Default Stock slip ons, 2017 FLSTC

What would work better for removing heat and making this stock 17' FLSTC exhaust louder ?
Remove the cats, or remove the baffles?

I'm considering one of these two options since I might be able to get my hands on a free set of stock slip ons to experiment with.
Anyone tried?
Thanks

I have looked into American custom exhaust, that is an option.
Doing it myself is the option I'm leaning towards. The slip ons are free, so if I make a boo boo, then it's not a big deal.
I was just trying to hear if someone had took cats out vs. Baffles or both, and what their experience was with either way.

Still going to run lean and produce heat till you put on some sort of fuel management system. My opinion is do a complete stage 1.

Do you mean a dealer flash?
I was looking at the screaming eagle pro street tuner.

A stage one consists of the tuner, such as the street tuner you're talking about, a free-flowing air cleaner, and less restrictive flowing pipes, all three equal a stage one, this will make your bike run cooler, sound much better and perform better.

If you modify the stock mufflers, you will not be happy with the sound or performance. The best value is American Custom Exhaust mod to include the street friendly baffles, a V&H Fp3 tuner, and a K&N air filter. You can do this complete upgrade yourself under 3 hrs. About $550.00 total. The bike will run well, good mpg, cooler and an adjustable sound.
If you plan on doing cams etc in the future, that's a different conversation.

I just bought a 2017, and there's a couple things you need to consider. The way I understand it, If you put on any other tuner than the Harley Davidson tuner, you will likely void your warranty. A turner ties into the ECM, a non Harley component will likely cause you waranty problems. Also, if you remove your header pipes you will definitely void your warranty. To be on the safe side, I'm having the Harley Davidson dealership install the Harley Davidson Street tuner, and I'm putting on Vance and Hines big shot slip on mufflers, leaving the header alone. Remember, on the softails a catalytic converter is in the mufflers so you lose that when you change your pipes. You can do whatever you feel comfortable doing, but for me going this route in ensuring the warranty stays intact made the most sense. Even if you have to spend a few hundred dollars more, it's better than losing your factory warranty for the next two years. Ride safe

The whole head pipe thing has to do with the touring models not the softail. The catalytic converter is in the head pipe on touring models and in the mufflers on a softail. Removing the mufflers on a softail is equivalent to removing the head pipe on a touring model.

Exactly sparky357. That's why I could not understand why my dealer has no trouble exchanging the mufflers but said he cannot do the headers. I have a question for you. The stock headers run one pipe above my rear passenger peg and one pipe below it. The Vance & Hines headers put both pipes below the rear passenger peg. I should simply be able to change the header pipe myself and use the same mufflers to get the relocation of my pipes, correct? Should not need to retune or anything?
