Ideally quite easy to fit...? hi, i'm a little confused....my bike (honda cbr rr 2003 600cc) is pretty quiet and i'd like a bit more noise behind me...vanity and so cars hear me coming. I've been looking at loads of exhausts and they're super expensive. i dont want anything too flash, just something easy to have fiteed...i have heard that akrapovic are good? also, is this known as a "silencer"? seems odd to me! any tips would be great, thanks
