2001-04 6.6L LB7 GM Duramax Exhaust Components

Your 2001-04 6.6L LB7 GM Duramax comes with a 3.5" turbo back exhaust from the factory, equipped with a catalytic converter and a fairly "thick" muffler.  The factory turbo direct pipe is considered 3.5", but is more a flattened out exhaust pipe for factory clearance issues.  As long as you're not going hog wild on power, the factory exhaust size and turbo direct pipe are adequate.  However, if you want to add a distintive look or sound to your Duramax, or try to optimize exhaust flow without spending a lot of money, this can be done by adding any variety of tips or aftermarket mufflers to the truck.  We carry 4", 5", 6", 7" and even 8" tips from Diamond Eye, Silverline, MBRP and Magnaflow.  If you are looking for a muffler we carry Aeroturbine, Silverline, Hushpower and Diamond Eye.  Give us a call, we'll be happy to help you decide which muffler is right for your 6.6L LB7.
