I wouldn’t bolt on a front pipe and downpipe without getting a tune regardless, do not sure why that tid bit is in there, with a tune you’ll make more power with the Prl pipes vs the afe. The whole point of bolt ons is to get a tune afterwards so the car running at its maximum efficiency. If not your afr’s will be all wacked out, then damage your motor like others already have.
