[@remonsabuz7649]

Bruh where was this video when I needed it? You literally touched base on everything I had in mind. Great video g

[@MotoMedicine904]

Appreciate the feedback

[@patrik5428]

I took all of that out, full akrapovic exhaust system... sound is next level

[@kal1385]

Share ur insta....will hear it

[@caluzzucarrazzi5549]

really awesome trick with that ratchet wrench allen key combo

[@terryfiic]

great content! was exactly what I was looking for. the sound became more bassy love it

[@MotoMedicine904]

Thank you for watching. More stuff to come! 😁

[@TheAusherGuy]

Any performance benefits to the cat delete?

[@THEPRASANNARAO7]

Ecu reflash okay? After deleting decat??

[@xanders9767]

I just cant seem to get it in place the cat keeps on getting stuck on the shock and if the fit is good i cant seem to line up the box with the bolts

[@MotoMedicine904]

I had to use a small car jack under the black resonator box to get it back in place. It's tough but it will happen

[@massimo3860]

i once did a full delete, cat and black box, it was too much, too loud and im not exaggerating, even with my helmet on it was kinda painfull to ride, how is it now?

[@jamesjay1987]

I got 2016 390 bs3 I have in box high flow air filter + decat + midpipe + sc project moto gp exhaust with universal catalytic silencer + rapid bike easy afr module. My bike's low end rpm's more alive but my top speed decreased from 175 to 155-160. How about yours?

[@Tryneditjfan]

Can you do a video with a ktm duke 125-390 2021 model. Remove the decat?

[@ChapaChapa13]

I already have a FuelX lite from Powertronics, will that work if I do a cat delete or no I need an ECU?

[@47sha]

Does removing baffle from stock exhaust will harm my engine and produce less poweroutput?

[@MotoMedicine904]

No

[@THEPRASANNARAO7]

After deleting the cat what if don’t remap my ecu what will happen??

[@MotoMedicine904]

Then the bike is at risk of running too lean and may eventually blow up

[@THEPRASANNARAO7]

@@MotoMedicine904 Evan with stock exhaust??

[@THEPRASANNARAO7]

@@MotoMedicine904 i don’t have a money for that 😪

[@YashBhawar]

Will it harm my bike if i replace the cat section with full mid pipe and keeping the stock exhaust in ?

[@MotoMedicine904]

Not immediately...but a tune will be highly recommended.

[@YashBhawar]

MotoMedicine thanks buddy this info helped and yes keep posting such informative videos ✌🏻

[@RookieRay]

I never realised how close the shock is to the pre silencer chamber. It must cop come heat

[@MotoMedicine904]

They're very close together. Maybe 1/2 an inch. A lot of people who delete the pre-silencer wrap their new pipe with exhaust tape to help mitigate some of that heat.

[@gekolizzard]

On the South African model there’s a shield between the pre silencer and the shock.

[@jirizurek9685]

Do I need to remap my fuelmaps or something? I consider getting rid of the cat as well.

[@alierten207]

on coober's de-cat pipe they say ıt is not neccesary, ıt can usable without remap or piggyback.

[@kal1385]

Hi bro....instead of buying new link pipe you can also drill out catalytic converter.....!! Out of stock pipe rt??

[@agpasusu1698]

Yo Moto Medicine I have a question ! I am running a similar setup like your but I don't have a cat delete , I just have a powertronic ECU + slip-on exhaust + k&n air filter(got it just coz it's easy to clean and maintain as my dad's cars also run on k&n filters) . What I am finding is that my engine is running lean and I am on the normal map from Powertronic since I purchased it for my stock bike and all the mods came in afterwards , not able to visit a dino tune but can you suggest me which map to run on ? I have searched all over the net, was not able get to any information what so ever : (

[@ricardopinto1765]

Just a question about this mini cat delete: does that change improve the bike for better air flow i guess, but in terms of power? Could that change could make the bike runs lean??? Do you need a piggybag? Thanks😅

[@MotoMedicine904]

It’s highly recommended that you run a piggyback ECU or some form of ECU modification that can add more fuel to the mixture when deleting the catalytic converter. This is especially important when running a modified air system in combination with the cat delete

[@ricardopinto1765]

@@MotoMedicine904 on my case I was just looking for the cat delete ONLY still need a piggybag?

[@MotoMedicine904]

@@ricardopinto1765 you “might” be able to get away with it if everything else is stock but it’s no guarantee. Bikes already run on the leaner side for emissions so it’s a gamble. The factory lean condition is also the reason these bikes don’t like to do fine low speed throttling.

[@Duke-SBR]

Will this pipe fit the 2023 duke 390????

