Does anyone know how much faster if any the australian H-6 is than ours. I don't know how to convert their specifications. I'm just wondering because it looks as if they have a much better exhaust.

I guess my question really is if it is faster what is the difference. Is the added horsepower just from the exhaust and a differently mapped ECU. or is the car as different as the B4 to our legacy. I'm wondering because I can't find anything for my H-6 to increase it's horsepower. Do I need to import something from Australia or does anyone know where I can get a better exhaust. The H-6 has a dual stage exhaust and I don't know if putting on a regular muffler and new piping will just make the torque even worst.
