Yes you r right I had the part # s mixed
What would happen If I ran without any cat muffler on either side would there be any performance difference or engine damage
i don't think you had a cat anyway. but no, you would not damage your engine, and if you add a different exhaust, you would probably notice a slight increase. you would see a lot more if you went with the full stage 1.
fuelmoto was recommended a couple posts up. i echo that recommendation. good folks, and they won't steer you wrong.
get some slip-ons of your choice and a Fulsac true dual kit. Front head pipe stays the same and most of rear cyl stays. I had one and it worked great, easy to install.

I've got an 07 RKC. Like 'skratch' and others have said, you never had a cat. 80% of exhaust comes out the right side because of 2-1-2 exhaust system on a Harley.
