Description

The Best Systems Start with the Best Materials
The MBRP 4" Black Series Downpipe-Back Exhaust System S6004BLK is built for your 2001-2007 GM 6.6L Duramax from heavy duty, black coated aluminized steel. The MBRP Black Series performance exhaust systems offer a true "murdered out" style without compromising on quality and performance. With fully sealed seams to resist rust you can count on this system to really hold up. The black coat finish is specifically formulated to withstand the extreme heat and abrasive conditions an exhaust system is exposed to. 

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 and 28 lb-ft more torque. Give your truck more pulling power and much improved throttle response with an MBRP diesel exhaust system.  

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 200 degrees 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. A bolt-on, no weld design makes installing this on your truck a no hassle 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, 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 will have the hottest exhaust on the road - MBRP.

Can I get the MBRP 4" Black downpipe back as a straight pipe without muffler?

Unfortunately, the MBRP Black Series are only sold with the muffler. To eliminate the muffler you must purchase an MBRP muffler delete pipe separately.
