MBRP "Smokers" Stack System
Some people love stacks because of the awesome rumble that they make cruising down the street. For others it's the big rig look of stacks crowning their truck. Who's right - who cares? You get both with MBRP's SMOKERS. Personalize your ride with our wide range of stack designs. Stack tip sold separately.

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.

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 unmistakable styling, there's no question that you have the hottest exhaust on the road - MBRP.

Great system

I have a 1995 dodge 2500. Install wasn't bad hardest part was getting the old exhuast of the turbo. Great system had no problems with the pipe but I have a regualr cab. Only downside was you have to cut through your bed support. All in all awesome power and sound went from 17 highway to 19.5 with just the exhaust

Fkex pipe is junk and can be bought anywhere!!!!! Should have came with a better design part and some exhaust hangers to just weld or bolt in place. Lastley, make shure people know that if you have a fuel tank, or a tool box that their so no room at all extend the pipe back. You just have to go buy a longer length. My truck has 1638ft. lbs torque, and 947 hp at the wheel, so the pressure does make for a new design for the flex pipe extension.
nice but not long enough

Nice product but the flex pipe isnt long enough but when its done great sound and smoke.
Nice kit but installing..

nice exhaust system except for the fact that the flex pipe isn't the greatest engineered part. Secondly having a quad cab i changed the design of the kit but taking the last part that comes out of the bed and put it underneath so i could get the extra length. But once i finished it was good and came out how i wanted with the 36" stack sitting at cab level. Sounds sweet too!!

This system sounds and performs great. Everything that is needed is included in the kit. The only reason for 4 stars, is that unless you want to cut a hole through your forward most bed support, (if you own a 2nd gen quad cab), you'll need to use every inch of pipe that you can. But in the end, it is well worth it.
