CTS Turbo EVO4 FWD Race Downpipe – MK8 Volkswagen GTI / 8Y Audi A3 | 3" Stainless Steel

Free up the power your MK8 GTI or 8Y Audi A3 is being held back from with the CTS Turbo EVO4 FWD Race Downpipe — a 3.5" cast flange / 3" mandrel-bent stainless steel race downpipe engineered specifically for the EVO4 FWD platform with Garrett turbocharger. The factory downpipe is a significant restriction in the exhaust system, with adverse effects on horsepower that become even more pronounced once the car is tuned. The CTS Turbo downpipe eliminates that restriction, allowing exhaust gases to flow freely and unlocking the additional power your build demands — all with great sound and no drone even with the factory exhaust.

⚠️ Race-Only / Not Street Legal: This is a race-only downpipe — it removes the catalytic converter and is not legal for street use in emissions-controlled jurisdictions. For off-road and track use only.

⚠️ Not Compatible with OPF/GPF Equipped Vehicles: This downpipe is NOT compatible with OPF (Otto Particle Filter) or GPF (Gasoline Particle Filter) equipped vehicles. Verify your specific vehicle's emissions equipment before ordering.

Key Features

• 3.5" Cast Stainless Steel Downpipe Flange: Large 3.5" cast stainless steel downpipe flange for maximum flow at the turbo outlet — eliminates the factory restriction at the most critical point in the exhaust system

• Removable Reducer – Fits Factory Exhaust: Includes a removable reducer to connect to the factory exhaust — no need to replace the cat-back exhaust to run this downpipe
• Factory Mounting Locations: Uses factory mounting locations and includes stainless steel clamps — direct-fit installation with no fabrication required
• Great Sound, No Drone: Delivers a great exhaust note even with the factory cat-back exhaust — no drone
• EVO4 FWD / Garrett Turbo Specific: Designed specifically for the MK8 EVO4 front-wheel-drive platform with Garrett turbocharger — not compatible with AWD (4Motion) variants
