3" High-Flow Downpipe w/ 200-Cell Cat

The CTS Turbo 3" Downpipe is engineered to replace the restrictive factory downpipe on compatible VW and Jetta models, aiming to enhance exhaust gas flow and unlock additional horsepower, especially when the vehicle is modified with ECU tuning. Constructed from T304 seamless stainless steel with 100% TIG welded seams and T304 stainless steel flanges, this downpipe incorporates a 200-cell metallic race catalytic converter to balance performance with emissions control. Its modular design simplifies installation, and it is compatible with both factory and aftermarket exhaust systems. This downpipe is designed for specific EA211 engines. Fitment includes the 2015-2021 VW Jetta SE 1.4T TSI, 2016-2021 VW Golf 1.4T TSI (MQB), and 2022-2024 VW Jetta 1.5T TSI. It is crucial to note that this part is NOT COMPATIBLE WITH TWIN-CHARGED or HYBRID ENGINES. To avoid a check engine light, Stage 2 software is required after installation. The product also carries a California Proposition 65 warning regarding cancer and reproductive harm. Installation may involve minor modifications, as noted by one user who had to cut approximately 3 inches off a section of the pipe for optimal fitment and O2 sensor placement.
