Assume you have a sports exhaust which sounds awesome but suddenly starts to quiter or less awesome.
there are no air intake, engine or exhaust leak problems.
Could any other factors cause it to become quieter? For example you repeatedly hit bumps on the road can the intervals of a sports exhaust get damaged to the point it will cause a change in sound causing it to sound quieter/more like a normal exhaust. If yes which subsection of the exhaust might this happen to/need replacing?
