Starting from little more than a vision and an absolute passion for all things performance MBRP inc. is now at the forefront of performance exhaust technology.

Features:

• Fits 2001-07 GM Duramax Pickups
• Aluminized Steel Construction Mandrel bent tubing for maximum flow

What defines the Performance Series exhaust system is the muffler pipe that very cleanly takes place of the muffler delete which commonly comes on the PLM series. While allowing for more rumble than the OEM unit, this free flow muffler design allows for minimal restriction. Manufactured from an aluminized heavy-duty steel piping, protection from the elements is a worry of the past. In all, you will increase both horsepower, torque and improve fuel economy. Best of all, these exhausts are built in sectionals with bolt on hangers to allow for a graceful and simple install.
