The Best Systems Start with the Best Materials
The MBRP 4" PLM Series Downpipe-Back Exhaust System S6004PLM for your 2001-2007 GM 6.6L Duramax is built from heavy duty aluminized steel. The MBRP PLM Series 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 MBRP's 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 a 1 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 to 18 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.
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 temperatures 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 intake system, performance programmer, modules, downloaders, and other upgrades!
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 job. 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 they 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 an MBRP brand etched on the tip and their unmistakable styling, there's no question that you have the hottest exhaust on the road.
