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

Free up your MK8 VW GTI or 8Y Audi A3 with the CTS Turbo 3.5" high-flow cat, built for the front-wheel-drive EVO4 platform. The factory downpipe chokes flow and saps power once you tune; this one smooths the path so your exhaust gases scavenge cleanly, releasing the horsepower the OE pipe holds back — with a great look to match.

A 3.5" cast downpipe flange, mandrel-bent 3" stainless tubing and factory mounting locations make for serious flow and a straightforward install.

Fitment

• 2022+ VW MK8 GTI
• 2022+ Audi 8Y A3

Not compatible with OPF/GPF-equipped vehicles. Most 2022+ cars use updated tamper-proof downpipe hangers that make the rubber hanger hard to remove; an old-style hanger can be sourced from your preferred OEM parts retailer (part 1K0253144AE). A CEL will appear without proper tuning software — check with your tuner.
