Howdy,

Sold my 4.4i+spt 2 1/2 years ago and have missed it ever since. I'm picking up my new X5 4.4i+spt this weekend but after driving an M3 for the past couple years there's a few things on the X5 that will have to go.

From a performance standpoint at the top of my list is the exhaust and the cold air intake. To be specific, I'm not actually looking for the product that delivers the biggest performance boost but rather the exhaust that closest resembles the sound of a cigarette boat. Likewise looking for a cold air intake that screams.

I've seen some 4.4i's with Dinan stickers on them that growled and I'm curious if that's indicative of the Dinan exhaust or not?

Any recommendations would be greatly appreciated.

Thanks,
Josh
