The Best Systems Start with the Best Materials
The MBRP S6032BLK 4" Black Series Filter-Back Exhaust System for your 2011-2015 GM 6.6L Duramax is built from heavy duty aluminized steel. Our Black Series performance exhaust systems offer a true "murdered out" style without compromising on quality and performance. With fully sealed seams to resist rust you can count on this system to really hold up. The black coat finish is specifically formulated to withstand the extreme heat and abrasive conditions an exhaust system is exposed to. 

Built to Perform
You count on your truck to tow all of your gear to where you want it. With your MBRP performance exhaust you can make that happen with an increase of up to +18HP & 28 ft-lbs. Give your truck more pulling power and much improved throttle response with an MBRP diesel exhaust system. MBRP systems are so much more efficient, it will be easy to see what your truck can really do.

Minimize Backpressure
The secret to getting more out of your diesel engine is to give it lots of cool, clean air. The only way that you can get fresh air in is to get the hot air out. From fully mandrel bent tubing to minimal bend degree angles, your MBRP performance system gets exhaust out fast. Drop exhaust gas temperatures and set the stage for all the performance you want. An MBRP performance exhaust system is the starting point to getting the most from cold air intakes, programmers, modules and downloaders. 

Easy Installation
MBRP systems are as much fun to install as to drive with on your truck. Bolt-on, no weld design makes installing this on your truck a no hassle project. Everything is direct fit to the OEM hangers and you get all the clamps and parts you will need, all in one box, no matter what configuration of truck you have.

Sound & Style
Performance is one thing but MBRP believes that appearance and sound are just as important. Every MBRP performance exhaust system has been specifically tuned to get the optimal sound from your pickup. With a stamped logo on the tip and MBRP's unmistakable styling, there's no question that you will have the hottest performance exhaust on the road.
