The Best Systems Start with the Best Materials

Built from heavy duty aluminized steel our Installer Series performance exhaust systems offer a value price without compromising on the quality built into every component. While the seams are a major point of rust through with some budget systems our fully sealed tubing adds years to your system. Constructed to the same specifications as our top of the line Pro Series we back this line with an industry leading 3 Year 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.

Install. First pipe that connects to down pipe is almost a foot off from connecting to hanger. Second pipe back doesn't curve around cross member quite right and had to bed hanger up at this point to get the first pipe up off the frame. Tried different variations with the pipe included and no matter how I did it it just didn't fit together quite right. Seems like most of the pipe is in a bind all the way back to the tailpipe. There is no need for a tip unless you want to cut 12 inches off the tailpipe. Granted this is not their top of the line pipe but I think it should still fit under it like a glove. It is hard to beat for the price though.

Sounds good! Has a good throaty rumble, turbo spools faster, and top end increased incredibly! Lost a little bottom end, and it was a little tough working around the shocks and part of the frame where the front pipe connects to the rest of the exhaust, but it all ended up falling into place. Overall, good product! Thanks XDP!!!

Easy to install, about 3 to 4 hours for me. Had to cut in front of the cat to get the stock exhaust off no other way to get the cat out. A jack under the bumper for the back half works well. 4" front cat delete pipe not sure 5" is needed but not too loud looks and sounds great, price is good!
