B1 2:1 Exhaust

The Bassani Road Rage II B1 Power 2:1 is built specifically for tuned, high horsepower motors, using an extended inner collector.

The B1 is not a general purpose system, and the name signals it: this is the Road Rage II built for motors that have already been tuned for high horsepower. The extended inner collector is the reason. It is sized to organize flow from an engine making real power, which is exactly the airflow a stock motor cannot produce. On a built motor it is right; on a stock one it is more collector than the engine can use.

How the B1 Power System Is Built

A unique extended inner collector maximizes performance for high output applications. The 4" straight style performance muffler body carries a 2-1/2" by 16-1/2" baffle and a black billet end cap with contrasting machined flutes. Oxygen sensor port plugs are included for non-sensor applications. Made in the USA.

Before You Order the B1

⚠️ VERIFY that your motor is tuned for high horsepower before ordering, since this system is designed for built engines rather than stock ones.

⚠️ VERIFY street legality and emissions compliance for your state and model year before purchase. Most aftermarket performance exhaust systems are intended for closed course competition use and are not certified for street use in all jurisdictions. Plan on retuning the bike after installation.
