I have it for just under a year now and it sounds so much better than anyother exhaust out for the FZ8, atleast to me it does. It doesnt look as snazzy but its simple, sounds awesome and cheap. Its not obnoxiously loud, but it isnt quiet either.
Blueing titanium takes a lot of heat, FZ8 isnt going to put that much heat out the muffler, especially with the cat in the pipe. Some small parts of it may turn blue if the heat is concentrated.
