I currently have Toda dual exhaust with dolphin tips on my Ap1. I'm thinking about switching it out with a single tip of some sort. I want something a bit louder and more "raw" sounding. Some weight savings and HP gains would be great too. I don't want it to be crazy loud and too drony.

Does anybody know how the sound level in my exhaust is compared to single tip exhausts?