[@MotoMedicine904]

You’ll have to order one for they year group as the exhaust clamp style changed after 2021 I believe it is

[@Duke-SBR]

@@MotoMedicine904 i cant find anything for the 2023. Very limited

[@MotoMedicine904]

Anything 2021 or newer will fit the 2023

[@Duke-SBR]

@@MotoMedicine904 thank you mike!

[@AJ-hg2vj]

1.do i need an ecu tuning if i have the standard exhaust on? 2. otherwise does the engine have less power? 3.and where would i get the ecu from? I know my englisch is Not the best but i think you know what i mean

[@MotoMedicine904]

ECU tuning is still highly advisable when deleting the catalytic converter.

[@AJ-hg2vj]

@@MotoMedicine904 okay can i do this by myself or do I have to go to a workshop?

[@MotoMedicine904]

That depends on your skill level. I have a video explaining how to install a Powertronic ECU.

[@AJ-hg2vj]

@@MotoMedicine904 okay Thank you

[@Magewars12]

I do same thing on my Svartpilen 401 with IxRace M9. Now, sound is a lot more louder for me but sound really nice. I hope police will not punish me because i live in France !

[@MotoMedicine904]

Hopefully not! Police haven't bothered me so far with mine and there is a noise ordinance in California

[@phuoctho_]

Hi dude, for your ktm duke 390, have you ever seen the white smoke during cold start? I faced with the issue, I saw the white smoke during start up the engine in the morning. The issue only happens in the morning only

[@MotoMedicine904]

Only on a cold day. You'll get some light white smoke due to water burning off inside the exhaust system. Keep an eye on your coolant and oil for signs of mixing. If all looks good, I wouldn't worry too much.

[@jamesjay1987]

cat delete + sc project exhaust same here. some white smoke on cold start.

[@เเจ็คดอสั้น-ภ9ต]

Hi if i do that do i have to tune the ecu?

[@MotoMedicine904]

Yes. Absolutely must run a tune for a cat delete.

[@lifelink3297]

Tight bro I literally just ordered the GP slip on exhaust and the mini cat delete for my RC 390 from comp werkes just waiting on delivery

[@MotoMedicine904]

Good choice. Mini Cat delete is the way to go. The full delete including the pre-silenecer is way too loud.

[@kal1385]

Hii....1).did removing catalytic converter increase your bike performance?!? 2) after mini cat delete will sound loud on stock silencer?? 3) after mini cat delete can we run bike on stock ecu without tuning??? Plz reply. ....

[@MotoMedicine904]

1. Yes there was some increase in response in power. Especially in torque. 2. It will gain some sound but on a stock silencer it will not be that loud. 3. It is recommended you run an aftermarket ECU when deleting the cat

[@renzomf87]

This is exactly what i was looking for my Husqvarna 401 Svartpilen (same insides :P) Would you do this mod without the ECU mod?

[@MotoMedicine904]

It's not preferable but you could get away with it for a little while. What I wouldn't do for sure is all the bolt on mods without an ECU to help add fuel.

[@tieskejansen]

So are you doing a remap after installing this?

[@MotoMedicine904]

I already have the Powertronic ECU. The maps they send out with them are already friendly with the mods I have. I am having the bike custom dyno tuned soon though.

[@tieskejansen]

@@MotoMedicine904 Thanks for your quick answer. What do you think it will cost to remap and how much time they need to have to do it?

[@riccardobrancato8864]

Hi. Love the channel. If I put a competition werks mini cat delete, pre silencer delete pipe and slip on. Would I need a ecu?

[@MotoMedicine904]

It would be highly recommended

[@riccardobrancato8864]

MotoMedicine Thanks. I was thinking on a rapid easy bike ECU. Would that be ok? Or should I go with something different. Any thoughts?

[@MotoMedicine904]

The Rapid Bike Easy only compensate a little bit of fuel not much. Its easier to just bite the bullet now and get a proper ECU.

[@riccardobrancato8864]

MotoMedicine Thank you so much. Your bike looks good. Yea I was thinking the same thing. Just wanted a second opinion lol. A buddy on mine has the same bike and he wants to put a K&N air filter. Does he need anything for the bike to run properly? I think it should be fine and the bike would run ok. Thoughts?

[@MotoMedicine904]

1 simple mod.like that may be ok but anything beyond that really deserves a fuel controller

[@gekolizzard]

You can get pretty much the same sound just by drilling out the baffle.

[@MotoMedicine904]

Deleting the cat is not about sound, it’s more for freeing up exhaust flow for more power.

[@bfarm44]

Lose the pre silencer too. Wear clean gloves

[@MotoMedicine904]

I lost the whole bike lmao
