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 catalytic converter is an emissions control device to stop harmful exhaust gasses from entering the atmosphere. In 1993, they became legality in the UK as part of the Euro Emissions standards. The aim of them is to improve air quality. As emissions standards have become more stringent the number of cats on a vehicle has increased. Many vehicles now have two or more to enable them to meet the Euro Emissions standards.
Our cat is made up of the following components:
• Ceramic monolith of a honeycomb design to allow free air flow and maximum surface area, coated with precious metals to enable the conversion of gasses that pass through it
• Interam matting to hold the monolith in place. The matting expands when exposed to heat to supply the pressure needed to keep the monolith secure
• A grade 409 stainless steel can (or housing) to provide protection and enable the cat to be built into the exhaust system. 409 grade can contain upto 90% iron and will be prone to rust. It still has higher rust-resistant properties than mild steel.
