I left the cat in put on rinehart and the XIED's , bike runs great and cooler and my wife doesn't complain about a hot foot, I have a 2010 SG 2 into 1, 120 bucks for XIED's, it's worth the try, if it doesn't work for ya they are easy to sell.

Before I removed my cat, I felt a concentration of heat radiating from that area. After removing my cats, that area of high heat is no longer there. However, I do seem to notice more heat on the back of my right thigh now. Maybe it was there before and I just never noticed it because of the excessive cat area heat.

hey thanks guys for all the input, I didn't mean to start a great debate!! I know there is going to be heat, just like your hair is going to blow! however my concern was that now after de cat heat is worse, now having read every ones response I now have a better understanding of things, and have decided to try some xieds, sounds like a lot of good feedback with these. thanks again to all

What I got was a little cooler (mostly for my wife), little deeper sound, little louder sound. IMO, there are shortcuts, but only to a point. Decat is all I'm going to do right now. Xieds worked fine for me. If I do anything else, I'll re visit the Xieds. I would like to add a K&N air filter and down the line some Monster Rounds. I don't know if the Xied will handle that. But I'll find out.

Agreed, any missing pets in the neighborhood? It really doesn't make any sense.

My bottom line.
With stock hearder and mufflers my 2011 103 ran 445 degrees at the cat area of the header and the bike ran great. With slip on's the area ran 445 degrees and the bike ran great. With a de-catted head pipe the area ran 275 degrees and the bike still runs great. If it wasn't for the heat, I would not have de-catted but there is no way that area will run hotter without the cat. De-catting the pipe should change nothing but the heat.

My 2010 Ultra is a pleasure to ride in stop and go traffic now that it is has slip-ons, Stage I, and no CAT.

Sorry, I don't buy that. Prior to the download, my bike would struggle to hit 100 mph. And like I mentioned, it would cut the rear cylinder quickly when in stop and go traffic or at long lights. After the download, the bike doesn't cut the rear cylinder nearly as fast, and now easily reaches 115 mph. And a side benefit that I hadn't counted on, I now get 2 mpg more than previously.
My SG has never been over 117 mph according to gps, the speedo was buried, and that was with a long, straight, downhill grade. I have a mod or two above stage one.
All my buddies behind me said they were going 120 mph and I was still pulling away hard.
I know it's all about comparisons. Anything over 100 mph is pretty darn fast, especially on a Harley. I just get a little tired of everyone that tells me their bike will run 120 mph when I leave them in the dust when I am only doing 100 mph.
Not trying to be disrespectful, but ride a bike that will easily cruise at 180 mph and you'll see speed a little different.
