This marine-grade stainless steel exhaust riser system raises your exhaust outlet 15 inches—essential for boats with added weight, dinghies, bait tanks, or naturally low waterlines where the exhaust outlet sits dangerously close to the water surface. Water siphoning back into your exhaust system can rust turbocharger internals, damage cylinder heads, cause hydro lock, stick piston rings, and destroy valve seats—repairs that easily cost thousands. This riser prevents that damage before it starts. Fully hand TIG welded and jig fabricated for precision fit and durability. Includes heat-resistant exhaust lagging to protect surrounding components and an adjustable extended riser support rod for secure installation. Built tough for serious marine applications where reliability matters.
