The exhaust has a removable db killer (noise restrictor) for racing use. Removing the DB Killer is ILLEGAL, and the customer assumes responsibility if they use the motorcycle only on circuits, without bags, turn signals, a license plate holder, or other parts that would conflict with the different exhaust gas angle after conversion to the racing version. Misuse on public roads will void the product warranty, and any refund request will be rejected.
The warranty is valid for two years from the date of purchase, with the right to repair by returning the product to the GPR factory or the nearest official distributor at the customer's expense.
GPR will not provide a new silencer but will repair the original silencer. The customer must agree to reinstall the original exhaust or wait the standard repair time.
