I have a 2011 ultra classic was wondering if anybody is running just slip ons with no other mods didn't know if that's something you could do without a tuner or air filter kit thanks

 

I have a '11 Ultra Limited. I had the dealer swap my Samson Ovals off my trade-in and did not do anything else. The bike runs fine and the tech. said the engine will self adjust with such a minor change.

I haven't done anything else because I wanted to look (and hear) around to see what exhaust system I wanted.
I'll be doing a complete Stage 1 over the winter.

You'll run fine until you get into the A/C changes
