Porsche 996 GT3 Catbypass X-pipe

Replaces the heavy and restrictive catalytic converters with a lightweight free-flowing performance x-pipe for maximum power and sound                                                        

NOTE: The Catbypass X-Pipe provides dramatic power increases in the mid to high end of the RPM range.  Street drivers may notice a small torque loss at low RPM's, which is why we recommend the Sportcat X-Pipe for street applications.  Please also bear in mind that this system does not include catalytic converters, so the Check Engine will most likely be triggered.  This is not an indication of any actual issue with the engine, and does not prevent normal vehicle operation.  Optional O2 Spacers are also available to help keep the CEL from being triggered.
