I used to run avgas for track work in my previous AW11 4agze Sprinter. No cat but with O2 sensor, never had a problem with the O2 sensor, but I seem to remember that there is about a 100 hour limit and then the sensor will die.
Avgas also tends to destroy platinum plugs as well.
I noticed a slight improvement in low rev response and mid range torque with avgas.
Now that 98 RON ULP is available there's really no point in running avgas, if you want more octane add some octane booster like 104+ to 98 RON ULP and that should be more than you ever need.
