the S209 still has the standard restrictive STI downpipe with 2 catalytic converters, so even though they installed a larger turbo, that turbo and upgraded fueling system and air intake system have to push through a bottle neck that restricted even the standard stock turbo on the base STI's. Put a 3" downpipe on there with a single high flow cat (as they should have done when they built it,and retune it and it will sound much better and put out a LOT more horsepower).
