The Duramax has a refined toughness to it. MBRP Inc. has left the refined part to General Motors, and added extra toughness. The Duramax makes big power gains with this high flow 4" mandrel bent T-304 Stainless Steel exhaust system. Each system is a direct bolt on application and is manufactured as a full 4" system all the way back to the 5" diameter exhaust tip (included with this system).  Lower EGT (exhaust gas temperature), improved fuel economy along with more towing power are just some of the added benefits of having this system installed on the Duramax.

For over fifteen years MBRP inc. has been delivering performance enthusiasts the most in power, the most in product quality and the most in customer responsiveness.  Starting from little more than a vision and an absolute passion for all things performance MBRP inc. is now at the forefront of performance exhaust technology. Marshalling over ten decades of manufacturing and marketing expertise between them, the MBRP design team developed a line of performance diesel exhaust products that has made the rest of the industry take notice, and rush to catch up.

Most recently MBRP Inc. has achieved something special for the sports truck enthusiast. The new sport line brings to the gasoline-powered vehicle the same perfect blend of style and toughness that diesel light truck owners have come to expect from MBRP. The line features a unique flow through muffler originally developed to increase the performance of thousand horsepower off shore marine engines. The result is a muffler that generates a deeper, mellow sound, improved performance numbers and cooler operating temperatures.  And for everyone, toll free technical support that can talk even the least experienced installer through the process. For the future, MBRP inc. is determined to provide the highest fill rates in the industry, offer the most complete line of exhaust for diesel and sports truck enthusiasts and to be always pushing upward the definition of performance.

This exhaust system fits the 01-05 Chevy/GMC 2500/3500 with the Duramax diesel engine.  Don't forget - our price INCLUDES SHIPPING!
