Dramatically improve mid/high end power by replacing the catalytic converters with a free-flowing x-pipe while adding aggressive sports car sound and throttle response; recommended for track and off-road use only.

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.

FEATURES:
• Fits all 997 Carrera vehicles from 2005-2008
• Adds 12 horsepower and 12 ft-lbs of torque for improved throttle response
• Recomended for track and off-road use only
• Designed for maximum power and throttle response
• Adds an aggressive exhaust tone
• Saves 10lbs from the rear of the vehicle
• Used by many Rolex Grand Am race teams as well as PCA/POC and HPDE drivers

Why We Choose HJS Catalytic Converters: 
HJS German imported catalytic converters are made from some of the highest grade materials you can find in a catalytic converter. This yields high performance gains and longevity so it wont deteriorate over time like lower grade catalytic converters. These catalytic converters flow up to 93-95% of a straight pipe in most applications. The benefit is that you get the "straight pipe sound" while still being able to provide enough emissions scrubbing to prevent a check engine light.

Sport Catalytic Converter (STREET) - This product removes the OEM catalytic converters from the vehicle, and as such, is strictly intended for closed track events and off-road use only. This product contains a High-Flow Sport Catalytic Converter solely intended for track and race cars as it is NOT California Air Resources Board Certified and not EPA certified. You are hereby informed and warned to check your local, state, and federals laws before buying and installing these or any aftermarket parts to be sure whether usage is in violation. All installation-risk and use-risk is borne by the end-user and installer of these parts.
