@@danitasconesrios1678 No electronic failures if you also remove the cat, but it is recommended that you upgrade the ECU, either with Upmap or Aprilia race ecu.

@@knekt75 Thanks, I am in doubt since the mivv exhaust and most are direct lines removing the catalyst and obviously the owners do not reprogram for an exhaust I will try to do the same as you by removing the cat

Com'è uscito?

@@alesanto8922 perfetto. Magari ora che me lo chiedi ci faccio un video e lo pubblico.

@@MazzolaRiccardohai avuto problemi per quanto riguarda l’erogazione? Da quanto ho capito il catalizzatore rimane quindi non dovrebbe essere necessario rimappare

Hi.. Sorry, I have no idea how the Motobox configurations look internally, and I never installed a tune. My plan was to keep the modification modest so that I did'nt have to upgrade the ECU...

Thanks for your input! I also think the result was ok, or maybe a bit more than ok. Soundwise, I was hoping for deeper rumble, but instead settled for the sporty sound. Regarding de-catting the system, I'm still thinking that _maybe_ I should have gone "all in" and just deleted that damn thing. But still, I'm happy with the current result... And those header nuts, they are a bitch for sure :)

If you de-cat it you need a Race Mapping or you get some real Problems with the motor 😵‍💫😵‍💫

I don't think so. This modification is quite modest and the cat is still in there.

Sorry, I'm not aware of any sound norms. But in the current state it's over 100 db at 6000 rpm, which could be too much I guess. However, I had zero complaints and personally I don't think it's too loud. There are so many louder bikes out there...

@knekt75 that's true Then thank you for your presentation ! I'll try it on mine and if it's bad there some stock exhaust on Leboncoin and others

@@Wolfdgt Yeah, there are plenty of exhausts on the used market. Go for it.. :)

​@knekt75 had you taken the radiator out to pull out the exhaust ?

​@@WolfdgtNo, I only removed the 4 bolts and kept the radiator hanging in the coolant hoses. This will give enough clearance to remove the header nuts 👍

Svetsningen utfördes av en mekanisk firma i Stockholm. Firman gör flera jobb åt mig i tjänsten och gjorde svetsningen som en vänlig gest. Det var en engångsföreteelse och de utför egentligen inte sådana här jobb på daglig basis..

Grymt tips, blir till o göra detta i helgen :)

Maybe some loss of back pressure in the system, but there still is a cat and minor pipes in there so its not a totally free flowing system. I havent noticed any loss of power...

No, in the current setup, it's not too loud.

@@knekt75 will try to remove the catalytic then and lyk

​@@STRAZZcool.. keep in mind that if you remove the cat you most likely need an ecu tune. Good luck 👍

Hey. Im currently not in the same place where my bike is. (I have a 2023 tuono 660) I did the same as in the video and also drilled out the catalytic converter. (I kept the so called pipe that held all the metal so it doesn't go through any other chamber). In a week when i get back i could send you an audio if you'd like to compare them. I also have photos of the process if you need them.

@@phylax8hi, yes absolutely do you have instagram ?

And it's relative simple and especially cheap modification. I paid about 100€ for the welding and that's it..

idk how to say it proper but i am scared like u need to remap the aftermarket once maybe also here

Genius way to fuck the bike... just read for 5mins online

Thanks! Yeah, a bit more growl for sure, but I wouldn't mind a more deeper growl. It's winter in Sweden, but I might post a flyby when the weather has improved.

👍🏻

Pls do it🙏🙏​@@knekt75

No, i'm not and no plans of updating the ecu. The purpose of this mod was only sound. If there are any gains in hp its just a bonus.

Yes, the cat is still in there. The exhaust is basically made in three different chambers. When removing these pipes and blocking the holes, the exhaust only goes through one chamber (instead of three chambers).

@knekt75 what those holes represent? I'm a bit confused. And by the way, how thick the metal blocker should be in order not to get melted completely when welding.

@@mahanghorbani523 This video wasn't really meant to be a tutorial, but here's a better overview... ua-cam.com/video/LJiDny7yX44/v-deo.html I think the metal blocks were only 1 mm in thickness. Any good welder can do this.

​@knekt75 ah that answer why only 3 holes is blocked. But could you say what thsoe 2 pipe and that one hole represents? Thanks a lot in advance

@@mahanghorbani523 they are only access for the exhaust gases between the three chambers in the muffler.
