There is very little difference in noise levels between the 25/2.7 and the S models back box muffler - they all have to conform to EU/US specs.

If you want to get rid of the "cheap" sound of your aftermarket back box (muffler), install the original S muffler with cat delete (mid section) pipes. It will sound slightly louder around town and quite a bit louder above 3,500 rpm.
But I don't know how legal that would be in Finland....
2001 Boxster S (triple black). Sleeping easier with LN Engineering/Flat 6 IMS upgrade, low temp thermostat & underspeed pulley.
2001 MV Agusta F4.
