I am not sure but I think Sweden had strict noise restrictions.
It is only to late to take it off if the motor has already suffered heat damage.
It is a generally accepted to take the diaper off the 89-94 Carrera to.
Especially if the new owner drives it hard or is running it in a hotter climate. I would not do a DE with that on.
Besides it should help better that beautiful air cooled symphony we all love.
Just my two cents worth and not worth a penny more.
