes fully mandrel bent tubing, precision welds, and the most remarkably tuned muffler in the industry. This system is available in three different styles: Pro Series, XP Series, and Installer Series.
The Pro Series is for the serious performance enthusiast who demands the best of the best. For your vehicle there is no better stainless steel than T304 and no better system than the MBRP Pro Series. With the highest chromium and nickel content of any exhaust, this is simply the best system money can buy. This system is also backed by the MBRP lifetime warranty.
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.
