The all new redesigned Evolution muffler shape paired with a sleek end cap offers all the performance you expect with great style and that legendary Hindle sound! The all new EVO muffler now uses the best high temperature packing in the industry. Packing that lasts up 3-4 times longer than standard fiberglass means less maintenance and consistent power all season long. Spend less time repacking mufflers and more time riding! Mufflers are available in Stainless Steel, Black Ceramic, Titanium or Carbon Fiber for most systems.
