Two Questions;
1) The BMW issued exhaust mod...has anyone done it?? or heard it?? $695.00 installed at my dealership...should I do it? More importantly will it sound good? I have the 2.5L 6sp
2) Nav is the only thing that didn't come with the X3....I was thinking about an after market Alpine...or maybe the issued BMW one...anyone do any of these aftermarket mods...does it look good? is it hard to install? would I loose the steering wheel controls if I put in an aftermarket Nav / Stereo system?
post pics if u have any!!! =) thanks!!!
