Thanks for this. Just finished up a 23' 890 Adventure. A few notes which may be 23' specific. If you are re-using the original bolt that held the cat on to secure the mid pipe it's 15 Nm. The shift rod bolt is 10 Nm. The 3 T-45 for the footrest bracket side stand all need loctite. I wasn't able to get to the right side cat bolt behind the brake lever with a ratchet and socket and had to use a 10mm open end ratchet.
thanks
Excellent job old chap! Very thorough. Glad you gave us the weight saving - it's one of the two most important things 👍🏼😀
Thanks Mario I appreciate it. Installed mine last night in less than an hour thanks to you! Happy riding my friend
Glad I could help
Fantastic work. Thanks for sharing all the details. We all make mistakes so I appreciate you showing us the gasket miss.
Great video series on790/890 upgrades; super appreciate all you do. 🏁🤙
Great informative post! Good technique, great technician!👏🏻👏🏻👏🏻
Lots to do for such a simple swap over. But you’ve covered it extremely well. Excellent
Yea, fortunately, it's one and done.
Thanks for the video. 👍installed the decat and intake. Huge improvement!
Second time through the video, sealed the deal for me. Thanks!
Just did 500 miles with my arrow and put my akro baffle back in. Instantly relieved my ears. Sounds dope with a straight system, but when you have a long trip or several days ahead, it still sounds good and keep the twin drone a bit. Stock muffler probably is great on the ears and still sounds cool.
I agree, heat is way down. Keeps excess heat off the rear shock too, which has been known to fail early from CAT heat.
Appreciate the insight, Jordan! Realize the stock muffler doesn't sound "as" good but I'm a cheap bastard 😂 Another good point on the car and shock failure which is why I wanted to get out in front of it.
Thanks Mario, great video as all the Back in the Garage series are.
Thanks!
Informative and easy to follow instructions. Love thre grunt without the cat and will look into removing mine when my bike comes next week :)
Thank you!
Nice job as always 👍🏽
Again another reason why I subscribed to your channel.
Nice. Doing the same install this weekend. Yours sounds way better without the cat and has me really looking forward to mine with the Akrapovic.
Yeah, with the Akra I'm sure it would sound even better.
Any feedback with the Akrapovic? :)
You do a great job with your tutorials.......
Great DIY post! Any reason to not use a thread locker on the bolts? Thanks!
Excellent video. Thank you for filming and posting. You still happy with the CAT delete? Any issues? Looking to do the same for my 890R over winter.
Good job Mario, pretty big job .
IMO way more work than it should be but really like the outcome.
Very clear instructions. You’re videos are my go to for maintenance on my 790. Thanks mate. I appreciate the work you put into this.
Glad they’re helpful!
One thing to remember is that a change of 3dB either doubles or halves the sound pressure depending if it's going up or down.
Anthony
Thanks!! You have saved me hours (maybe days)
It was fun trying to find all the bolts when installing on Pete’s 901
Thank you for the video I haven't read all the replies but I was curious if you have to do anything to turn off an engine light or remap it in any way because now you're bypassing the O2 sensor by the way I see it thank you
I am looking at doing this on mine, is there any issues caused by decat? Do we need to have it mapped etc? Mine is running the Remus end can and sounds great already.
Do I need to reprogram anything after changing the exhaust or exhaust with decat??
Hi Mario, I wanted to ask you, if the de-cat you have mounted, what does it have inside the largest duameter section? Thanks so much and forgive my english, i used the translator. Danilo
Your shop videos are helpful and impressive… sometimes I just watch them for the education factor.
I traded my 1290 for a Standard 890 Adventure the other day. Don’t know if I’ll replace the cat, maybe…
Thanks again for great videos.
Glad you find them helpful
Great video!
One question: do you need to remap the engine software after deleting cat?
Why I'm a fan of the Sharon exhaust from Rade Garage, keeps the heat out of there away from the shock...shocks do not like heat, especially the 390 ADV
Do you have to remap or tune the bike after installing the cat delete?
Was there any tuning needed afterwards? If not, please explain so that I would understand 😢.
Well done!
Great video
Sounds way better without the cat
Great Video. Where do you get torque specs and other various mechanical information on this kind of bike? User manuals seem to be lacking a lot of technical detail. Is there a way to get shop books/ information or something for more technical, say wiring diagrams or other various details?
You need the service manual for all of that information. Best place to get one is print.ktm.com/
oh that sound is sweeeet!!!
THANK YOU FOR ALL THE INFO, VERY HELPFUL. I M ON THE MARKET FOR 2023, BUY THE KTM 890 ADVENTURE 2023. ABOUT THE SWINGARM SCREW AT 100NM DO YOU PUT BLUE LOCKTITE....
yes
Great video
I have a 2019 790 & will be doing this same mod, is there any software u nesd to change or remap after this?
