Toyota has some previous in this respect!
Mac will tell you the same no doubt - the closed Toyota sports cars of 10 years or so ago did that. Accelerating out of Arnage corner at Le Mans you would see, at each gear change, the twin flashes from the exhausts and a split second later - CRACK! - and you thought a sniper rifle had gone off right next to you!
Then Mr Brundle's car crawled round and expired right under our noses... After that there was only one set of cracking noises when the remaining Toyota went past!
