BASSANI XHAUST B1 2:1 Exhaust - Black FLH-777B

If you're running a tuned big-displacement motor pushing 125+ horsepower, your stock exhaust is costing you power and efficiency. The Bassani B1 2:1 uses an extended inner collector and equal-length stepped headpipes to scavenge exhaust gases more effectively, translating to measurable gains in horsepower and throttle response. This is a purpose-built system for serious riders who demand performance without compromise.

The 4" straight-style muffler body keeps backpressure optimized while the black billet end cap with machined flutes delivers the aggressive aesthetics high-performance enthusiasts expect. Full-coverage heat shields protect you and your bike, while oxygen sensor port plugs handle both sensor and non-sensor applications. Built and assembled in the U.S.A.
