The Yamaha Raptor 350 is available as a Slip-On in the Performance and Competition exhausts. Each exhaust series Slip On system picks up 10-15% more horse power throughout the power curve. With T6061 Aluminum shells, each HMF exhaust system weighs substantially less that the stock exhaust. You can expect a 2-6dB increase in sound, however the Competition Inserts and HMF Quiet Core can lower that by 2-4dB.
Typically, fuel tuning is not required when installing an HMF Exhaust on this machine. However, other modifications to the machine may require the need for fuel tuning to ensure the machine runs properly, and there is no damage to the exhaust system. See the tuning settings below for possible tuning solutions or Contact Us for more information.
