To install, no structural modifications are required. GPR recommends reading the included instructions or tutorial on http://www.gpr.it or the GPR channel on Youtube.


For on-line purchases, activate the warranty by sending the installation receipt from the mechanic / shop via email to certificato@gpr.it, or sending the sales receipt from the physical or online store.


The exhaust has a removable db killer (noise restrictor) for racing use. Removing the DB Killer is ILLEGAL and the customer assumes the responsibility if they use the motorbike as on the circuits only, without bags, without flash lights, number plate holder or other parts that would conflict with the different angle of the gas following the transformation into the racing version. Abuse of this situation on the road will result in the loss of the product warranty and any refund request will be rejected.


The warranty is two years from the purchase, with right of reparation with a return 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 accept to remount the original exhaust or wait the standard time for the repair.


GPR supplies a 304 stainless steel manifold including and homologated Removable catalytic converter. The package includes flanges, bushings, brackets. It mounts directly on the cylinders without any structural changes.

This is an original GPR product, developed after GPR's experience in the World Championship. It offers an innovative design, improved performance, weight savings and a full-bodied sound.

Made in Italy with a 2-year international warranty.

Tampering with the DB Killer and Removable catalytic converter welding or antitampering screws or fastener is illegal for road use within the EU directives. It is permitted only for RACING use in the circuits. The use of the open version (without the DB Killer) on roads does not comply with regulations governing circulation on the public road network.

This kit may be used in the case of annual official inspections.

GPR products are plug-and-play. However, GPR recommends the installation from a licensed mechanic as GPR will not accept any claims from a do-it-yourself installation.

If you buy online from a seller that is NOT GPR, we recommend you buy from a seller in YOUR COUNTRY to ensure that the item arrives with the correct approvals that must also comply with local legislation. Make sure before purchasing that the seller is trustworthy and offers the items that comply your road network.

Each package includes the homologation certificate, assembly instructions, and a homologation code on each silencer.

In case of a problem during installation, please stop the installation process and immediately contact customer care via email at claim@gpr.it
