I was wondering what pipes are quiet! around 102 decebels. I run a bills at the moment (what my sponsors give me) and its 110. they are starting to inforce a sound rule here in western oz for 102 sooo i need to buy a new pipe! thanks!

they are also starting to enforce the sound rule here in MN too. but it is 98 dbs. kinda sucks. But I run a LRD pro 4 with a quiet core and it tested at 94db and with the quiet core out it tested at 108db.

i think most pipes come with some kind of silencer/quiet core insert. i know with my rossier i can adjust it down to 96 dbs with the supertrapp end cap. most of the quiet inserts claim to give you more top end too...
