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.

Great product fit perfectly on my 03 cummins 4x4 4 door short bed with one cut of the center pipe to fit short bed. Installation was pretty easy by myself. Two people would have been perfect. Had a stock straight pipe prior to this system and it's substantially quieter but still sounds good. Tip looks awesome.

I have a '98 3500, 4wd, 5spd, quad cab that I installed this exhaust on. This is one of the best fitting exhausts that I have put on a truck. No headaches with the install!! Looks great w/tip! Plan on installing another one shortly on an '03.
This Exhaust is Outstanding!

I purchased this system during the memorial day sale this summer. First of all the FREE shipping is AWESOME! The exhaust got to my house in less thsn a week and I live in California. The price was $75.00 cheaper than I could have gotten it in town. The performance is incredible! Towing a 35 foot toyhauler loaded with quads and gear it improved the mileage on my 03' Dodge 2500 by 1.5 MPG!! It really works! Thank you Xtreme Diesel! Tony.
Great Product

I have a 03' 3500 4x4 dually. This system was easy to install. Bolted on with no headaches. The hardest thing is getting the stock exhaust off of the pickup. You better have a torch to heat the stock components, an assistant to help pull the pipes apart, and a lot of patience to not damage the stock system. Highly recommended product, sounds great, and performs much better than stock.
