Installation and Usage

Installing both a downpipe and catback is a substantial job and should be carried out by a professional performance workshop. Whether the downpipe retains a catalytic converter has not been confirmed; if it does not, ECU calibration will be required. The remote valve system must be wired and tested correctly. Check all joints, sensors and clearances after installation.

Important Fitment Notice

Please send us your VIN or chassis number before ordering so we can help check fitment. Exhaust modifications must meet New Zealand noise and WoF requirements. If the downpipe is catless, it is for off-road and motorsport use only, as removing emissions equipment may cause a WoF failure. Compliance is the owner's responsibility.