I just went out and looked at my Cat sitting on the shelf! Still had the gasket on it lol! only 9k miles later...
Did you need remap , sport air filtre and ecu flash ???
Great video sir........Just one question. There is no special tuning needed when deleting?
I have the same question. I feel it runs quite lean from the factory. Considering this and a tune but curious about the finding here.
So what is the point besides the weigh.
Is there any other benefit ?
Thanks, I appreciate your videos. Once I do this will the factory mapping still work fine or do I need to add a power commander and a tune?
It’ll work fine
Engine performsnce has improved? How It effect at lower rpm, the engine lose torque, fluidity? Many thanks
Hey Mario, I really enjoy all your videos. Question removing the Cat, Is there any "Check Engine lite thrown? Did you first need a Tuner?
Nope
Another good reason to re-use the torx bolt is that the allen bolthead is too big and youy cant get the footpeg bracket back on....ask me how I know!!!
Love that rasp! Did the prices go up dramatically on this piece. You said $240 in your video and I just paid $340...
Great video, I love my 890, however this heat that radiates out is unbearable especially in Las Vegas. So all I need is that arrow midpipe? And you truly noticed a heat difference? Because I’m thinking about getting a new bike due to this heat. Thx
There's a noticeable reduction in heat. Also, I don't know what your riding gear consists of, but a quality pair of riding pants due wonders in keeping your legs from cooking.
I'm not complaining about the heat since I wear a good pair of riding pants. That said, if you don't have your feet in tight and legs up against the frame, you don't have proper control of the bike. (aside from cornering when you need to weight the outside of the peg)
Hi since you've had it on there awhile, have you ended up with any exhaust leaks? Great how to video
No
Will the mid pipe void the factory warranty? Wonderful garage video as always. Bike definitely sounds better now.
As with any modification (in the US) the warranty is only voided if the modification can be shown to have caused the problem. e.g. if the tft display dies they have to fix it because the mid pipe didn’t cause that. It’s only a year warranty on the bike and mine was already out anyway
Hi from Greece! Did you notice any change in fuel consumption after cat delete? Are you going to change the air filter too? Thanks and keep doing so cool videos for us!
I don’t track fuel consumption but haven’t noticed any negative effects.
I’ve changed the entire airbox and filter. There’s a playlist on this channel of nothing but 890 videos to include it.
Hi I am getting my new 890 duke r on Saturday and want to put a decat pipe on. Does this need mapped after install? Or runs fine just with decat fitted??
Assuming no other major mods, no remap is required.
Hello, excellent video, I have a problem I am trying to do it to my 2024 Husqvarna expedition and suddenly appear a O2 sensor in the catalytic, so I need your help do you know the model for the bypass to eliminate this O2 sensor, thank you
I’m sure the aftermarket will come up with a solution soon.
did you happen to think to heat wrap that midpipe? I am putting on a similar midpipe swap and am thinking of wrapping mine...also installing the plate between that hot area and the rear shock. Thoughts????
No. The cat is what gets hot. Once it's removed the midpipe is much cooler.
Quick question,,, I removed my catalytic converter and did the same as you,, left the gasket on the cat.
I couldn’t understand what I’d done wrong, found your video,, and thanks.
But my question,,, how did you get the gasket off the cat??
Just used a small screw driver to work the edge and then it’ll slip off
Great video, did you remap the ECU. It it something that needs to be done?
I haven’t. But you can
Hey Mario, how did you find the heat issue, any significant improvement? How about performance, any issues with popping or backfire on the overrun? Lastly, any issues at low throttle or low revs? Thanks.
Ask the owner of Wings Exhaust why he doesn't sell these cat deletes. He will confirm exactly what you said above.
@@RayzGarage cheers, I still haven't installed one with my Wings exhaust as I suspect there might be issues. I would prefer a 1st hand experience before completely ruling it out. It is Summer here now and when the temp gets really hot, the exhaust heat from the cat gets quite uncomfortable in traffic.
@@ride4adventure got me.... That's what caused me to contact the owner of Wings for his advice. I stand by my decision to leave it in
Great video!
I did the same installation to my bike but I have a problem. After 5 kilometers test run my engine was stalled and it won’t start again. I have to pushed my bike home and replace the decat mid pipe to the stock catalyzer pipe. And when I start the bike it only runs for 130 seconds and stopped. I don’t understand which step I did wrong…Do you have any idea?
Does it sound decent when it runs, do you hear anything different. Something might be shot.
I'd do it just for the sound and heat. With a 1290 it already has more power than I'll ever need and if I was concerned about weight on the bike I'd eat less. Thanks.
Does sound a helluva lot better.
