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
