Porsche 911 996 Carrera X-Pipe 200CPSI Exhaust Catalytic Converters 105043

These 200CPSI catalytic converters are direct fit and are an effective stainless steel performance part. These are an X-Pipe design optimised for sound and power, with power gains of +12 to +15BHP as well as producing a higher-pitched racing sound compared to straight (cross-over) cats. They do not require any ECU remapping and original lambda sensors can be used from OE parts, however performance re maps are available at a discount price when purchasing the product- contact us for details. It is recommended to re map the ECU for significant performance gains to fully utilise the power of the cats and engine, but the part will fit perfectly and enhance the vehicle's performance without such a map. The pipe diameter is 54MM, same as OE.
