I just heard from a guy who was in Ocotillo Wells this past weekend that BLM was sound testing bikes like mad. Supposedly the ranger told him to load up his bike (Big Gun exhaust) right now or it would be confiscated since it would not have passed a sound test if he checked it. Supposedly they know which brands will pass and which won't. Dr.D w/ a quiet core is a safe bet according to the Ranger. Wow! JUST A WARNING!!! For everyone going to the dez on Halloween, order your quiet pipes now!!!!!
