Js Racing Circuit Converter (CAT killer) Honda S2000 00-09

J;s Racing Circuit Converter (Cat Killer) replaces the OEM catalytic converter to free up horsepower. Generally the catalytic converter (along with the rear mufflers) are the most restrictive part on any exhaust. By replacing this part you can free up valuable horsepower which is normally strangled by these restrictive items (which in turn does not allow the exhaust to scavange effectively, leaving spent gases in the combustion chamber, reducing peak power). The J;s Racing Circuit Converter pipe offers two further benefits (as well as bolting straight in) - they come pre drilled for sensors and they have mounts for the heat shield plates that OEM catalytic converters have. Therefore the installation can look seamless, and you should experience no CEL lights as associated with cheaper alternatives.
