CTS Turbo EVO4 AWD High-Flow CAT MK8 VW Golf R/8Y Audi S3

Tap the hidden power in your MK8 VW Golf R or 8Y Audi S3 with the CTS Turbo high-flow catted downpipe, purpose-built for the EVO4 all-wheel-drive platform. The generous 3.5-inch diameter and high-flow sport cat cut backpressure and turbo lag, so boost builds quicker and power and torque climb across the range.

Stainless construction stands up to hard driving while delivering an aggressive note, and the design keeps fitment factory-simple.

Fitment

• 2022-present VW MK8 Golf R
• 2022-present Audi 8Y S3

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.
