I don't have an intake yet but no regrets with my Active Autowerke catted downpipe, I really love it. Like chenry said, it's more aggressive, deeper, and louder but not overly loud at all. IMO it is sometimes hard to tell the difference in Comfort mode. Sport + is a different story, you can definitely tell something isn't stock.
