2001-2004 GM Duramax 6.6L LB7 Dual-Exit Exhaust Kits

The mighty 2001-2004 GM 6.6L Duramax LB7 builds may have quality sounding exhausts straight off the factory line, but the stock exhaust system doesn't have the menacing note your Sierra/Silverado truly deserves. Give your truck the powerful exhaust tones you want with any of the premium dual-exit cat-back systems we offer here at Alligator Performance! Many of these dual-exit kits include aggressively designed tips and two tailpipe configurations that compliment your truck's exterior styling by adding a custom look to your tough GM 2500/3500 truck. Once you've found the dual-exit kit that best suits your particular needs, pair it with an aftermarket cold air intake or performance tuner to unlock even more potential out of your rig.
