Our Sports Cats are manufactured entirely from stainless steel with a low density stainless steel monolith. The Sports Cats utilise an increased amount of precious metals in order the reduce the number of cells per square inch (cpsi) from the normal 400cpsi down to 200cpsi, thus improving performance by as much as 15 Bhp.
