Bassani Road Rage B4 Exhaust For Harley Touring 1995-2016

Bassani Road Rage B4: Maximum Horsepower for the Classic Bagger

The Bassani Road Rage B4 is not your average 2-into-1 exhaust; it is a specialized performance tool designed for 1995-2016 Harley-Davidson Touring models that have been built to run. While the standard Road Rage is excellent for stock or mild engines, the “B4” designation indicates a larger muffler body and specifically tuned baffles meant to handle the high exhaust volume of 103ci, 110ci, and big-bore Twin Cam engines. Compatible with the Road Glide, Street Glide, and Road King, this system transforms your Touring bike from a mild-mannered cruiser into a high-performance machine with a powerband that feels endless. By utilizing a single-sided megaphone design, Bassani significantly reduces the weight of your exhaust system while providing the best ground clearance in its class.

Stepped Headers and Competition Scavenging

The secret to the B4’s dominance lies in its stepped header technology. The pipes begin at 1-3/4 inches at the cylinder head and step up to 1-7/8 inches before entering the collector. This design maintains high exhaust gas velocity at lower RPMs to preserve torque, while providing the necessary volume for massive horsepower gains at the top end. The headers merge into a high-flow collector that uses scavenging pulses to “pull” exhaust gases out of the combustion chamber more efficiently than any dual-pipe setup. The result is a smooth, linear power delivery that eliminates the “torque dip” commonly found in less-sophisticated systems. The B4 is the ideal foundation for riders who have installed performance cams, high-flow heads, or increased compression.

Expert Tuning & Installation Advice

As V-Twin performance specialists, we consider the Road Rage B4 to be one of the most “raw” and authoritative pipes on the market. Pro Tip: The B4 is significantly louder than a standard slip-on or a standard 2-into-1. It produces a crisp, mechanical bark that is unmistakably race-inspired. Tuning Note: Because this system flows so much air, a high-quality fuel tuner like the Vance & Hines Fuelpak FP3 or Dynojet Power Vision is mandatory. Without a proper tune, a high-flow engine running the B4 will run dangerously lean, leading to excessive heat and popping on deceleration. Installation Note: When installing on 1995-2016 models, ensure you use new flat exhaust gaskets rather than the tapered style to ensure the stepped headers seat perfectly against the head port. Always clean the pipes with rubbing alcohol before the first start to prevent fingerprints from becoming permanent marks in the finish.

The Ultimate Sound of Power

The sound of the Bassani B4 is what legends are made of. At idle, it delivers a deep, percussive “thump.” Once you crack the throttle, it transforms into a thunderous, high-velocity roar that echoes the performance baggers seen on the race track. Every Bassani system is 100% Made in the USA, ensuring that the welds and chrome are of the highest quality. For the 1995-2016 Touring rider who refuses to compromise on performance and wants the loudest, deepest, and most powerful 2-into-1 on the road, the Bassani Road Rage B4 is the definitive choice.

Fitment Note: Fits all 1995-2016 Touring models. Not compatible with Trike models. Some models may require a frame-mounted spacer if using aftermarket extended floorboards.
