I have completed testing and tuning with the Leo Vince decat pipe on the 2022 Mt10 . This decat pipe works with the stock canister or any aftermarket slip on canister designed to work with the stock mid pipe.
It has a nice finish on it and should hold up well. It has a small resonator to reduce the noise output some. I found the noise level with the stock canister to be about perfect. It was not too loud and had a really nice deep tone to it. Anyone that has ridden an uncorked CP4 knows the addictiveness of the sound it makes, especially if you like Moto GP. My sound DB meter measure 75 DB at idle and 125 during the dyno runs. Measured from directly behind the bike at about 30 feet.
The o2 bungs only accept narrow band o2 sensors so I needed to use an adaptor for the wideband when tuning
Install took me about 45 minutes from start to finish. It was a very straight forward install with nothing really tricky. On the 22 and up models the exup solenoid and o2 sensors need to remain plugged into the main harness for cruise control to work. A bit of a bummer but not a huge deal. The fit on the 22 was fine after removing the flange and gasket off of the stock cat pipe and putting it on the Leo Decat
My highly calibrated bathroom scale weighed the stock catalyst portion at 15.8 lbs with the Leo Vince decat weighing in at 3.5 lbs with all the hardware for a loss of around 12.3 lbs.
First dyno run is stock bike (red) vs Decat pipe installed with no tunning (blue): I left the air fuel curve viewable. There is a small gain at the top but losses at the bottom of the range. You can see in the air fuel curve it is very lean. It was actually above 18.0:1 at one point!!! I do not normally push this narrative, but I would not recommend running a decat pipe on this bike without a tune. The bike also ran very poorly when riding it with flash spots and bad throttle response abound

Next lets look at it with the stock ecu vs my tune. I still left the air fuel visible. Its a bit tricky to see as it follows my reference line . Now we are looking at some great gains. The throttle response from closed throttle especially in mode 2 and 3 is almost seamless! The connections between your right wrist and the bike is awesome. Combined with the exhaust/intake sound it really makes for an incredible riding experience. The Mt10 is not known for fuel efficiency but with my tuning methods the bikes usually stay pretty efficient. I did a 100 mile moderately aggressive loop with the flash and am happy to report I got almost 40 miles/gallon. Red curve is the stock ecu with the decat pipe , blue is with my flash and decat pipe
Now lets compare the stock bike (red) vs decat pipe and my flash (blue). Notice how smooth and flat the torque curve is now!! It went from embarrassingly lumpy to one to be proud of.
