Burns Stainless NhB 2-Into-1 Exhaust for Harley-Davidson M8 Touring
The Burns Stainless NhB 2-Into-1 Exhaust is engineered for riders who demand maximum performance, precision fitment, and premium materials. As a result, this exhaust system improves horsepower, torque, and throttle response while maintaining excellent durability for long-term use.
In addition, Burns builds each system using advanced exhaust design principles developed through racing and real-world testing. Because of this, the exhaust delivers strong mid-range power and impressive top-end performance without sacrificing rideability.
Performance-Driven Design
First, the stepped primary tubes increase exhaust gas velocity and reduce reversion. Therefore, the engine scavenges more efficiently throughout the RPM range. In particular, V-Twin engines benefit from this layout due to their uneven firing pulses.
Meanwhile, the 2-into-1 collector merges exhaust flow smoothly and evenly. As a result, cylinder evacuation improves and power delivery becomes more consistent.
Premium Materials and Construction
To begin with, Burns uses mandrel-bent ASTM 304 stainless steel tubing for strength and corrosion resistance. At the same time, the consistent internal diameter supports optimal exhaust flow.
Additionally, skilled fabricators complete every joint using 100% argon back-purged TIG welding. Because of this, the system achieves strong welds, precise alignment, and long-term reliability.
Finally, each exhaust is hand-built in the USA and designed to handle aggressive riding and high-output engine combinations.
Megaphone Muffler Technology
Notably, the NhB system includes a reverse-cone megaphone muffler that enhances exhaust flow while controlling sound levels. For example, the perforated internal core smooths exhaust pulses and supports higher horsepower output.
As a result, riders experience a deep, aggressive tone without excessive harshness or unwanted drone.
Adjustable and Tunable Fitment
Furthermore, the exhaust features adjustable primary lengths, which allow proper tuning for different engine combinations. In turn, this helps riders fine-tune torque and power delivery.
Likewise, a custom header mounting system improves stability and ensures consistent alignment on the motorcycle. At the same time, precision-machined exhaust port flanges minimize leaks and maintain smooth exhaust flow from the cylinder head.
Available Configurations
For example, choose the Standard version for stock or mildly modified engines. On the other hand, riders running large-displacement or high-output builds may prefer the VST (Velocity Stack Technology) version.
Specifically, the VST configuration is recommended for engines in the 121–135ci range. As a result, the powerband expands and low-RPM flat spots are reduced.
