no cat with stock mufflers
I like quiet, but wouldn't argue with cooler temps and a bit more power from going catless (ok a little more sound would be nice too). So I want go catless while still using the stock mufflers. Any suggestions?
Oh yea, and I want to keep the stock cat just in case...
My bike is a 2013 FLHP, police.

Headers that came with cats make more power than ones that have had the cats removed. It's all about how a pipe scavenges the exhaust flow.
Want a tad bit more power, buy a pipe, as has been mentioned above.
Reason to get rid of a cat pipe may be heat and heat only. Too many here are still stuck in the 70s. Cats today flow very very well. Need proof, go to the car world and show me ANY cat replacement pipes being sold, like they had in the 70's. What were those called??? Test pipes. Put a set on my 78 Magnum.
I rarely ever get a bike in here with cats in them. I will be trying to document the loss on the next one thru.

Maybe it's because I ride a Road King without lowers to impede the dissipation of the heat, but I am skeptical that there is even a noticeable heat reduction when the cat is removed. (I've never seen measurements.) The only place I have ever felt heat is on my right inner thigh and that comes from the rear jug and header far before the cat. I've never felt heat on my foot or lower leg and neither has my wife. My feeling is that I am straddling a 103 cubic inch air cooled internal combustion engine and there is no way to make it "cool."

You are right, of course, but I doubt very many will believe you. It's one of those things that, if repeated often enough, becomes true. Most here are convinced that (a) the cat is restrictive, and (b) removing it will generate more power. Neither is true, but I think you're beating your head against the wall.
