Audi TTS MK3 Non GPF models - Stainless Steel Cast Downpipe with Race Cat (For OE Cat-Back) - OE Cat-Back

Our range of Cast Downpipes offer further enhancements to gas-flow and heat management, being designed to increase efficiency and performance gains. Standard OEM catalysts are usually round 500-600 cells, our race catalyst reduces this to 200 cells. This makes the catalyst freer-flowing, improving gas-flow and performance.

With 200 Cell Race Cat.
