No structural modifications to the bike are required for installation in order to use the product in an approved version. It is recommended to read the instructions in the package or the tutorials available on YouTube.
For online purchases, it is necessary to activate the warranty by sending the appropriate stamped coupon from the installation workshop via email to certificato@GPR.it; for physical purchases, the shop stamp is sufficient. The exhaust features a removable db killer (noise limiter) for racing use; removing the db killer is not ONLY illegal, but the customer assumes the responsibility for using the motorcycle solely on the track, without luggage, flashlight, number plate holder, or any other parts that would interfere with the different gas angle resulting from the conversion to racing version. Misusing this situation on the road will result in the loss of the product warranty. From the date of purchase, there is a right to repair with return to the GPR factory or the nearest official distributor at the customer's expense.
GPR cannot provide a new silencer in place of the one to be repaired; the customer must agree to reinstall the original exhaust or wait for the standard repair time.
The new Grand Prix Evo Titanium silencer from GPR was created to celebrate its 20 years in the MotoGP/Moto2/Moto3 World Championship. The first Grand Prix line was presented in 2005, during the debut of the Konica Minolta team and rider Makoto Tamada, as well as the LCR team and rider Casey Stoner. The silencer is conical, with a special shape ranging from a diameter of 90 mm to 130 mm in circumference and a variable length depending on the bike. It is equipped with a natural colour titanium sleeve, a CNC machined black end cap with a pentagonal outlet, and a silencer.
