Hello guys. I drive an old Super Seven. When I bought the car, it was extremely loud because the engine was massively adjusted. The end pot was completely empty, so the sound had an extremely unpleasant pitch, which hurt the ears at medium/higher speeds. The car consists next to the seven-typical chassis of parts of different car models. There are no “original parts” for the car, the exhaust is a universal part. I can therefore within the db registration in the paper legally exchange. 3 years ago I used a significantly larger rear silencer, so that the car became much quieter (approx. 80db). But after a long search and testing I got the car car car / engine adjustment, the car has now become much quieter again and thus it lost its sporty characteristics. It has now subjectively less sound than a GTI. Entered are 88db. They do not necessarily have to be (the tube e My goal, however, is a more nuanced sound, especially when it comes to gas. Currently, a round pot is 420mm long and 150mm diameter installed. A size smaller would be 125mm diameter (length remains the same). It has a calculated 30% less volume. Does any of you have any idea what that does with the sound / how much db louder the slimmer pot is expected? Tips? Of course I don’t want to have to buy different end pots in the Trial & Error 5.
