Installation and Usage

Downpipe replacement on a twin-turbo V8 is a complex job that should only be carried out by an experienced performance workshop. Test pipe style downpipes may remove or bypass emissions equipment and can trigger warning lights, so ECU calibration is typically required. Check oxygen sensor fitment, joint sealing and heat shield clearance after installation.

Important Fitment Notice

Please send us your VIN or chassis number before ordering so we can help confirm fitment. A test pipe or catless downpipe is intended for off-road and motorsport use only. Removing catalytic converters on a road vehicle in New Zealand may breach emissions rules and result in a WoF failure, and compliance is the owner's responsibility. Images are for reference only.
