I'm in Watertown, NY - north of Syracuse by an hour or so. I play a lot in Central NY and Western Massachusetts on weekends, so driving the exhaust around is not a big deal. I am 45 minutes from Gananoque ON and heading up to Kingston ON for dinner is always a treat.

I don't have a sound byte, sorry. It wouldn't carry the chest-resonating frequencies very well anyway... Nothing captures a stereo exhaust worse than a mono microphone with crappy encoding on a PC. =( Think of a Chevy pickup with a 350, twin pipes, and Flowmaster 60s (the more subtle models), not 40s (common whiplash models).

The pipes should hook up with no problem to your 2004 X5. If you can look at your undercarriage and compare with the photo above, you've got a good chance. Make sure you have flanges/bolts at the back of your resonator and not a welded pipe. Not many shops can weld stainless well (TIG takes serious skill) so I'd rather have pros mold the parts and have the locals bolt them on. Apparently BMW thought so too.

Re: motor compatibility: there may have been some changes in the supertuned/stroker motors (4.6L?) that include exhaust relocation... and my earlier post about hookup pipes only applies to diesels (likely different resonator for emissions, if any?). The gas 3.0L looks like they don't need the hookup pipes. Again, double check other sources to make sure since I don't own an X5 (or a dealership of 'em) to confirm.
