Diamondback 2-1 - Guardian Black finish

Diamondback - Guardian Black

S&S was building Performance Baggers long before it was called that and our focus has always been on making big power! The Diamondback two into one exhaust is a perfect example of our commitment to true performance. Beginning with a stepped header for maximum flow and a merged collector specifically engineered to prevent exhaust gas reversion, this system wraps up with a 4" full stainless muffler that ends before the rear axle. Diamondback is not for your Daddy's bagger, but purpose built to make big power and sound, excellent cornering clearance and just the right look. Clearanced for tall shocks and available in brushed stainless or Guardian Black.
