Removing the catalytic converter from the factory header so it will shoot flames, spit fire, and breath better. This worked well with our slip on exhaust and link pipe, it's as close as you can get to a full exhaust system without shelling out the cash. Cheap option that worked as we wanted it to, no performance gains just from this, but we couldn't notice any power loss or a dip in the low and midrange torque. I'm unsure at this point if we will get an ecu flash or need a tune. Maybe down the road with more mods we will get it flashed but for now, it runs perfect with no sign of running too lean. Comment with any questions. Look up our other videos for the full review of this bike and the removal and installation of our exhaust. I also answer questions about a servo buddy, check engine light, clearing any cel light, and more. Enjoy!

Couple thoughts; get a ball joint removal tool aka pickle fork (way cheap at Harbor Freight) drill two holes in the cat the size and spacing to get the tool forks in there. Attach a pair of big vice grips on the tool and twist the cat material out. This worked on the pre 2024 ZX6R, but the new pucks look a lot thicker. Also, once you gut the cat you have created an expansion chamber, in effect another muffler, that's why the tone changed, and what you lost in restriction you gained in back pressure with the expansion chamber. One cancels out the other. Some people hate the sound after the cat is gutted, the scream is gone and the tone is too mellow for their tastes. But to each his own. In other bikes I have de-catted, after a tune the bike comes "on the cam" at a much lower RPM; more bottom end power. Highly recommend a tune/flash after any de-cat.

@dinoelasz6360 3 месяца назад

I straight piped mine and added a fuel controller, and I noticed more power near the redline, but less power below 5000rpm

@bikesandbangs 3 месяца назад

Sounds like you need just a little back pressure to get that low rpm power back

@Young937phoenix 4 месяца назад

I just bought the M4 street slayer and it’s coming right off just like yours is. So I can cut that out and I won’t need a tune and it won’t throw engine codes. I’m kinda curious because I do plan on tuning it but if I can just do this for the mean time and get that pop like I want plus it just sounds better.

@bikesandbangs 4 месяца назад

Yeah as far as a cheap way to get the perks of a full system without spending the cash this seems to work good. I'll probably get mine tuned here sometime but with it running perfect without it, I'm not really in any hurry

@xdsmurfie 2 месяца назад

Not very “start to finish.” How did you get the edge pieces out after u removed the majority of the center?

@domshady96 28 дней назад

Is it me or were you shortshifting like crazy? You still had plenty of powerband to go in each gear before you had to shift. My ‘23 gets over 100mph in 3rd. By the time I hit 6th I’m going 140.

@devionaustin3696 3 месяца назад

Are you still on stock tune? Can I do this can keep it this way until I decide to get it tuned?

@bikesandbangs 3 месяца назад

I am still on a stock tune, not flashed yet. I feel like my link pipe adds just enough back pressure to make this setup work fine. I can't find or tell any adverse affects. What slip on exhaust and link pipe do you have?

@OhhThatsBeezy Месяц назад

Nice bike man. Are you keeping this one forever?

It's tough to call. I don't have a plan to get rid of it, is what I'll say lol

Im so tempted to do this on my 2024 zx6r but just by watching you do it, I'm kinda thinking twice already. Those honeycomb looking foil looks like a bitch to take out.

@bikesandbangs 3 месяца назад

It is, no doubt about that. This is why I wanted to make a video about it, so people had an idea of what they were getting into if they decided to do this. It's not impossible but it is more labor intensive than I initially thought

@yeysbaws 3 месяца назад

@@bikesandbangs and I also saw some vids that they removed the side fairing and the entire exhaust system, and there's no way I'm going through all that, I love tinkering with my bike, but I think this is not worth tinkering with! Thanks for the content!

I gave it a shot and failed miserably. After 2 hours of hard core drilling, hammering and chiseling I gave up. Took the headers to the local muffler shop and they cut out the cat and welded a 2.5 inch straight pipe. BEST $50 I EVER SPENT! Thanks for the video, great content!

After the flash you can unplug it without needing a servo buddy or anything. Mine is still in there and plugged in. I suppose I could remove that anytime

@FreddyKings87 4 месяца назад

Once you de-cat the bike, consider it a full system and get a tune.. imo

@bikesandbangs 4 месяца назад

Depending on your setup, yes. I think the only thing keeping us from running as lean as everyone else is that goofy 360 link pipe, which I haven't seen anyone else use. I'm planning too, maybe next week. Probably have Mooremafia or 2wdw do it

@FreddyKings87 4 месяца назад

@thegreataepshow4311 2 месяца назад

I hear u but that’s not exactly right. That small converter is probably worth 200 bucks at best. If he wants to cut that section of pipe out, he would have to have a new section welded on. Or he wouldn’t be able to put on a slip on exhaust and would need to buy a full exhaust. Both of those options would cost more than he would get from selling that catalytic converter. Hope that clears up any misunderstanding.
