Honda® Rancher 420: IRS

HMF exhausts for the Honda Foreman Rancher IRS are available as full systems in the Performance and Titan series.  The HMF system replaces the bulky stock, one-piece system with a two-piece system consisting of a matched head pipe and silencer. 
Performance and Titan-XL systems pick up 3 hp and 3 ft-lbs of torque and are 2-4 dB louder than stock at idle.  Titan-QS systems gain 2 hp and 2 ft-lbs of torque and are only 1-2 dB louder than stock at idle.
