Hi. I have a question. Has anyone removed the catalytic converter from an OEM muffler? How's it going?

I have a kawasaki versys 650, I've seen a mod that drills and removes the catalytic converter, but on a first generation Versys.

I heard my some of my friends removed the cat from OEM mufflers but I haven't done that. I'm not planning to do it anytime soon. I don't think it's gonna give you any life-changing performance gains unless you tune, and I can't risk the CEL issues that may come from it. Totes up to you. Let me know here if it works.
 
Just curious, what's your main reason for wanting to remove it? Are you looking for a different sound, more power, or just to reduce heat?
 
Havent done it myself, but Ive heard some folks remove the cat from the OEM muffler on a Versys 650 by drilling it out. It can improve flow, but it might affect emissions and noise levels too. Since youve seen it done on the first-gen, it's probably similar for yours
 
Possible yeah, but most people who do it on the 1st gen say it improves flow and sound. Just keep in mind it might affect emissions and could trigger warning lights or fail inspections depending on where you are. If you try it, make sure to check local laws and watch for any engine check lights after.
 
Been hearing guys do it but it's not very common from what i know. It could cause technical failures tho. If you go for it, make sure to follow local regulations and be ready to deal with any possible issues like everybody else say here
 
@quiznos22 Yeah, that's the thing, I mean it sounds great in theory until you get that check engine light blinking and looking at you. I guess it's worth weighing the "cool factor" against the hassle later. Are you willing to risk all the ease just for the sound?
