Thanks for the pics of the cat location and removal. Definitely didn't make it easy to get too.

Thats why most do the after market headers or buy them from some one who decats the headers. Either way, you need to get that heat down to make it a comfortable ride.
Before I did my one de cat, I thought flow was bad with them as most people do ... I actually rigged a pool flow meter to the pipe with the cat and again after removal of the cat. The difference was negligible, I'm not sure how accurate my test was, using a shop vac as a flow source ... but it looked cool ... LOL
As I understand it, it's the chemical "conversion" of toxic stuff (hydro carbons and such) to water that generates the heat, hence the material that causes the reaction, usually platinum, needs to be removed to stop the conversion.
The hardest part of the de cat process was making sure no loose "dust" left in the pipe. I took the pipe to a filter cleaning place and had them ultrasonically clean it after I got most of it out.
I was just talking to a guy after I made my last post. he has a nephew with a welding business. He thinks that the nephew could cut a pocket in the pipe and remove the cat for me. I have to wait until Monday to find out for sure though. Might be the way for me to go and the cost will be much less than buying a cat less pipe from someone.
2014 w/10K+ miles - I'm going to de-cat an extra new takeoff head-pipe I have. You all talk about how well the cat flows. I really don't understand why I would need a change in tune if I am keeping the stock mufflers and air cleaner. The system is designed to be able to compensate for changes in altitude (air density). I know of many people, including myself, who have made changes to their auto exhaust with no tuning ... and no ill effects.
I am considering either the nightrider FL-AF-XIED-10 http://sales.nightrider.com/fl-af-xied-10.html
or the FL-VIED-10 http://sales.nightrider.com/fl-vied-10.html
As I see them the difference is that the more expensive unit has the ability to richen from 14.6 to 13.6 where the cheaper unit is 14.6 to 14.4 to 14.0
I seriously doubt I will ever do any major mods (we are very happy with the stock performance ... just want less foot heat for the wife) .... and if I was to do major mods I would do everything correctly including a full blown tuner.
My question is .... which of the 2 units would you recommend as I've read here that most only go to the 50% setting or less.
Thanks,

Bob if thats all your doing then you do not have to tune. I did the de-cat on my neighbors trike only nothing else done and he is happy with it. Runs great and like all ready mentioned a little deeper muffler sound. Have fun Ted
So if I understand correctly, I can just decat the header with everything else being stock and not have to tune?
Yes that is correct.
Excellent. *Can I also assume that the same would apply to adding just a Fullsac header pipe, all else being stock?
The fullsac might be a little freer flowing, but I'd think you'd be okay as long as the pipe you use is a 2-1-2. Probably be cheaper to get a decatted pipe. With the flush you'd need the adapters right?
Wild pigs has a de cat head pipe for tri glide for $150.$50 return your stock pipe.On Ebay
A buddy bought these, the chrome was in terrible shape.
