I heard you can get away with just the stock downpipe meaning if you gut or get an aftermarket uppipe you will be fine. or if you want, you can go stage 2 with everything catless and when it comes times to get emissions get your stock downpipe installed before. its a lot easier than the uppipe which is good.
