This is a great fix for any turboed 2007- 2016 Ski-Doo snowmobile.
this fixes the bursting exhaust bellows when a turbo is added to the system.
Letting the exhaust valves work properly and not bleed to atmosphere.
Also fixes low end bog due to exhaust valves not being able to close when the motor is in vacuum state.
