The Indy-Race silencers have been designed for use on certain motorcycles, primarily those that require an under-seat silencer (which makes it difficult to use existing Arrow exhausts), but once available, the Indy-Race silencers have also been used in some "standard" systems.
The design was inspired by the shape of certain American circuits (hence the name of the range); the section allows for reduced dimensions while maintaining a good internal volume to dampen noise with very good output power. The internal parts are made of stainless steel, welded using TIG/MIG.
This silencer does not remove the original catalyst.