Mario I followed your vid and installed my Arrow Mid-pipe today. All is good, no leaks at all… But one thing I wasn’t clear on is the tab on the mid pipe and how it attaches to the small frame tab that comes down. I just had issues trying to figure out how to make that solid so I can torque it to the 25 Newton meters. Ultimately I used one of those black spacers put that on the outside. I’m not 100% happy with that connection. I mean it is solid and I’m sure it’s fine but it just wasn’t as neat and clean as I would’ve liked it to be. Any suggestions on that? Thank you.
Sounds like you've got it tweaked a bit. Loosen the exhaust clamps on both ends to release the pressure, then try again. Shouldn't need any sort of spacers to fasten.
@@2WR ok I’ll do that. Thx
thx for the video. did you notice any less heat after the cat delete? any other improvements or cons? thx
Always riding on riding pants and off-road/ dirt bike boots so I’ve never noticed any heat to begin with. Biggest pros are the bike no longer sounds like a bunch of bolts rattling around in the crank case and it has better pick up low to mid range.
@@2WR thx. you near charles town, wv by any chance?
15-20 min away
Good job, I wonder if it does need retune the ECU ?
If you want to FULLY maximize performance, yes. That said, it's not require and you'll still realize some gains from it (aside from weight savings) if you don't.
@@2WR thanks 🙏🏻
@@2WR Do you have a recommended flash or tune you recommend?
Any time you remove the catalytic converter on a vehicle you should get the engine tuned to adjust airfuel ratios for the higher flow rates. If you are removing the Catalytic converter it is also suggested to get a high flow airfilter aswell.
Are you planning to change the exhaust can with a slip on? Would seem to add more to sound, and possibly save some more weight.
No, I’m gonna leave the stock can. Check out the video we did on the Norden 901 exhaust. All the weight savings data is shared on that one.
@@2WRhi, from italy. Is there difference from a totally empty decat, or one like that you mounted in this video? Because I have a totally straight decat..without the little decat you have in your, i mean...and did you a map after this installation?
Any concerns about running to lean? Thanks
Nah, (obviously something I'll keep and eye on) but shouldn't require a remap.
Off-road or on the road air is everywhere so why is it such a violation to run the new mod anywhere for that matter and I think it’s more of a safety hazard with that stupid hot cat can under your seat and ready to melt out the seals in the shock to blow out the shock and cause ride ability issues! I’m all in for this cat delete mod and great video!!!
measure at your cat and at the exhaust outlet. The cat is not actually that hot.
@@mojoriden it puts out a ton of heat all over it with no where to go but your rear suspension and left leg. there's nothing else down there to create the heat but the cat.
Was there and performance gains? Easier revving motor?
Other than weight savings, no real performance gains. Sounds a helluva lot better and got rid of some of the heat.
How does the cat delete affect the power below 3000 rpm?
Under 3k RPM, I haven't notice any difference (from my butt dyno). As I stated in my video, I really did this to lower weight and heat. There have only been positive performance impact (video coming soon) and no negatives.
Re-flash needed ??
The clamp that goes on the midpipe and the engine pipe just will not line up, the engine block itself is not giving the clamp enough clearance. Did you have any issues with this? Spent the last 4 hours trying to get this clamp on and it will not fit.
I’ve installed 3 of these on 3 different 890/901s and didn’t have that issue on any.
Mario, I have 2023 890 Adventure R. I've been seeing a lot engine failures related to cams. Did the removal of the cat help with cooling?
Also did it run better?
Ciao, sto vedendo anch’io se mettere il decat arrow. Domandina: perché ha quella formo di “bambolotto”, c’è della lana di vetro all interno o è libero? Perché ha questa forma e non quella a “S”? Grazie in anticipo
It has a built in packing core.
Think im going to go for the sc project and get rid of the cat 🐈
You have to remap it?
I have owned other bikes with a cat in the pipe and simply drilled the cat out using spade bits. On another bike I simply cut open a window on the side of the pipe and removed the cat. Then rewelded the piece back. Any reason no one does this with these bikes? If the pipes are stainless than I understand that takes a different welder.
1. drilling out the cat means you can never restore the bike if needed.
2. Arrow mid pipe weighs several kGs less than the cat, and it’s smaller which creates more space between shock and pipe
3. Few people can weld or have access to welding gear.
4. Arrow mid pipe looks professional grade. A cut out and welded cat won’t
@@TapleyBS Makes sense and good enough reasons for most. For me:
1) The cut can easily be located in an area not visible, its just a small window.
Also, the pipes I cut have heat shields, can not see the welds.
2) A couple pounds in weight savings on a ~500 lb bike when gps, bags, tools... are added can be accomplished with rider losing some weight. lol No one will notice a couple pounds low on the bike anyway. The 890 weighs 12 lbs more than the 790 and no one ever mentions it.
