Personally, I wouldn’t want to pollute more than is necessary, though the cat delete would mean a performance boost (but is it necessary etc etc). There was an article or few from a decade ago stating that NOx and other emissions on average measured higher from motorbikes than cars. But I’d poo-poo that considering the successive scandals of fudged emissions tests by the car manufacturers.
All the same, the Euro 5 article is quite interesting.
