Upgrade your Volkswagen MK8 GTI with the CTS Turbo EVO4 Race Downpipe. This downpipe was engineered to improve exhaust flow, reduce backpressure, and unlock additional horsepower and torque.
The factory downpipe is highly restrictive and limits performance, especially on tuned vehicles. This high-flow race downpipe allows exhaust gases to flow more efficiently, improving turbo response and overall engine performance.
Quick Fitment Overview
- Compatible with Volkswagen MK8/MK8.5 GTI
- Race catless downpipe for maximum performance
- Improves exhaust flow, turbo response, and power
- Direct-fit installation using factory mounting locations
Product Description
The CTS Turbo EVO4 Race Downpipe is constructed from high-quality stainless steel and features a 3.5" cast downpipe flange paired with mandrel-bent 3" tubing for optimal exhaust flow.
This design reduces backpressure and turbo lag, allowing your engine to breathe more efficiently and produce increased horsepower and torque especially when paired with ECU tuning.
The downpipe is precision engineered with factory mounting locations for proper fitment and includes a removable reducer to integrate with the factory exhaust system or aftermarket catback setups.
Expect a more aggressive exhaust tone with improved performance while maintaining minimal drone when paired with the factory exhaust system.

Vehicle Compatibility
- Volkswagen MK8/MK8.5 GTI (2022+)
Note: Not compatible with OPF/GPF-equipped vehicles. This is a race-only product intended for off-road or competition use.
Most 2022 and newer vehicles are equipped with updated “tamper-proof” downpipe hangers, which can make removing the factory rubber hanger more difficult. To simplify installation, we recommend sourcing an earlier-style hanger (Part Number: 1K0253144AE) from your preferred OEM parts supplier.
Installing this product may trigger a Check Engine Light (CEL). Proper engine tuning software is required to address this. Always confirm compatibility and requirements with your tuner prior to installation.
