Description
Arrow has been supplying high quality exhausts for over 20 years. Neatly finished, lighter than the original exhausts, but also more beautiful and better sound.
Yamaha MT-07 2021-2024 with type number RM33 Arrow exhaust system.
Thunder aluminium dark silencer with carbon end cap 71930AKN.
This exhaust has an EU approval and removable dB killer.
The approval is engraved on the silencer and comes with a certificate.
There is a choice of two stainless steel collector systems with and without catalytic converter.
The collector system without catalytic converter 71758MI is not approved
And the collector system with sports catalytic converter 71758KZ is approved.
With the approved collectors, the approval is also engraved in the collectors and a certificate is included.
The sports catalytic converter is removable.
Because of the collectors without a catalytic converter, the engine will make a lot more noise and get more power.
This is also the case with the collectors with the sports catalytic converter, only this is slightly less than with the collectors without a catalytic converter.
The muffler comes with the new Arrow logo as shown in the first picture, Black with a yellow A.
If you have any questions, please don’t hesitate to contact us.
