I just installed a Dr. D slip on on mine today. I dont have the quiet core, but its the first time I ever had the cops called on me in my neiborhood. Its that loud. It dont seem loud while your on it, But I had my son rip it down the street and its louder then my buddy Harley...by far. ..very distenct sound, I dont think I have ever heard a exhaust that sounds anything like it. I do like the sound very much though I havent had any ride time on it yet. I will let you know after this weekend. B)Originally posted by dndj@Aug 26 2004, 09:34 PM
Hey Desert - I'm seriously interested in the Dr. D slipon. Do you know where I can get some additional specs and info, especially on the quiet core insert/spark arrestor. Have you had a chance to do any testing with the core in?
94dB is very impressive, I'm looking for a quiet pipe since the Oregon Dunes NRA limit is 93dB. I have heard the stock exhaust HRC end cap is around 96dB.
