The Best Systems Start with the Best Materials

MBRP's XP Series is the performance exhaust of choice for the enthusiast who needs a system that can take anything that the road throws at it. This system's rugged sixteen gauge T409 construction can be counted on to withstand everything from salt to rocks, tar to grime. We have had such success with this line that we back it with a Lifetime Warranty.
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 up to18 HP more horsepower and 28 ft/lb more torque. Give your truck more pulling power and much improved throttle response with an MBRP 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 200ºF 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 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 tip and our unmistakable styling, there's no question that you have the hottest exhaust on the road - MBRP.

I have been running this exhaust for about a year now and it has been great. I have put a lot of exhaust kits on in the pass and hands down this kit was the easyest and cleanest i have every put on. This monster 5 inch pipe makes amazing sound and looks great well worth the money.
5 inch exhaust

I went from 2 stacks to this, and the difference between the two is incredible. When i put this exhaust on i instantly loved it. Sounds great, has a real deep tone to it. The throttle response was hella better. Idk if it as a whole lot of hp or any. but it Rips now. I would buy this again. Price is ok, ofc we all want to buy things cheap.

Took 3 months for system to arrive problems with mbrp tooling. xdp made the situation right for me and kept me informed on the problem. simple to install 2 guys half and hour. the old exhaust was harder to remove. love the sound and does not have the drone when cruising down the freeway that I have heard with some systems. I would recommend this product to others.
Awsome product
