I can’t tell you figures but as I only do Knockhill and the occasional Euro track day I’ve never had any issues. I did put the supplied baffles in for the MOT and I was actually surprised how much of a difference they made. Again can’t give figures but the MOT tester didn’t even blink!
I have a complete set of US under-belly 959 exhaust system if anyone need it. It was pulled at about 2000 km. I also bough an another set for coring which I never did. Any reasonable price will do. Let me know. https://www.ducatiforum.co.uk/threads/959-panigale-us-version-exhaust-system.66639/#post-1673168
