The Dual System mufflers use the 2-1/8" Performance Series straight cores. These replace the original restrictive mufflers and maximize the exhaust flow for better overal performance. These systems feature the trademark HMF sound with color and end cap options.

The Performance Series from HMF has been the staple of the brand since its origin. This exhaust system has the capability of generating an even increase in horse power and torque while distributing an aggressive deep sound.
The Performance Series is assembled on an durable 6063-T6 aluminum alloy shell, with magnesium and silicon as the alloying elements. A high-temp powder coat can be applied for a completely custom look.
Featuring a 2 1/8" unrestricted core, the Performance Series core has a special hole pattern that allows the exhaust system to increase power evenly throughout the RPM range.
This is the feature that sets HMF apart from any other after-market exhaust. The sound coming from the Performance Series can be described as a deep aggressive, angry tone.
HMF is the leader in custom exhaust and end cap colors. Depending on the vehicle you're riding, you can select from endless color and end cap options.
