Built to Perform
You count on your truck to tow all of your gear to where you want it. With your MBRPinc performance exhaust you can make that happen with up to 18 HP more horsepower and 28 ft/lb more torque. Give your truck more pulling power and much improved throttle response with an MBRPinc diesel exhaust system. Our 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 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 degrees farenheit 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
MBRPinc 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 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 is just as important. Every MBRP performance exhaust system has been specifically tuned to get the optimal sound from your pickup. With our MBRP brand etched on the tips and our unmistakable styling, there's no question that you have the hottest exhaust on the road - MBRP.
