Are the db killers removable?

Using the open version on the road is not compliant with public road traffic regulations.
WARNING: this item is approved for noise; the customer must check in advance if the presence of the original catalyst or the GPR catalyst is required in their country to comply with traffic regulations and to carry out the annual inspection.
You can use the kit for the official annual inspection.
Mounting recommendations: GPR products are plug and play, but it is still recommended to have the products installed in a professional workshop; no claims will be accepted for incorrect installations.
The specific approval certificate is provided, along with the installation instructions; each silencer bears the approval code. In case of problems encountered during installation, it is mandatory to stop and suspend activity, and immediately seek information and/or advice from customer service.
Is it limited to 95Db for Tyrol and Switzerland? No, but this limit is only required for locals and not for tourists.
No structural modifications of the motorcycle are required for installation to use the product in an approved version. It is recommended to read the instructions in the package or the visible tutorials on YouTube.
The exhaust features a removable db killer (noise limiter) for racing use; removing the db killer is not ONLY illegal, but the customer also assumes responsibility for using the motorcycle as if on the track only, without a tail pack, without a flashlight and license plate holder, or other parts that could interfere with the gas angle due to the conversion to racing version. Misuse of this situation on the road will result in loss of product warranty, counting from the date of 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 being repaired; the customer must agree to refit the original exhaust or wait the standard time for the repair.
