What you need to know

Motorcycles over 125cc are inspected at resale and after an accident (€57), including an emissions measurement and a noise assessment.
Noise limits depend on build year and engine size.
Secondary sources (not government) say a non-original exhaust needs an e-mark and must not be louder than the original.
Not confirmed by an official source.
