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 Light (CEL) will most likely be triggered. This is not an indication of any actual issue with the engine, and does not prevent normal vehicle operation.
DISCLAIMER: 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, never to be driven on public roads. This product is or contains a Racing Cat Bypass Pipe, which will give you check engine lights on OBD2 cars. We suggest pairing this product with racing software to prevent fault codes and check engine lights. Racing Cat Bypass Pipes are solely intended for track and race cars as they are NOT California Air Resources Board Certified and not EPA certified.

Fitment is perfect, bolts right up and proper placement for O2 sensors. Sound is not too noticable while idling however once about 3k RPM sounds beautiful. Throttle respone is improved as well. Expert craftsmanship and great customer support too. Couldn't be happier.
This x-pipe is awesome. Much more power and great sound. Keeping up with the GT3s on the track.
Thank you very much! Your exhaust made my Porsche sound like a proper Porsche flat 6 should sound. Also I did the install myself in my garage and the fitment is great, and the hardware you supplied was top notch. Thanks again.
Thanks a lot for the quick shipping. I placed the order and everything showed up at my door in less than 24 hours!(Btw I really appreciate that you guys ship via international priority and also marked the value as $40) Amazing! I installed the cat bypass for the 996 last night and it sounds great. Fitment was pretty close to spot on as well. I will definitely order from you guys again and will recommend you to all my friends.
