No structural modifications to the motorcycle are required to install this product for use in its approved version. We recommend reading the instructions included in the package or viewing the tutorials at www.gpr.it and on YouTube.
For online purchases, the warranty must be activated by emailing the special coupon stamped by the installation workshop to [email protected]. For purchases at physical stores, the shop stamp is sufficient. The exhaust has a removable db-killer (noise restrictor) for racing use. Removing the db-killer is not ONLY illegal; the customer also assumes responsibility for using the motorcycle only on circuits, without bags, turn signals, a number plate holder, or other parts that could interfere with the different exhaust gas angle after conversion to the racing version. Misuse of this setup 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 and entitles the customer to repairs at the GPR factory or the nearest official distributor, at the customer's expense.
GPR cannot provide a new silencer as a replacement while the original is being repaired. The customer must agree to refit the original exhaust or wait for the standard repair time.
Link pipe and catalytic converter for installation: this kit includes the specific catalytic fitting and the corresponding bracket and accessory kit, allowing installation without structural modifications. Made in Italy. 2-year international warranty. Removable db-killers and catalytic converters: the noise reducer (DB-KILLER) and catalytic converter may be removed only for RACING use on circuits. Using the open version on public roads does not comply with the regulations governing road traffic.
The kit can be used for the annual official inspection. The specific homologation certificate and assembly instructions are provided; each silencer bears its homologation code. If any problems arise during installation, stop and suspend the work, then immediately request information and/or advice from customer care by emailing [email protected].
