Hello, I have to change the exhaust systems on my daughter’s 500s. One problem is that the car is about 300km away. (Do I need special tools? Is there something where I have to pay particular attention to it?) I was told that I have to solve the rear axle to change the exhaust system(or have to let off) Next statement, for this car there is only one connected system. I find two and three-part systems for each online spare parts dealer. Has someone changed only the endtoprf? The exhaust on our 500s is actually one-piece and is torn off exactly before the endtoprf. My idea was to renew only the endtoprf. Does anyone have experience there? In advance already thank you for answers and suggestions. Nice greetings. Helmut. Oh yes our 500s is BJ.09-2013, 1.2l and 69PS
