Burns Stainless NhB Exhaust for Harley-Davidson M8 Baggers
Take your Milwaukee-Eight touring bike to the next level with the Burns Stainless NhB Exhaust for M8 Baggers. Designed for serious performance enthusiasts, racers, and high-horsepower Harley-Davidson builds, the No Holds Barred (NhB) exhaust system combines advanced exhaust engineering, premium stainless-steel construction, and race-proven performance technology to deliver massive horsepower gains, improved throttle response, and an aggressive deep exhaust tone.
Built specifically for Harley-Davidson M8 Touring and Bagger models, the Burns NhB exhaust features proprietary Burns merge collector technology and stepped primary tubing engineered to maximize exhaust scavenging, minimize reversion, and broaden the usable powerband. Riders can choose between the Velocity Scavenge Technology (VsT) system for 121–135 cubic-inch builds or the Burns Big Momma (BbM) system for extreme 135+ cubic-inch high-rpm race applications. The VsT configuration uses 1-7/8”, 2”, and 2-1/8” stepped primaries flowing into a 3” collector and reverse cone megaphone muffler, while the BbM system steps up to massive 2”, 2-1/8”, and 2-1/4” primaries for maximum top-end horsepower.

Manufactured from premium ASTM269 304 stainless steel tubing, every Burns NhB exhaust is mandrel bent and 100% Argon back-purged TIG welded for superior strength, lightweight durability, corrosion resistance, and precise fitment. The floating design incorporates Burns’ exclusive CNC-machined stub system, oversized flanges, and aerospace locking hardware to ensure reliability under extreme performance conditions.

Riders seeking a race-inspired Harley bagger exhaust system with dyno-proven horsepower gains, handcrafted quality, and professional-level engineering consistently choose Burns Stainless as the benchmark in M8 performance exhaust technology. Burns’ proprietary X-Design development process—refined through years of professional motorsports competition and dyno testing—helps optimize torque, throttle response, and top-end power across the RPM range.
