ARROW Exhaust - Aprilia RS4 125

ARROW Exhausts have produced a replacement upgrade exhaust system for the Aprilia RS4 125.

The Aprilia RS125 ARROW Exhaust was the leading choice for a replacement and upgrade over the standard fitment. And that looks set to continue following Aprilia's release of the four stroke RS4 125 which supersedes the two stroke RS125.

Hand made in Italy, the system has the same high build quality and finish you'd expect from one of the worldís leading exhaust manufacturers. It is fully road legal/approved and has European homologation...

The ARROW RS4 125 exhaust is made with stainless steel pipe work which joins to the road approved anodised aluminium silencer.

The silencer outlet is again in stainless steel exiting the bodywork giving it a MotoGP styling and also features an easily removable baffle which gives two options for the sound from the exhaust which is deeper and throaty compared to the standard system.

The exhaust provides a decent increase in power throughout the rev range and especially at the top end (see dyno graph - below).

....The weight of the system is also reduced as it also removes the heavy standard Cat; there is also an ARROW Catalytic Convertor Kit available as an optional extra. This just slides onto the exhaust and can be easily fitted and removed.

Even fitted its still offers a notable weight saving.

So it looks better, increases power, sounds better, and weighs less!
