I'd like to hear from some of you that have removed your converter. Was it worth it? Does it have to be reflashed? Any complications from it? Less heat? Warranty issues? etc But most of all would you do it again if you bought another new one today? Thnx

For me the choice was mostly cosmetic to go with the catless headers. I personally don't notice the heat difference. The only thing I really do notice is the signature straight pipe sound.
Other than perhaps reducing the heat, which most says it does on the H-D's, what would be the point? I'll cut mine out in a heartbeat if I feel it would reduce the heat. JMHO
I would let the cat in place, if equipped from factory.
Why?
Its a better feelig for me to say that Volkswagen is the bad boy, the devil himself in the big game of emmissions....
On the other side, so Chinas industrie is rising, the perfect sound without converter is the best reason for removing it.[emoji106] [emoji6]

I hollowed my cat converter out about 300 miles ago.
The result was a significant drop in heat on the right side of the bike. I gave it a real test in gridlock traffic, 103 degrees outside, was in bumper to bumper traffic barely moving for about 2 hours.
A slight change in sound, no louder, just different.
No noticable change in performance.
No change in fuel economy.

Good info. I did the same on my '06 Kingpin years ago. Found the cats to be right at the end of the head pipes when I took the mufflers off.. I trust that's about where they are on the Chieftain as well?? Hole saw took them right out. Any help you might be willing to share will be appreciated.

Not an easy task but well worth it. noticeable less heat. different sound, more torque. took me 3 hours of drilling did not pull cat off.
Do aftermarket slip ons or full exhaust systems come with no Cat of are they required not to alter it or in the case of full systems, remove it?
When I was at the dealer Saturday they told me they would cut the pipe in half and remove the cat they wanted 500 bucks for parts and labor. On my Harley that I traded in I cut a window in the cat gutted out the honeycomb and welded it back up. The only difference I noticed was a huge reduction in heat and a deeper tone with about 10 percent increase in volume. The pipe set up on the Indians is the same as a Harley and would expect the same results. I'm gonna gut mine as soon as I get a few hours of free time.
Cats provide back pressure as well as reduced emissions. Back pressure builds more torque through better fuel burn.
More torque is more better! ;-)
Any reduction in back pressure on these engines will reduce torque, unless aided by other engine mods.
Since a cat reduces emissions via a heat catalyzed chemical reaction, naturally heat is reduced when a cat is removed.

Wrong, the cat on these machines flows so well that removing it doesn't change the back pressure at all. The only thing you will notice is the heat reduction.

Since my Chief Classic sounds great as it is, and I've never noticed any excessive heat from the engine area, I cannot see any advantages in removing or changing anything in my bike's stock exhaust system.
look at Fuelmoto for their jackpot header, plenty of info on the forum. It's a cat delete pipe and not to difficult to install.
Well what is the car benefiting from a cat?? ABSOLUTELY NOTHING! As a matter of fact it's the engine worst enemy! I removed my from my car.. Better response, 40% lower heat, less strain on engine, better performance (more bhp), better fuel efficiency... need I say more?
It really only matters in areas that have mandatory emission tests. Luckily I don't live anywhere near such a place.
