Here you get a good replacement exhaust for the original.
The exhaust is primarily designed for mounting on models with 10 inch wheels, but can, for example, be modified with spacers or spacers, adapted to 12 and 13 inch models.
NOTE: Spacers or spacers are a prerequisite for creating space for the exhaust to go free of the rear wheel, on models with wider tires than 10 inches.
Note: The exhaust is delivered without bolts for the suspension, the exhaust is unrestricted and is therefore not legal to use on public roads.
