Just bought a 2002 Ninja 12 r. It has a Yoshimura on it now but I wanted that loud intimidating sound. What slip on can I buy to replace the Yoshimura?

Hey Mate, well all slip-ons will sound the same. Factory headers are very restrictive in this bike. Last headers section in finished with small internal muffler ended with cat converter.
When I bought bike from previous owner, bike has gutted cat and no wool in muffler however it was still very quite and pass noise test with out an issue.
