E53 exhaust and kits
 

Hi, I just bought E53 X5 3.0d 2006.
I was wondering If someone have tried to fit the Aero kit and the 4.6/4.8 wider arches together?
And about eissenmann exhaust I saw that they have sport and race for E70 and for the E53 I think they have two types but it's seems like the only different between them is the tips, is that right?

If there is a good thread on current exhaust available - or if anyone jumps on this thread - please help out Mintho AND me. Our 4.8is is at the body shop for a light rear-ending.

We have the option to swap stock exhaust for better - but need to act quickly.
Any help?
Appreciated. Thanks
