Ah thanks, it's a US-spec xDrive28i so the exhaust may have a flap, although I'd hope not as it's terribly boy-racer childish to me trying to make more noise for the sake of it.
What's your definition of "tighter steering" does it change the valving and response curve, or just make it heavier. If it's the latter then it's of zero value, if it's the former then great.
