H.S.I. 2.5" rear exhaust long exhaust hose specifically designed for use with skis running lay down exhaust systems.
No more wasting a OEM style SJ exhaust hose or having to use an aluminum pipe with 2 short couplers. The long silicone exhaust hose also helps reduce noise compared to running a long aluminum tube.
Works with Yamaha based hulls using a BUN, RRP, TNT, or Power Factor exhaust system. *You may need another angled coupling from water box to hose if the water box has an angle to it.
High temp and high quality silicone that has been thoroughly tested.
