Ok, So I have a 2005 yz125 with a pro circuit platinum expansion chamber and a 304 shorty pipe. This bike is incredibly loud. The noise doesn't bother me, I actually love it. However, the people around me do not appreciate it much. I am looking for the quietest exhaust with out loosing performance. The pro circuit isn't bad when your not on the pipe, but its 125, so I'm always on the pipe. any recommendations would be greatly appreciated. Thanks in advance.
