Hello, I’m about to rebuild, I want to make sure that my engine is iO, so some tips would be very helpful 😉 How come that my car sounds like when it had a brutal sports exhaust when it was speeding up? I have something like a strong turbo hole (it’s about a gasoline engine!) up to speeds of over 2800-3000 rpm. If I get the pedal all the way in, it gets very loud, but hardly accelerates – it can only be slowly “accelerated” with a feeling My exhaust is not the latest, but is not leaking, just ask, since I have memory, if I will still have the problem after swapping the entire exhaust system (costs almost as much as a replacement engine).Data: Audi 80 MKB: DS Carburettor: Pierburg 2e2 BJ: 1985
