100% normal for most early cars. I think LCI ones have modified exhaust valve assemblies.

Dealer will change out the exhaust it if it really bugs you as it's a known fault.

You could remove the internal spring in each valve housing and stretch it out a bit and then re-fit. Worked for me but it is a PITA to re-fit the spring into the valve assembly.

Mad.
