Exhaust pipe made by bending aluminum.
Contributes to approximately 50% (grams) lighter weight and lower center of gravity compared to the genuine rubber tube.
Unlike genuine tubes, there is no expansion due to exhaust temperature, reducing trouble.
Carburetor maintenance is more efficient because the pipes are connected to the bottom of the carburetor.
If you use the T-bolt clamp [Product number: JL0250], there is no need to worry about it coming off.
The joint uses a silicone hose that is highly heat resistant, pressure resistant, ozone resistant, and resistant to deterioration.
