Chevy Silverado/GMC Sierra & Silverado SS Exhaust System
Billy Boat Performance Exhaust has them available as either a Dual-back (split rear system) and featuring 4.5" Elliptical tips or as a True-dual (side exit system) featuring 3.5" Round tips. Both systems feature fully polished mufflers and tips, high quality craftsmanship and 100% T-304 stainless steel construction. Crafted in-house using B&B's proprietary muffler design and mandrel bending resulted in the increased horsepower and torque as well as improved flow and fuel efficiency. In addition to improving the performance of the SS and Denali pickup, the B&B system also provides a deeper more aggressive tone without annoying interior resonation.
