Why is my Audi 80's exhaust making a sputtering noise?

Recently, my Audi 80's exhaust has started to make a strange sputtering noise whenever I accelerate. It seems to be coming from the back of the car. What could be causing this and how can I fix it?

It is likely that your exhaust system has a leak or a loose connection. This can be easily fixed by tightening any loose connections or replacing any damaged parts.

One possible cause could be a clogged catalytic converter. This can be checked by a mechanic and replaced if necessary.

Another potential issue could be a faulty muffler. This can cause sputtering noises and needs to be replaced in order to resolve the problem.
