CTS Turbo EVO4 AWD RACE Exhaust Downpipe MK8 VW Golf R/8Y Audi S3

Unlock the potential of your MK8 VW Golf R or 8Y Audi S3 with this CTS Turbo high-flow race downpipe. Purpose-built for the EVO4 all-wheel-drive platform running the Continental turbocharger, its generous 3.5" diameter and catless design slash backpressure and turbo lag to free up serious horsepower and torque — with an aggressive note to match.

Why it works

• Premium stainless steel construction for durability and corrosion resistance
• 3.5" diameter maximizes exhaust flow for bigger gains and reduced lag
• Cast stainless steel downpipe flange, 100% TIG welded
• Removable reducer to mate with the factory exhaust
• Factory mounting location with stainless steel clamps
• Great sound even with the factory exhaust, no drone

Not compatible with OPF/GPF-equipped vehicles. Most 2022+ cars use updated tamper-proof downpipe hangers that make removing the rubber hanger difficult — an old-style hanger (OEM part 1K0253144AE) can be sourced from your preferred OEM parts retailer. Proper tuning software is required to clear the CEL that will occur — check with your tuner. Stage 2 software is required to avoid a check engine light.
