MBRP 4 inch XP Series Down Pipe Back Kit for GM Duramax 2001-2007 6.6L (T409)
There are many, many things you can do to make power in your 2001-2007 Duramax-powered Chevy or GMC truck. Adding air, adding fuel, installing a tuner, and fitting a bigger turbo are all great modifications. But if you still have the original exhaust system, you can’t unlock the potential. This four-inch MBRP XP Series down-pipe back exhaust kit will let your Duramax-powered rig breathe free.
Made from durable sixteen gauge T409 stainless steel, this MBRP Duramax exhaust is backed with a lifetime warranty. Even on an otherwise stock engine, this kit can add up to 18 horsepower and 28 ft/lb of torque.
Better yet, it has a rich, mellow tone that sounds great even when cruising on the highway. This is really the first upgrade you should make to your truck. It’s an easy install, usually taking less than two hours, hanging from the original factory hangers.
