3-Inch T304 Stainless Steel Cat-Back Exhaust System

The CTS Turbo MQB FWD Exhaust Downpipe is a performance-oriented upgrade for front-wheel drive MQB vehicles, including the MK7/MK7.5 Golf, GTI, GLI, and A3 FWD models. Constructed from premium materials, this downpipe utilizes T304 seamless stainless steel tubing with a 3-inch diameter. It features T304 stainless steel flanges and O2 bung, and is 100% TIG-welded and back purged for maximum durability and optimal exhaust gas flow. The modular design simplifies installation, and smooth transitions ensure efficient exhaust gas expulsion. The product also boasts a great sound with no drone, even when paired with the factory exhaust system. This downpipe is specifically designed for the following applications: 2015-2020 VW Golf 1.8TSI FWD, 2015-2021 VW GTI 2.0TSI (including Performance Pack and facelift models), 2015-2020 Audi A3 1.8TSI FWD (excluding Quattro models), and 2019+ VW GLI. To prevent a Check Engine Light (CEL) from appearing due to the high-flow catalytic converter, proper tuning software is required. Stage 2 software is recommended to avoid CEL issues. An optional CEL eliminator/O2 sensor spacer is available, though its effectiveness in preventing a CEL is not guaranteed.
