The Spec D is a good exhaust. Very loud though. It idles around 89-90db, 3k around 95-97db, and at red passes the 120 mark. I had one until it was stolen. You will feel a bit of a loss at the bottom end, but it will start to pick up around 2k. If you are expecting to have a conversation with your passengers, you'll learn to yell over the sound. The sound though is deep and very aggressive.
