Installation and Notes
- Professional installation recommended
- Stage 2 ECU tuning required to prevent check engine light
- Some vehicles may have tamper-proof downpipe hangers that require replacement
- Inspect exhaust connections and ensure proper sealing during installation
Note: Not compatible with OPF/GPF-equipped vehicles.
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.
