VANCE & HINES - 2-into-2 Big Radius Exhaust - Dyna 91-05 Chrome

Showcase sculptural curves and radical Custom style with the essential Vance & Hines Big Radius Full Exhaust System. Instantly recognizable with its profiled tubes oriented towards the ground and magnificent scalloped cutouts, this high-end exhaust radically redefines the silhouette and temperament of the Harley-Davidson Dyna (1991-2005) generation.

Assertive Custom Style and Maximum Performance

The Big Radius system combines a fluid, aerodynamic design with cutting-edge engineering designed to extract all the power from your Evolution or Twin Cam engine. By optimizing gas extraction efficiency, this line offers an immediate mechanical gain:

• Increased power and torque: Generous mid-range torque for strong acceleration and instant responsiveness.

• The Hot-Rod sound signature: A unique, deep, cavernous, and particularly powerful rumble that intensifies very satisfyingly when you open the throttle.

Full-Coverage Anti-Bluing Heat Shields

To ensure your exhaust system retains its sparkling chrome appearance like new, the system incorporates 2-1/2" (6.35 cm) outer diameter heat shields precision plasma cut. Offering full coverage along the entire length of the headers and mufflers, these thermal shields perfectly insulate the inner steel from heat, virtually eliminating any risk of visible bluing or yellowing.
