hi, yours was the long sleeve.I had a micron on my 04. Don't know why mine was so huge but. Sounded slightly better than stock but for my personal preference wasn't loud enough. I'm sure it will be an improvement over the H2s stock Kawsaki muffler though if that's the version you have.
And depending where you live they might be a bit aggressive when pulling you over, noticed they're like that to riders at times, some think you might take offGuess loud is relative. It's still a large, sound restrictive slip on. Are you putting the micron in place of the stock muffler because any slip on the H2 while keeping the cat wont make a loud exhaust. It will look better than the huge stock muffler though, sound slightly better I bet. I understand in some parts of the world the sound police are in full force. Looking forward to seeing it on your bike. Good luck.
