Important Fitment Notice

Please send us your VIN or chassis number before ordering so we can help check fitment. If these downpipes are catless, they are intended for off-road and motorsport use only. Removing catalytic converters from a road vehicle in New Zealand may breach emissions rules and cause a WoF failure; the owner is responsible for compliance.
