4" MBRP Exhaust For 01-10 Duramax 6.6L LB7, LLY, LBZ, LMM Aluminized No MufflerThis item can not be shipped to California due to being illegal for sale and use!The Best Systems Start with the Best Materials
Built from heavy duty aluminized steel, our 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.Built to Perform
You count on your truck to tow all of your gear to where you want it. With your 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 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 system gets exhaust out fast. Drop exhaust gas temperature by up to 200ºF and set the stage for all the performance you want. An exhaust system is the starting point to getting the most from cold air intakes, programmers, modules and downloaders.Easy Installation
These exhaust 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 we believe that appearance and sound is just as important. Every exhaust system has been specifically tuned to get the optimal sound from your Chevy Duramax 6.6L LB7/LLY/LBZ/LMM Diesel2001-2010 GMC Duramax 6.6L LB7/LLY/LBZ/LMM Diesel
07.5 - 10 Trucks:This product is intended for 01-07 Duramax Diesel’s, however this kit will fit 07.5-10 GM LMM Duramax pickups. The hanger locations on the LMM trucks are in the same locations as previous years trucks except one at the transmission (it’s there to hold the weightof the DPF and Cat) and one just behind it which is mounted to the frame (also meant to carry the weight of the DPF) and is no longer needed with this exhaust. If you are deleting the Cat and DPF, you will need a “Race Tuner” to eliminate the possibility of Limp Home Mode and Check Engine Lights.
