I had a q pipe on my 02 and it was good. I have the FActory4 on the 05 and it is load. The best pipe for being quiet is probably the stock. If I remember the Q-pipe was loader than the stock pipe but passed a Hollister with 95db (brand new)

It kept getting louder as I rode it untill I repacked it

How about a Pro Moto Billet end cap on a stock silencer with silent insert? I've used them on 2 different CRF's and a couple of my buddies do also,no major power loss,extremely minimal at best.At low RPM noticeably quieter than stock or other so called quiet inserts that I have tried,at high R's still pretty loud but still much quieter than stock and the sound does not carry as far all in all I find PMB w/silent insert to be worthy even for Motocross.For me this is high praise.cheers
