Did you feel any lost in low end torque ?
I did 40 km back from my dealer and was easy ride. Did not feel any difference.
I think it's so little that the most of us don't feel any loss of improvement. For me 200 bhp or 201 or 199 was not the point to buy the Yoshi.
I also don't care too much about peak horsepower but low end and mid range torque is where we spend most of our time.
Continue to take attention to that and tell me.

you are not going to loose any low end torque with installing a slip on with this bike

Okay, on my old bike(VFR 800 F 2017). With a slip on a lot of torque down. Despite the VTEC.
I hope the power valve help to keep that velocity at low rpm.
I want to take a MTC exhaust. I don't know if the diameter of the Yoshi is smaller than the MTC.

I don't think you will lose torque, however, running without slip on or a very very short one would (MIGHT) cause damage to valves in long term.

No way with the cat in the header and muffler box. Plenty of crap there

agree, the bike is tuned so rich from the factory and there is still plenty of resistance to flow with the pre cat and cat that you could completely remove the canister and not hurt anything including low end power

At low throttle position and WOT
On your dyno results, the AFR WOT at 3k-4k is lean too
