Built to Perform

You count on your truck to handle whatever you need it to do. With MBRP you can make that happen with the horsepower, torque and lower EGTs that only a wide open, free flowing performance exhaust system can provide. More pulling power, improved throttle response, greater fuel efficiency, with an MBRP diesel performance exhaust you will be amazed at what your truck can 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. Thanks to MBRP muffler delete, the fully mandrel bent tubing and minimal bend degree angles, your MBRP performance system gets exhaust out fast. Drop exhaust gas temperature by up to 200°F 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 installation a no hassle one and a half to two hour 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 at MBRP we believe 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 our stamped logo on the tip and our unmistakable styling, there's no question that you have the hottest performance exhaust on the road - MBRP.
