Indy-Race mufflers were designed for use on certain motorcycles, mainly those requiring an under-seat muffler (making it difficult to use existing Arrow pots), but once available, Indy-Race mufflers were also used in some "standard" systems.
The design was inspired by the shape of certain American circuits (hence the name of the range); the cross-section reduces dimensions, while maintaining a good internal volume to dampen noise with very good power output. Internal parts are stainless steel, TIG/MIG welded, and the silencer body is available in titanium, carbon fiber and aluminum with steel or carbon end caps.
Indy-Race mufflers are available in a road-approved version with removable baffle.
