Are db killers removable? Altering the db killer welds or anti-tamper screws or removing the fixture is illegal for road use and non-compliant with EU directives; this is only possible for RACING use on circuits. The use of the open version on the road does not comply with public road traffic regulations.
WARNING: this item is approved for noise, the customer must verify in advance if the presence of the original catalyst or GPR catalyst is required in their country to comply with road traffic regulations and to carry out the annual inspection.
You can use the kit for the official annual inspection.
Installation recommendations: GPR products are plug and play, but it is still recommended to install the products in a professional workshop; no claims will be accepted for incorrect installations.
The specific homologation certificate is provided, along with installation instructions; each silencer bears the homologation code. In case of problems encountered during installation, it is mandatory to stop and suspend the activity, and to immediately request information and/or advice from customer service.
Is it limited to 95Db for Tyrol and Switzerland? No, but this limit is required only for local citizens and not for tourists.
No structural modification of the bike is required for installation to use the product in an approved version. It is recommended to read the instructions in the package or the tutorials available on YouTube.
The exhaust has a removable db killer (noise limiter) for racing use; removing the db killer is not ONLY illegal, but the customer assumes responsibility for using the bike as on the track only, without bags, without flashlight and number plate holder or any other parts that could conflict with the different gas angle due to the transformation into a racing version. Abuse of this situation on the road will result in the loss of product warranty. This starts from the purchase, with the 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 accept to reinstall the original exhaust or wait the standard time for the repair.
