the-missile:

aftermarket exhaust will first have to deal with new electrically actuated flap and that is challenge. the flaps are now linked with the filter for emission purpose...good luck trying to change that thing without starting to mess with the ECU of the car.

This and furthermore, any exhaust (aftermarket, OEM sport exhaust, whatever) cannot sound louder(!), not even a bit, then in the stock configuration. So basically the sound frequency will change (for example from a high pitch to a low growl) but not the loudness because it is prohibited.

In Germany, modding the exhaust system (for example removing the catalytic converters), is even considered tax evasion because the car slips into a different emissions class with a modded exhaust. Very serious thing.

The worst part is though: Police has rights now they didn't have before. They think your car is too loud? They impound it. On the spot. Not pretty. This is why, in my opinion, the market for aftermarket exhausts is basically dead.
