Of course, the exhaust system is different too as the 4.8iS was a semi "M" model with more agressive note.

Ok you may be right but can I have that note please...

I guess no because the engine is completely different and the exhaust system for E53 might be of a different shape anyway.
So I guess you need to look up another aftermarket exhaust that would reseble truly lovely 4.8iS note.
