Default Anybody Regret removing cats?

I put hard lowers on last Fall, and I love the wind management. Now that it is hot out, I have the downside... I have read everything I can about heat management, and have tired all of the them, except removing the cats. I don't have that much of an issue riding solo (with the lower vents partially open), but I went for a ride with my wife over the weekend and she was MISERABLE. She said it felt like her skin was melting! I can remove the lowers, but then have the buffeting issue (don't want to go back to the Madstad).
I'm not trying to dabate the pros (less heat) or cons (emission compliance, loss of power), but get insight from those who have removed theirs.
Bottom line, would you do it again?

i never had much issue with heat, i pulled mine, and put them in to keep all the low end tq i could when i added cams. Kevinx just posted a pic of dyno comparisons between two basically identical bikes, one with and one without cats,, the drop in tq was pretty big without. with my tour lowers on and vents shut it stayes cooler then with them open. do you have any mods done, O2s unplugged, tuner,,etc?

Makes me wonder if your getting that much heat. If your running a tad bit lean.

What makes you think that removing the CATS will make the ENGINE run cooler?
Have you tried to run the bike RICH 'cause you know that will cool the engine, right?
Have you considered having the fins diamond cut 'cause that ALSO cools an engine off (it provides additional surface area).
Finally... remove the lowers (I removed my JTD hard lowers for the summer)

In your list of modifications in your signature, I didn't see anything related to a fuel controller. You may be running a bit lean which would cause very high temperatures. I was reading a few posts about removing the cats, and now I wish I never had because it feels like I lost some of the low end punch. It seems like the only way to add them back is to buy another crosspipe.

There was someone here who suggested thunder baffles and I wonder how they work

Kinda apples and oranges there. You swapped out for a set of Freedom True Duals. Not removing cats from Factory head pipe. Big difference

I'm not an asshole...I just type that way

I'm thinking three beers
