Exhaust systems listed as “homologated” meet the requirements fixed by in-force standards, for gases emissions and/or noise levels. Approval of an aftermarket exhaust system is valid only if the exhaust is installed on the vehicles for which the exhaust has been approved and approval is not valid if the system is used on different vehicles. With the exhaust system a summary of the information related to the approval is given, including the list of vehicles for which the exhaust is approved. It is not possible to transform a racing exhaust in an homologated one.

Vehicle type is also written in vehicle registration papers: to check if an exhaust system is approved for your motorbike / scooter it is enough to check the information given in vehicle registration documents against those given in their catalogue / website.

Arrow exhausts systems (except Competition and MX Competition systems) are designed, made and tested on a fully standard bike, checking performance and correct functioning. When installing an Arrow slip-on system not removing OE catalytic converter system, it is not needed to modify carburation settings. When installing an Arrow exhaust system (either silencer or collectors kit) requiring the removal of OE catalytic converter system, they recommend, once the exhaust has been installed, to check carburation parameters and if needed to adjust carburation settings. Competition and MX Competition systems are designed and developed for vehicles tuned for track use. The minimum level of tuning is the intervention on bikes electronics.

If installing an Arrow exhaust system requires to remove OE exhaust valve, you will find all information on the procedure in the fitting instructions. Depending on the exhaust system, in the fitting kit you will find a mechanical exhaust blanking system, to be used as specified in the fitting instructions. In other cases, they suggest to install an electronic valve blanking kit, available in the market. If removing the valve is needed to install an approved Arrow silencer, removing the valve will have no influence on Arrow silencer approval.
