Performance parts for 4.6is?

[Doms X5 48is]

Hey guys, check my introduction thread over here (I am a new member here): http://www.xoutpost.com/bmw-sav-foru...ls-my-e53.html

My questiont today is: What type of performance enhancements can we do to my 4.6is 2002 X5? I just did a complete overhaul on the truck, new front axles, wheel bearings, brakes, tires, alignment, spark plugs, injectors, believe it or not there was nothing wrong with the car but every 50k miles I have my dealer do a complete check up and overhaul of the truck. I started noticing some front end noises when turning and at about 65 mph so I had BMW take a look and asked them to replace the wheel bearings and re-do whatever needed to be done in the front end.

The truck is running GREAT NOW!
My next step is to get it detailed friday but wanted to ask you guys is there any catback exhaust or cold air intake kits made for the 4.6is model x5? What other performance and cosmetic enhancements can we do for this model?

Thanks guys!
