    if you want to run open downpipe, make sure you have at least 18-24" of pipe after the o2 bung so it doesn't get contaminated afr readings.

    some stock ones put the o2 right @ the turbo, but the pressure can damage the o2 and give slightly erroneous readings. i suggest anywhere 12" after the turbo at the closest. the more common is towards the end of the downpipe underneath the axle area, but if you do that you'll need a bolt on extension if you want to run open dp.

    you can just do a bolt on extension for the tuning and remove it if you want to stay open dp. we've had to do that on some cars that come in, but we don't always have the perfect extension on hand without having to make/modify one.
