An original GPR product, developed through extensive experience in the World Motorcycle Championship. It offers innovative design, increased performance, significant weight savings, and an improved motorcycle sound.
No structural modifications to the motorcycle are required to install the product in its approved version. Please read the instructions included in the package or view the tutorials at www.gpr.it and on YouTube.
For online purchases, activate the warranty 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, but also means the customer assumes responsibility for using the motorcycle only on circuits, without bags, turn signals, a license plate holder, or other parts that could conflict 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 covers repair at the GPR factory or the nearest official distributor, at the customer's expense.
GPR cannot provide a new silencer in place of one being repaired. The customer must agree to reinstall the original exhaust or wait for the standard repair time.
Manifold and catalyst: the kit includes the specific manifold with the catalyst mounted in it. It can be installed without cutting or modifications. Flanges, bushings, brackets, and screws are included where necessary. Made in Italy, 2-year international warranty.
Removable db-killers and catalysts: the noise reducer (DB-KILLER) and catalyst 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, and each silencer bears its homologation code. If you encounter problems during installation, you must stop and suspend the work, then immediately contact customer care by email at [email protected] to request information and/or advice.
