Stock Pipe Loudness?

[†2005 400ex†]

Does anybody know how many dbs a stock 400ex muffler is rated? I just want to get an idea of how it rates to an aftermarket pipe. Thanks

stock pipe is right at 88 dbs. an open after market is aroudn 104 and a after market muffler that has a quiet core is aroudn 96-98 dbs
