V & H dressor duals / ovals
I own a 2010 FLHR and when I bought it I changed out the stock mufflers to V&H ovals. The sound was a lot better and it did not seem to run any hotter. Today I am taking out the stock header and replacing it with the V&H dressor duals. The consenos of opinion from most people is that you can change mufflers or A/C without a tuner but not both. It got me thinking if changing out the head pipe with my ovals will still allow me to run without a tuner. All opinions would be greatly appreciated.

No problem.
What you're wanting to do is a good thing IMO. You will open up the air flow tremendously just by removing the cat. See the pic below of the converter cut in half and judge for yourself.

I changed from stock headers and Bub 7 Stealths to Dresser Duals and Monster Rounds.
The Monster Rounds have the same internals as the Monster Ovals.
I was waiting for the PCV to arrive and thought I could run it for a day or two without it, wrong. The bike ran extremely lean and had a skip in it. I am assuming the O2 sensors didn't like what they were reading in the exhaust.
Put the PCV on, loaded the map, made a couple of adjustments and off I went. The PCV is very close to perfect, but I opted to go with an Autotune module to get it exact. The bike is in the shop for a compensator, so I haven't had a chance to get it out. I'll post hopefully tomorrow about the Autotune.

Wow.....since we run 07 & 08's I read about the cat's you guys are dealing with but seeing it exposed is a whole different can-o-worms. When/if I ever move up a few years THAT will be the 1st thing out.
