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.

MBRP 5" - 2001 Dodge 3500

Got the 5" exhaust installed with the help of a couple friends. Getting the old stock system off was the hardest, but this new MBRP system went on easy and sounds great. Box was torn upon delivery, almost like its too heavy for the way they pack it - only two of the pipes had minor dents in the ends, but easy fix.

sorry guys but what a crude piece of crap! like everyone else the box was torn open and all ends had to be hammered,even the bag with the clamps - one manifold bolt and one clamp missing.then the flange where it hooks up to the manifold was to large so i had to cut off the stock one and weld that on,then the length wasn't right for my reg cab so i had to cut another piece to make it fit,by this time I was really pissed!! earlier this year I bought a 4 inch t 304 stainless from MBRP and that was perfect in every way, but the sound was a bit mellow.OK now some good news the 5 inch sounds great and the 8 inch tip looks really cool but I'll never buy another one like this again.

Great buy! The sound is awesome a breeze to install little bit of a job removing the old system,but well worth the fight. This is my first upgrade of many and am well pleased with this product.

I cant believe how easy it was to install a 5" exhaust on my truck. I thought it would take all day, but was done in less than a hour, without a lift. Nice mandrel bends, great fit, sounds awsome. I couldnt be happier!

I love this thing, it sounds awesome. Its my first step in upgrading my rig. Just like everyone else almost all of the ends were bent, so I had to hammer them all to get them to fit. The only thing was when putting it on you need to make sure you take that very front hanger mount off to connect it to the turbo! I did not read the directions that well and it took me almost 3hrs just trying to get that together. Besides that if I would of read them right it would have only taken like 30 min to put it on. Now taking it off is a different story. I would suggest an air ratchet and air cutter to cut it off. It should only take an hour and a half if you have the right tools. Great exhaust though, I only heard good things about it and thats why I bought it. Again its just awesome! BUY IT NOW!!!
