Porsche 911 991 Carrera Valved Rear X-Pipe 105025

These are a unique X-Pipe design optimised for sound and power, with power gains of +12 to +15BHP. They do not require any ECU remapping and original lambda sensors can be used from OE part, 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 engine, but the part will fit perfectly and enhance the vehicle's performance without such a map. The X-Pipe design produces a higher pitched racing sound than straight catalytic converters which are not linked.
