moestock: I'm stile breaking it in, but so far it has really steady acceleration. No so-called "burbles", but that's with smooth acceleration.
*thoughts: in my opinion, sports grille really improves looks of Impreza. It's painted in body color so headlights are separated from the grill. Personally I dislike continuous appearance of the standard impreza front(left light->gray grille->right light). I like headlights to be accented and grille as simple as possible(here goes sports grille).
