    Exhaust Riser Kits


Click HERE to view the Exhaust Component Look-up Chart.

These kits raise the level of the exhaust elbow to help prevent water from back-flowing
into the engine through the exhaust. Exhaust height is critical and special care must be taken
during engine installation to adhere to all factory recommendations.

Kits are sold "per engine". One kit will be enough for one engine unless you want to stack kits
for up to a maximum of 9" over normal elbow height.

Kits include all gaskets and mounting hardware. Some include accessory mounting plates if required.

You need to know what engine you have and what style of exhaust you have before ordering your kit(s).
You also need to know if your engine is raw water cooled or if it is closed (fresh water) cooled.
We no longer sell the rectangular kits for the older log-style manifolds.
