Brian:
Thanks for the heads up on the billet ends, didn't know they were available. You can run the pipes without rejetting but the bike will run far stronger and better with a rejet. I would remove the AI before you ride another mile and ruin those nice chrome header pipes. They'll turn blue & brown in a heart-beat which will require lots of work to get close to a new looking state. (see my photos when I bought the bike) It's a simple 30 minute job. Run the bike low on gas so the tank is easy to manuever off/on. Give this site a shout if you have questions or run into any difficulty.
You won't be disappointed in the pipes, I love my SS sound and looks.
