Arrow Exhaust Systems.

Race silencers are stamped ‘Not for Road Use’.
Silencers described as ‘with baffle’ are homologated for road use, but have a removable sound absorption device for track use.

Four stroke pipework is lightweight stainless steel (except where described as ‘all titanium’), two stroke pipes are lacquered mild steel.

High Level – in most cases means that the pillion footrests must be removed.

Motocross silencers which are marked ‘db killer available’ can be fitted with the optional baffle which further reduces noise. This item can be bought in the accessories section.
