Stage 2 requires an aftermarket downpipe at a very minimum (a full turbo-back exhaust is recommended for maximum performance). If you are running the stock downpipe with a dump tube/cut downstream, you would run the stage 1 map (that is not a very common mod - you would be better off with a full turbo-back exhaust and stage 2 map).
