Just drove it around a little. It even rattles at idle but gets very loud in every gear around 2500 rpm. It sounds like a metal on metal grinding noise and seems to be coming from the passenger side. I can deal with the hissing and whistle noise I just can't figure out WTF it's hitting as it seems to have a good inch of clearance above the cross member.

I really don't mind the hissing and whistling sounds. I'll either get used to it or replace the test pipes with stock cats. I just need to figure out what the pipes are hitting, and why it appears to be coming from the passenger side and is loudest between 2500 and 3000, and now under load AND decel

EDIT: Soundclip
Memo.m4a

This is second gear accel up to about 3500 and back down. Note the loud rattling on decel. Helps to turn speakers up.
