Built to Perform

You count on your truck to handle whatever you need it to do. With MBRP performance exhaust, you can make that happen with up to +18HP and 28 lbs-ft of more torque - not to mention lower EGTs. 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. From the spiral louvered high flow muffler to the fully mandrel bent tubing to 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.

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, they 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 their new stamped logo on the tip and unmistakable styling, there's no question that you have the hottest performance exhaust on the road - MBRP.
