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 to 18 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.
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 SMOKERS™ 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 SMOKERS™ exhaust system is the starting point to getting the most from cold air intakes, programmers, modules and downloaders.
MBRP SMOKERS™ are as much fun to install as to drive with on your truck. They are designed to make installing a system onto your truck a no weld, no hassle two to two and a half 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.
