I am so sorry Frogman, I am new to VFRworld and I have been busy packing my life so I can move to Arizona for graduate school. The Arrow pipes are very light but the sound is sort of muted compare to staintunes and others...But many of my non VFR rider friends thinks that it looks better than many other with the exception of the Two Brothers but Two Bros has one dummy pipes. I am sure by now you have already installed the pipes so you know how it looks on the bike...I like the looks alot. Enjoy!
