Is the intake still quiet and don’t hear the high pitched turbo noise coming through?
How about the seat of the pants feel? Feel much of a difference? Does it feel less torquey down low in city driving?
Sound has changed, it's a good change. A bit deeper, a small turbo sound when you shift, but nothing that's anywhere near obnoxious or annoying. To really hear it, you gotta come onto it. Power difference is negligible, but it is definitely more responsive.
