Exhaust System

The LBZ exhaust category is for owners replacing rusted exhaust, adding a better-flowing system, or setting the truck up for towing. Cat-back systems, exhaust brakes, dual exhaust, and 4-inch kits all belong here.

Exhaust systems, cat-back kits, mufflers, exhaust brake parts, clamps, and related hardware fit 2006-2007 GM Duramax LBZ trucks. The right setup depends on sound preference, emissions equipment, and how often the truck tows.
