You're going to get 50% saying it's fine, 50% chastising you for not using a tuner....
I ran a Rinehart slip on on my stock 2010 2:1 exhaust before I did a full Stage 1. It ran fine, sounded better than stock, but still had a "muffled" sound. The CAT make a bit of heat which lead to the can blueing within 3,000 miles. I personally attribute the heat the CAT must make in order to work as the cause, not a tune issue. Yes, It could have been tuned richer, but the CAT would still put out a ton of heat.

It is running lean for EPA rules. If the change of exhaust allows even a little less back pressure then would it not run even leaner?? I would do the tuner no matter what, just to help my motor run cooler and last longer... If sound is your thing, do head pipes too, without the cat your bike will sound great and will also run cooler...

I was running 4" Rineharts on 2011 Ultra. Nice deep sound,and just a little louder than stock. But now I'm running v&h's dresser duals and dyno tuned with direct link, and it makes a big difference in the sound. The rineharts really bark when you open up the throttle. The rineharts sounded nice and mellow on my stock 96, but if you want the full sound of the Rineharts, you need to do full exhaust system. If your just putting slip on's on you don't need to do anything. I ran mine quite awhile with no problems before adding headers and dyno tune.

Running Samson Ovals (off bike traded in) on '11 Ultra Limited. No tuner.
Absolutely no problems.
Doing a full Stage 1 when I put it up for the winter.
American Custom catless headpipe, Dobeck Gen 4 tfi and Ness big sucker air box.
But as I said I rode all summer with the slip-ons and had no problems.
