This system from MBRP offers an affordable, no-nonsense path to making more power with your ’01 to ’07 Duramax. The 4-inch diameter, downpipe-back system is made from aluminized steel, features a single, side exit, and comes with a two-piece tailpipe, bolt-on hangers, and all installation hardware.

Note that this system can be installed on LMM model Chevy and GMC 2500 and 3500’s (’07.5-‘10), but requires a hanger modification near the transmission mount in order to work.
