DesignTek Sport 200 Cell catalytic converters 996 Sport Cats Give a gain of +12 to 15BHP.
Made from high grade stainless steel.
Only for cars with pre & after sensors. Some USA spec cars may require sensor point modification to fit.
The item can be used on vehicles equipped with only a pre sensor. The post sensor hole can simply be blanked off during installation. Since vehicles with only a pre sensor are generally less sensitive than those with dual sensors, this setup is acceptable. Blanking the unused hole is a common and effective method to ensure a proper fit for this product on pre-sensor-only vehicles.
Fits:Porsche 996 Carrera 3.4L / 3.6L
A Voucher for £100 available when you buy this product. For more information CLICK HERE
Please note: These sport cats will make your car sound louder than with stock cats. If you have, or intend to install sport silencers, you may find the car is a bit loo loud. We recommend to use one sport exhaust component if you are concerned about decibel levels.
NOTE: In the United Kingdom, sports catalytic converters and bypass pipes do not have type approval and are not legally permitted for use on vehicles manufactured after 1st March 2001. They are not MOT compliant and cannot be used on public roads. These components are intended solely for race and track use.
For vehicles manufactured before 1st March 2001, a non-type approved sports catalytic converter may be fitted, provided it offers comparable performance to the original and the vehicle continues to meet the applicable emissions standards for its age. The vehicle must still pass an MOT test.
If you are located outside the UK, please check your local laws and regulations to ensure compliance.
