EVO4 3.5" High-Flow Catalytic Converter

The CTS Turbo EVO4 FWD High-Flow CAT is a performance downpipe engineered for the MK8 VW GTI and 8Y Audi A3. Constructed from 3.5″ stainless steel with 100% TIG-welded seams, this downpipe is designed to replace the restrictive factory unit. By allowing exhaust gases to flow more smoothly, it aims to unlock additional horsepower and improve the vehicle's sound, even with the factory exhaust system, without introducing drone. Key features include a 3.5″ cast downpipe flange, mandrel-bent 3″ stainless steel tubing, and the use of factory mounting locations for a precise fit. It also comes with a removable reducer to ensure compatibility with the factory exhaust. The product is specifically designed for the EVO4 FWD platform equipped with a Garrett turbocharger. Fitment is confirmed for 2022+ VW MK8 GTI and 2022+ Audi 8Y Audi A3 models. However, this downpipe is not compatible with OPF/GPF equipped vehicles. Additionally, it is important to note that to remove the Check Engine Light (CEL) that will likely occur, proper tuning software must be used; users should consult with their tuner. All CTS Turbo sales are final, and returns will not be accepted.
