quiet exhaust

My dad just bought a 2002 yamaha ttr250 diertbike, which is a 250 4-stroke engine. It has a Pro-circuit t-4 tuneable exhuast on it, which came with the bike already installed. It sounds really good, but we took it to the mounds the other day, and it is at 101 decibles, and the limit was 94 decibles. What can we do to decrease the amount of noise it puts out? Is there a way to tune the muffler to make it quieter? baffling maybe? We have also considered just making a pipe and old muffler for it just for when we go to the mounds. Any help would be greatly appreciated.
