Updated: 21 November 2014

This is the new street legal slip-on for the hugely impressive Aprilia RSV4 from Italian firm Gianelli.

It has a diamond-shaped silencer and a mid-pipe in stainless steel.

Everything is secured to the tail section using a black anodized aluminium support bracket.

Silencers are available in titanium, carbon fibre, titanium and aluminium and, as an option, a street legal catalytic converter is available.

Silencers in titanium and carbon fibre are available also with a carbon endcap.

Starting from the 154hp measured on the wheel using OE silencers, we reached a peak power of about 158hp with Giannelli silencers.

Power increase becomes noticeable starting from low RPM according the Gianelli.
