I have a carbon fiber shorty race series akrapovic slip on. It came of a 04/05 ZX10. I should fit many other models. It comes with three springs, and the connector. It connects to the stock exhaust system right before the butterfly valve. It can also be used with a full exhaust system.

$150 shipped.
