BURNS STAINLESS NhB Exhaust for M8 Softails

BURNS STAINLESS NhB Exhaust for M8 Softails

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

** Our systems are popular right now. Please allow us 3 weeks to build your exhaust.**

“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.”

 

System Styles:

M8 Softail- The NhB exhaust for the M8 Softail, initially crafted for the HD FXDRS, is compatible with most Softail models featuring forward controls. The system is a Stepped Design: 2", to 2-1/8", to 2-1/4" to a 3" Collector and reverse cone megaphone muffler. The HD FXDRS, known for its aggressive performance and distinctive styling, sets a high standard for power and agility. With the NhB exhaust, your Softail will not only match this performance but also enhance its unique sound and appearance.

Low Rider S (LWRS)- The LWRS style, created specifically for the Low Rider S model with HD mid-controls, also fits ST models with side bags. An optional adapter is required (not available from Burns Stainless). The system is a Stepped Design: 2", to 2-1/8", to 2-1/4" to a 3" Collector and reverse cone megaphone muffler. The Low Rider S is celebrated for its raw power, precision handling, and iconic design, making it a favorite among Harley-Davidson enthusiasts. With the LWRS style, you can maintain the authentic look and feel of the Low Rider S while accommodating additional storage needs on ST models.

 

Features:

  • Full system exhaust including mufflers
  • Stepped Design: 2", to 2-1/8", to 2-1/4" to a 3" Collector and reverse cone megaphone muffler.
  • Mandrel bent stainless steel tubing
  • 100% Argon back-purged TIG welding for high strength and precision 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
  • Standard primary length is 33 inches.
  • Product comes with support bracket for reverse cone megaphone muffler.
  • Product ships standard with both 18mm and 12mm O2 sensor bungs.

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.

 

Black Ceramic Coating Disclaimer:

Due to the extreme operating conditions associated with high-performance engine builds, Burns Stainless ceramic-coated exhaust systems are not warrantied against coating discoloration, flaking, or failure resulting from excessive exhaust temperatures. These issues are typically caused by improper air/fuel ratios, insufficient tuning, or other build-related factors beyond our control. Customers assume full responsibility for ensuring their engines are tuned within safe operating parameters. Coating integrity is not covered under warranty when used in racing or high-performance applications.
