I wouldn't buy anything else I don't think. The fit, finish, and overall build quality is second to no-one, and it sounds sooooo sweet at revs... and if you really want the best, go full ti. Beautiful. However, there are PLENTY of fantastic aftermarket pipes on the market. I just think Akrapovic is the cream of the crop... and also the choice of every major factory Kawasaki team worldwide that it made it my choice very easy.
