Expect strong power throughout the entire RPM range with improved throttle response and a more refined exhaust note.
Constructed in the USA from mandrel-bent, high-grade 304 stainless steel, this exhaust is built for durability and performance.
The TIG welded 6061 aluminum silencer features a carbon fiber end cap, providing a clean look while reducing overall weight compared to the stock exhaust system.
