hello boys, I would like to know how it looks with the (sport) exhaust systems of the numerous manufacturers (bastuck (brutal loud?), sebring, etc) – is it possible to achieve a noticeable performance plus (so in the ‘normal’ area) without the car noises like a jet nozzle? I don’t have a great desire to stand on a level with the noses that are always on mcdonalds or fuel station parking places and bother other people with unnecessarily loud noise. so mark ‘mint green opel corsa from mutti with thick flaps and oven tube’, you know ) in short: are achieved performance and extra sound up to a certain point proportional or is it also a bit quieter or more discreet, but still with additional performance? (would be about a bora, but I post it here) would be nice if you could recommend a few manufacturers and had approximate prices available. many thanks to kumquat
