The R and gti have it to make them sound like v8s. Loads of manufacturers doing it now. The first thing I'm doing will be to turn the soundaktor off or down.
Were not talking about the soundaktor (which is standard on all GTI/D & R) - Its the S&S pack (only on GTD) witch deletes the rear silencer and adds an integrated loud speaker into the exhaust pipe, thus creating a pretend exhaust note from the diesel engine.
This is correct, however, as pointed out above all manufacturers are doing this to meet the rules on noise emissions. Even Aston Martin and the like are at it. They realise people want cars to sound a particular way and the legislation means that it is no longer possible to do this mechanically (though some high end cars use exhaust flaps to keep the sound down below certain rev/throttle combinations).
Yes, correct, but the GTI and R don't have a speaker in the exhaust, only in the cabin.
Bottom line is the S&S pack makes the GTD sound like something it isn't. It's
pretending to be a larger more powerful petrol engine car.
