Our Mazda RX-8 Sports Cat Downpipe replaces the standard restrictive downpipe and catalytic converter with a stainless steel, 2.75″ one-piece item. Increasing the bore of the downpipe and replacing the restrictive catalytic converter with a sports catalytic converter allows the exhaust gasses to flow much more freely, increasing the power output of the engine and improving throttle response.
It has a 200 cell sports catalytic convertor included.
