Why does my Audi 80 produce a loud noise when I accelerate?

I have a 2001 Audi 80 sedan and recently I have noticed that when I press down on the accelerator, there is a loud noise that comes from the engine. It's not a rattling noise, more of a growling noise. What could be causing this issue?

It sounds like your exhaust system may be loose or damaged. This can cause a loud noise when the engine is under load. It's best to have it checked by a mechanic as soon as possible to avoid any further damage.
