cat removal

  1. Indian Chieftain
    I have 2019 Chieftain. Considering the rear engine deactivation, I have not yet experienced any major heat issues. However, I was wondering if de-catting (catalytic converter removal) would improve the exhaust note and performance.

    I'm curious how hard it is to remove the catalytic converter from my 2018 Roadmaster. Do I need new pipes or can it just be removed?

    My local dealer offers what they call an X Pipe that replaces the stock catalytic converter, etc for $359.10 wondering if I should go this route or just gut out, modify the stock cat? According to the dealership or should I say "stealership" they claim that I won't be getting better performance...

    Decided to reduce the amount of heat on my right leg with a surplus header pipe - have seen various methods - here is another one ... instead of opening it right up .. used a hole saw and pulled it out and welded back up again - what are your thoughts ??

    ok, I’ve read threads of guys with stage one indian slip ons without the cat and plug. Does anyone have a video or could make a video of that exhaust sound? This is with fiberglass wrap still in the pipe though. Just no cat, no plug. Appreciate it and very curious

    Ok, I am seriously considering gutting the cat on my 16 CDH. My question is, is there any down sides? Do I loose low end torque because of lack of back pressure? Sent from my iPhone using Tapatalk

    I removed my exhaust pipes and cut the back side and removed my catalic convertor, welded it back up and removed my O-2 Censors and capped them off....I ride in short pants most of the time, I live in Texas but currently working out of state.... Did not think about it at the time but I could...

    Have used drills and metal rod and have enough holes that a 3/8" rod has hard time finding a solid area. But how do I break it apart so I can pull it out !?!?!?

    Looking for someone who can gut the catalytic converter out of the stock exhaust head pipe of my 2017 Chieftain Dark Horse. I posted a prior thread asking about the best header pipe to use and almost everyone felt that it was best just to take the catalytic converter out of the stock pipe...

    I know that there is already a bunch of posts about de-catting the head pipe. What I could not find is information about possibly adding baffles to the exit pipes from the cat box. I did read a thread where Enzo added baffles to his mufflers when he de-catted his head pipe, but I am...

    Just wanted to share with everyone how I removed the CAT on mine 2017 RM. I thought about purchasing a header without a CAT, but decided to call the service department and schedule appointment until I was told the cost. So, I got creative and decided to drill the CAT out, YOUTUBE said the job...

    I had bought several sets of complete exhausts from new bikes that were going to complete aftermarket systems. So keeping the proginal on my bike until I finished at least one of these projects, I will share some thoughts. Drilling out the cat...............how in thee Hell do you all do it so...

    Hey folks, I have read lots of stuff on removing the cat and loss of back pressure and the pleasant bonus of heat reduction. Anyone ever just punch a bunch of holes through the cat? Think swiss cheese. It is bound to eliminate some heat and maintain some back pressure. I get the approach...
  17. Indian Motorcycle Tech Q & A
    Yes I've read the many, many threads on the heat issue but I post here to get opinions on what order to proceed in because I'm going to try three different things.....please rate, in order of effectiveness, what you think has the biggest impact on heat reduction. After recently having the...

    I decided to gut the CAT, but decide I wanted to try a little different plan. Cut Exhaust in half. Totally remove cat and put a diverter plate in between and make true duels. I haven't put it on yet. Waiting for 500 mile service to be completed Friday the 16th April. I will let forum know how it...
  19. Indian Motorcycle Tech Q & A
    I've been reading multiple threads about removing the catalytic convert material from the head pipe. Just when I'm convinced it'll be advantageous, I read a negative comment and change my mind. UPDATE: I finally got around to removing my CAT. I also added Cobra Quiet Core Baffles into the tail...

    I have stage 1, sounds great! If the content of the converter were "accidentally" of coarse, removed would the MPG improve?
