So what you are saying is everyone with SS pack are trying to, or pretending to, make their CR 2.0 TDI 184 sound like a 2.5litre 5 pot 400 bhp TTRS/RS3?
Wow, you do read what you want to read don't you? The devices are programmable, they're used on mercs, audi's , vw's and I don't doubt every other German car maker. Diesel, Petrol, whatever, the manufacturer can choose what the sound is like. There's even a Kufatec box for these cars that lets you select a variety of different sounds.
Me personally, I don't ever think a diesel is going to sound like a 2.5 petrol, nor would I want to try. Making a diesel sound better? Very much so. You don't seem to have experienced the S&S pack for yourself but I will say that it sounds nothing like a V8/V6/Straight 6 or any other "nice" sounding "proper" engines making their natural noise, it does make a normally boring engine sound a bit nicer. But, as I said earlier, even those putting in "proper" engines are using these devices to "augment the audio track" of the engine.
You don't have to like it, you don't have to buy one (though the day is approaching where all cars will be "augmented"), not sure why you feel the need to berate the choices of others?
Good look buying in the future,, they're all at it.....
