HKS made the Racing Muffler Exhaust system for all out race Toyota Supras. Designed to be up to 40% lighter than the Hi-Power systems for the same car. The piping is 304 stainless steel with up to a 102mm diameter, depending on application. The titanium muffler versions feature a real titanium 170mm canister design with a slip fit design so it will match any body kit or spoiler depth.
These system are very loud but most applications do feature a removable silencer.
