Skidad,,
I've had several different pipes and silencers on my 03 and 97. The stock euro from my 97 was by far the quietest one. well,, I take that back.. I pieced together a ktm silencer from a 250 to fit once on my 03 and it was very quiet.. but I never got the mounting to work. I ended up giving that to a buddy who needed one for his ktm.. I would like to have finished that but never did. Still have the 97.. but I also have the stock hockeystick and a sparky to try to fit on..
