Burns Stainless is excited to introduce the “No Holds Barred” (NhB) Exhaust for Harley-Davidson

“For years we have been working with many of the world’s finest big-twin tuners helping them win races, set records and make big power in dyno shootouts with our exhaust builds,” comments Vince Roman, Technical Director at Burns Stainless. “It became apparent that there were not any well-engineered stainless aftermarket systems available for these big engines, so we decided to offer a 2-into-1 system incorporating the famous Burns merge collector.”

Full system exhaust including mufflers
Mandrel bent stainless steel tubing
100% Argon back-purged TIG welding for high strength and precision fitment fitment
Primary length is adjustable to optimize torque and power and includes an adaptable header mount
Systems are constructed from ASTM269 304 stainless steel tubing for best combination of weight savings and durability
Made in the USA

Additional Options

Standard primary length is 33 inches - call for custom length

Proper Port Fitting Design

Due to the high velocity at the exhaust port, it is imperative that the flow be unobstructed. We have seen as much as a 5% loss of power for poorly matched headers and ports. To ensure proper flow, Burns has designed port fittings that properly align the exhaust header to the port. Also, the exacting dimensions of the fitting allows for better, more repeatable fabrication ensuring a proper fit on the motorcycle. On the Milwaukee 8 system, we have engineered a CNC machined fitting to improve the fitment of the pipes.

Stepped Primaries

By keeping the header size close to the exhaust port size, exhaust gas velocity is kept high at the port reducing the possibility of reversion. This is especially important with the unequal firing impulses inherent to the V-Twin single pin crank arrangement. Enlarging the tube with stepped pipes ensures that wall drag losses are minimized keeping the exhaust potential available for maximum power but also allowing for broad power band.

Collector Design

The 2-into-one collector helps minimize exhaust reversion while helping to scavenge the exhaust cylinder during each exhaust cycle. The efficient scavenging of the cylinder during the exhaust and overlap period allows for the maximum amount of air and fuel in the cylinder assuring maximum power.

Muffler

The Burns megaphone muffler provides the Pro-Stock appearance of the exhaust while maximizing performance and reducing the sound of the exhaust. The deep, mellow sound is a by product of the specially designed core perforations.

The small holes provide effective damping of sound waves while allowing for a smooth bore minimizing drag losses and improving power output.

Burns Stainless is pleased to announce the “No holds Barred” (NhB) exhaust for the Harley Davidson Milaukee-8 Softail line. The Burns exhaust has quickly become the “pipe” of choice for the premier tuners and racers in the country. The huge success of the NhB exhaust for the Harley baggers has prompted us to expand to the new generation of Harley sport bikes. The exhaust will fit the full line of softail models including the radical FXDR. The exhaust retains the signature reverse cone megaphone muffler. The exhaust features:
