Exhaust Sound mods

[Kyle auty]

Hi All
I have a Z3 3.0i and a friend of mine has a Z4 3.0i both M54 engines. On the Z4 we removed the foam from the Sound Conducting Pipe, this makes such a difference in the cab and also out side the car especially with the roof down. Is there any similar mods to enhance the Exhaust tone that can be done to the Z3??? She is completely original and I want to keep her that way, hence I really like the Z4 mod. Any advice would really appreciated.
Thanks
Kyle

I tried the noise mod on my Z4 and found it irritating so I put it back. I settled for a nice induction roar instead.
