I SUSTAINED SERIOUS BURNS TO MY CALF FROM MY THE EXHAUSTS ON MY 2014 BOXSTER S, AND MY 2017 CAYMAN, ON TWO OCCASIONS. BOTH CARS SUFFER FROM THE SAME DANGEROUS DESIGN DEFECT: AN EXCESSIVELY PROTRUDING CENTRAL EXHAUST PIPE. THE FIRST INJURY WAS SUSTAINED ON FEBRUARY 19, 2017, WHEN I LEANED AGAINST MY 2014 BOXSTER S, AND THE REAR OF MY CALF MADE DIRECT CONTACT WITH THE PROTRUDING EXHAUST PIPE. THE SECOND INJURY OCCURRED ON AUGUST 11, 2018, WHEN I PLACED A SUITCASE IN THE TRUNK OF MY 2017 718 CAYMAN, AND THE FRONT OF MY CALF TOUCHED THE EXHAUST. THE 718/BOXSTER S EXHAUSTS ARE UNREASONABLY DANGEROUS AS IT IS EXTREMELY EASY, EVEN WHEN BEING VERY CAREFUL, TO INADVERTENTLY MAKE CONTACT WITH THE HOT PIPES. ALTHOUGH THERE ARE PURPORTED 'WARNINGS' IN THE OWNERS' MANUALS, THEY ARE INSUFFICIENT AND FLAT-OUT ABSURD, AS THEY CANNOT BE ADHERED TO IF ONE USES THE TRUNK. I AM ASKING THE NHTSA TO INVESTIGATE THIS PATENTLY DANGEROUS DESIGN DEFECT.
