[BMWI6]

Hi guys, I just traded in my 335 for a z4 m roadster that I will be getting next week and I only have one worry. For me the exhaust sound is very important and I absolutely love the sound of the e46 m3. However a friend of mine told me that the z4m does not sound even close to as loud as the m3 because of its more restricted exhaust. I have not heard the z4m, is this true? Is the car loud and raspy at WOT? I hope so, thanks
