i ordered the new "stage 2" silencer from m4 last week. got it in the mail today. according to m4 it drops the db. down 4 points. i installed it today and just did some revving in the driveway and it is WAY more quiet than with the provided silencer. very nicely produced piece also. here are some pics of the new silencer. i will repost after i go for a ride to see if its sounds better or worse under a load and normal riding conditions. but so far, its a big difference in the noise level.
