[Mo2002]

I chose to go with the non comp to save myself some $$. I don't regret it. I have the upgraded wheels, leather upgrade and I purchased the black grill, fender trim, tips and x5m emblem separately and installed them. Looks identical to a x5 comp minus the black Rear diffuser that the comp has.
The suspension is just as hard in the non comp than it is the comp. I have the secondary cat delete and it sounds great in my opinion. I don't think there's much of a difference in exhaust sound between the comp and non comp.
I also.have the MSS suspension to take care of the hard stock suspension and awful ride height.
