CTS Turbo EVO4 FWD High-Flow CAT MK8 VW GTI/8Y Audi A3

The CTS Turbo EVO4 FWD High-Flow CAT is purpose-built for MK8 Volkswagen GTI and 8Y Audi A3 front-wheel-drive applications. This catalytic converter reduces exhaust restriction inherent in factory components, allowing freer flow from the turbocharger while meeting emissions standards. Constructed for durability under increased thermal loads, it suits tuned EA888 evo4 engines where optimised exhaust flow is essential. Direct fitment design integrates seamlessly with stock or modified exhaust systems, making it ideal for workshops upgrading client vehicles seeking responsiveness and efficiency gains without sacrificing regulatory compliance.
