RIVA Free Flow Exhaust Kit for Yamaha FX 140 & FX HO (MR-1) 2002-2008

RIVA Free Flow Exhaust Kit for Yamaha FX 140 & FX HO (MR-1) 2002-2008
Replaces the restrictive sound-suppression system between the waterbox and the hull outlet on MR-1 powered FX models. Less back-pressure, less detonation and a noticeable difference on the water. Easy install, race legal.
Good to know: aftermarket exhausts are louder than stock. Some harbours, lakes and marinas enforce noise limits, so check your local rules.
