The Arrow Thunder for Aprilia RS 124 in Euro4 standard replaces the original underfloor rear silencer like the previous Euro3 silencer. Basically, Arrow also places the rear silencer under the engine, but adds an additional stainless steel pipe which ends just below the swingarm for a more sporty look. The rear silencer itself is made of simple aluminium, as relatively little of it is visible. The visible pipes are made of stainless steel and therefore rust-free with good care .
The version offered here is an all-inclusive solution including all pipes and necessary mounting materials as well as a catalytic converter for Euro4 compliant and legal mounting. If the catalytic converter is removed, or the dB-killer is taken out of the rear silencer, it goes out. Otherwise no problems are to be expected with the Tüv or other controls.