3) Pipe heat shield to protect the shock would be better and are cheap.
4) $400 savings, I'd rather remove. But hey, I'm cheap and a diy'er.
Sounds stupid asf
So, by changing the mid pipe wont that require a new jet tuner?
I was about to ask the same question. I’d be interested to know what are your thoughts on that Mario!
If you want to FULLY maximize performance, yes. That said, it's not require and you'll still realize some gains from it (aside from weight savings) if you don't.
Did you have to do anything to the electricals so there wasn't a warning light?
No
Any warning lights triggered, by the delete?
No
Mario, quick question please...thoughts on KTM engines are already tuned high for performance...my concern is that a d cat will further tune the engine to the side which may put additional stress on the engine longer term? In your opinion is that fair, or would you disagree? thanx appreciate the comments!
It puts no added stress on the engine. It’s simply removing a restriction on the exhaust.
@@2WR great Thanx!! However, like you say it is illegal on the road hey??
@@Gorilladome4664its completely illegal
Just put the Leo Vince version of this pipe on. My bike sounds much better at idle and under throttle, and not to mention a lot more room around the new pipe for cleaning.
how do you remove gasket flange from stock catalitic converter
Slide it off
@@2WR great, thanks for teh help
Hi
What bike stand are you using?
Pitbull
Sounded much better with the delete
HUGE difference! And agree, for the better.
@@2WR I may do the same with my tenere
Do you huave a video with the arrow sleep on….?
No. Have a video putting an Akro on a Norden 901
@@2WR ok… I wanted to hear the sound of the arrow exhaust but it’s ok 👍🏻
What about factory warranty ?
Bike’s over a year old. No warranty.
Do we loose fuel mileage??
No
Can anyone comment about removing the cat leading to being too lean and a service light that knocks out cruise control?
Brent, short answer is "it could." That said, haven't had any issues. Is the service light question a separate question? If you turn off MTC, cruise control will not function. It will also not function if your ABS Sensor/Wheel Speed sensors are disconnected or faulty.
CC works fine on mind. My bike is in the shop having the cams replaced. Trying to puzzle out what happened to the cams. Mechanic said probably high heat or improper manufacturing.
@@garyib7200CC removing should be generate additional engine heat due to leaner carburation, so maybe generate additional stress to cams. Thats why Is often recommended to remap when CC Is removed
Should generate additional heat* im italian, made a language mistake
No need to remap when removing a cat?
No
Mapping??
At 16:08 the torque setting for the silencer is 25nm not 15nm, as per repair manual🤷♂️
You’re correct about the torque spec (I don’t actually use a torque wrench on the silencer bolt) but wrong about the timestamp.
I have a 890 R 2022 , I do have the Rottweiler intake . If i do this will it require a tune?
No
Where is sound test bro ? 😃🔊🎶🏍💨
Too bad you didnt take any temperature measurements before and after.
That’s a good idea. Actually just picked up an infrared thermometer today so I’ll try to get a test ran soon and post an updated video.
I've "deleted" a few cats as well with my cat trap.
Oh not that sort of cat.
I will see myself out.
😂👍
You can not measure DB in a garage … and not with you phone.
What was your day job before being a UA-camr?
While I make UA-cam videos, I also work full-time. Don’t like to mix the 2 on my channel but a quick Google search and you’ll find me.
Why delete the cat for a mere weight savings of 4 lbs.? Just delete the sub and soda you have in your tailbag and take a crap before you go riding. The euro 5 emissions software on the 2021+ is inclusive of the cat in place and incorporated into the ECU. The lack of a cat will make the bike stumble at high revs. I was told by a pipe manufacturer after multiple runs on the Dyno that a cat delete actually hinders the performance and certainly kills the warranty. Personally, I would not alter the performance of my bike over 4 lb and a little extra heat that I've never felt on my 890 ADV anyway. Just IMHO! However, congrats on your very informative how-to video for those that dont care about performence and value loud pipes.
May want to familiarize yourself with the Magnuson-Moss Warranty Act. But yes, the rest is “just your opinion.”
@@2WR I know it's been a month but thanks for that information about warrenties. It states that the consumer is allowed to add aftermarket parts and can't be denied warranty coverage unless the manufacturer can prove that this modification was the cause of the problem. It sounds as complicated as the warranty itself, lol. To each his own. I was strongly advised by a pipe manufacturer not to do it so I decided to deal with the extra 4 lb.
This group is for learning so I thank you for providing me with that educational information. I might be able to use it someday. Brapppp!
it may be different on the Norden Expedition, but the heat delete will save my rear suspension and left leg. I don't care about the weight.
