Here is some info for you, and pics of what I did to quiet-down my UFO 4/1. The last attachment is just for fun.

Note: I have a Dragstar and you need earplugs! I don't care what baffle you have, with one exception, my "Franken-bike" muffler, which may be ungainly in aesthetics but which allows me to run VBoost, Dynojet Stage 7 jet kit, and not annoy a law enforcement officer, even when he's riding to my right (the side the 4/1 can is on!)
Attachment 1: Franken-bike muffler (very quiet)
Attachment 2: Daytona, UFO Dragstar 4/1 minimum baffle (very, very LOUD)
Attachment 3: UFO Dragstar 4/1 with megaphone, slightly less-loud than above
Attachment 4: UFO logo on the megaphone, Jon Cornell shipped this megaphone to me less than a month before his death
Attachment 5: making canisters work on the 4/1 header pipe
Attachment 6: what's in the treeline?
