2024 Yamaha MT09 Kelpi full exhaust testing/tuning: Flashed by Vcyclenut

[@thomasmichaelhopper2141]

Hi, It's great to see you tested those two db killers - 6:51 onwards. Very interesting results too - thanks! I've tried both and didn't like the sound or feel of the pipe with big holes. I also tried cutting the shorter end of the perforated baffle off so it is open at the shorter end but still closed at the longer end - and found this much less restrictive but still offering a decent reduction in noise. I dunno if I can post a pic... anyway, thanks again for sharing this!

[@aussieboy424]

I've been waiting for this one. Cheers mate

[@vcyclenut]

Hope you enjoy it!

[@newballin]

Same same, now I can finally order the Kelpi 🥹

Nice work, good job

[@shlembot]

I love these! I have a gen 1 so these don't apply but I watch anyway :) Out of curiosity, what are the stock decibel numbers? Thanks!

[@vcyclenut]

I have the db readings in my stock bike tuning video for the stock bike www.vcyclenut.com/2024-mt09.html

[@shlembot]

@@vcyclenut I couldn't find stock db numbers on any of those videos, but I did find it on this one at 6:12 kzbin.info/www/bejne/j36Um6eBlLNri5I&ab_channel=vcyclenut 112 db for stock if anyone's interested. Thanks so much for documenting all this for us!

@@shlembot sorry about that. Thank you

I'm trying to decide between this exhaust, the Yoshi, and the Leo vince. Like the look of the Kelpi the best, Yoshi is the best sounding and LV is best for not too loud which I like. I ride home at night and dont want to wake the neighbors so leaning toward the LV, all things considered which one do you like the sound of the best?

[@vcyclenut]

Probably the Leo Vince

[@jleffler316]

How about the Austin Racing box delete GP1R?

[@mytmousemalibu]

Love the looks of that one, just wish it was a full system & titanium, not just a decat.

[@HassanIsDriving]

This full system is very nice, but I’m actually interested in the Austin racing GP one hour system even though I have to cut my headers. I personally like that better.

[@javedimran8991]

Hey I’m interested to understand the different torque and hp in different modes. Is that a comparison that u can do.

[@vcyclenut]

modes 1-3 are the same at full throttle what is different is the response curve at part throttle mode 1 is the most aggressive mode 2 less aggressive mode 3 less aggressive mode 4 left as stock

[@javedimran8991]

@@vcyclenut oh that makes allot more sense. So for mode 4 they just limit the max throttle. Nothing to do with torque curve. Thanks for clarifying

[@predalienftw]

do you change how the different modes operate with your tune, like how the throttle responds differently in street vs sport

[@vcyclenut]

You still have all the modes. Mode 1 is the most aggressive mode 4 the least

Hi, I have a question my 2022 Yamaha tracer GT with dominator full exhaust and K&N filter If you do, ECU flash O2 sensor have to stay or no ? For more cruise control to work please let me know. Thank you.

[@vcyclenut]

It has to stay plugged in but I’ll disable it in the flash 2 different things You can also install the o2 elimination plugs I sell to completely remove it and still have cc.

Yes. The toce is already ordered. I’m just waiting on it. The Mivv is also on the list

@@vcyclenut same price as yoshi right? Around 900 ish. The toce i was looking at was close to 1400 all black pipes from headers, which is ridiculous. I feel that Leo is hanging lower than all other exhaust and looks like tip barely has cleared swing arm

[@vcyclenut]

@@damacknificent151 yes I sell it for $930. Zero issues with dragging or clearance on the Leo. I’ve probably sold close to 100 of them for the 21-24 cp3’s www.vcyclenut.com/store/p226/2021_-_23_MT09%2F_22-24_Tracer%2FXSR900_Leo_Vince_Race_exhaust_system.html

Is this the shorty version or the flanker?

Flanker

[@rustcohle6248]

@@vcyclenut They look very similar, would this flash for the flanker work for the shorty as well?

@@rustcohle6248 yes. Just changing the canister type isn’t going to change performance or fueling needs

Dave how did you end up with that standard db killer? I don’t remember seeing it as an option when I was ordering

[@vcyclenut]

I contacted them and said I wanted whatever db killers they had.
