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.

Just What I Was Looking For
Todd Sanford (Toledo, OH) 9/27/2011 9:24 PM
This exhaust system was exactly what I was looking for. Installed in about 3.5-4 hrs without a hoist on my 04 Ford Excursion. Sounds excellant and not to loud for when the wife has to drive it. 1 note was that I had to cut about 4" off the end for when I installed the tip, besides that everything looks and sounds great. Fit and finish of all parts was excellant and shipping was about 2-3 days. Matt at XDP was very helpful and knowledgeable of what he was selling not just a person at the end of the phone taking orders. That was very appreciated Thanks XDP
Great Product

I purchased this exhaust for my 06 f-350 Harley and I have to say I fell in love right away. With this and the MBRP 4 inch down pipe I am up 2-3 mpg, It's somewhat quiet when only lightly on it but when you jump on .... the sound is great. I also bought the cat delete pipe that I run on the truck during the summer months and it's a new animal but due to my job plowing snow in the winter I have to put the cat on to be somewhat quiet. I got to say, This system will give you the best of both worlds if you like it loud and fast or respectable with great sound, either way you win !!!!!

Great sound! I puchased this with and AFE Pro Stage 2 intake and together these both made a very good inproviement on the sound and running of my truck! Very simple to install it took about 45 minutes and I was taking my time. I combined these modes with and SCT 3015 flash programmer from XDP about 30 days later and I am amazed at the power increase and how well the truck runs with just the basic street tune!!!!!!
Great Sound!

I purchased this along with a Juice and Airaid Intake, and what a difference in power. The sound of this exhaust was exactly what I was looking for a little deeper, but still quiet enough at highway speeds that I don't really notice it's aftermarket.
