The HMF Performance Series has a specially designed, unrestricted core that allows the exhaust to increase power evenly throughout the entire power curve. It also features the signature HMF sound with industry-leading end cap and color options, giving you a completely custom look.

• The Performance Series uses a 2 1/8" non-restrictive core for maximum flow.
• Depending on the model, you can expect a 4-6 dB increase over stock.
• The exhaust shell is made of T6061 Aluminum that weighs substantially less than stock.
• USFS Approved: All HMF offroad exhausts come with a USFS approved spark arrester.
• Two Year Warranty: HMF Engineering Inc. warranties all exhaust systems for two years from the date of purchase for all manufacturing defects.
