ARROW Competition EVO Full Exhaust System
Aprilia RS 660 (2025)

Established by Giorgio Giannelli in 1985, Arrow performance uses the latest in CAD/CAM technology to produce some of the finest exhaust systems available.  With several championships in multiple genres of motorcycle racing to their name, Arrow has the experience needed to produce exhausts optimized for today's high performance engines.
 

COMPETITION EVO FULL SYSTEM

Competition exhausts are designed and developed specially for bikes and engines tuned for races, on the basis of the experience made in track races all over the World: these exhausts are a direct evolution of the ones used in SBK and SS bikes.
Competition exhausts are made with the deepest attention to details, they ensure to exploit with the best possible efficiency engines tuned for races: bigger sections, section changes finely designed and shaped, special silencers, top-quality materials.
These exhausts are welded manually (TIG process) and are available in a “full titanium” version or with collectors and manifolds in stainless steel and silencer and link pipe in titanium. In all cases a built-in sensor plug is available, to be able to check ECU settings and make necessary modifications if needed. The sections of the various silencers available give the best performance and the best compromise between performance, dimensions and noise (noise must meet race rules limits).
Style is completed with the carbon endcap and the silencer, depending on application, can be fitted with a removable baffle. Competition exhausts are the top-level exhausts in the market, for style, technology and performance.

PRO RACE SILENCER

Pro-Race silencers design comes from the first prototypes made for MotoGP. Pro-Race silencers are built putting together a conical-shaped part (the main body of the silencer) with a cylindrical ending section (ø98mm) and these are available in titanium or nichrom (a stainless steel alloy).
The silencers are secured to the bike by means of mounts welded to the main body, their cone-shaped design provides a reduction of dimensions and weight, but it also reduces the overall volume of the exhaust, thus limitating noise damping capabilities and the application on bigger or demanding engines.
Pro-Race silencers are available both in a street legal and racing version.
