I drove it around the neighborhood last night. And today I've gone to work and home and to work and it's been fine. If anything changes I'll let you know.
There were two pieces of the wheel well that touched and that's right where the CAI was touching. So I cut little, curved pieces out until the plastic was no longer influenceing the pipe. I tightened the pipe down to the vibramount. I could shake it with my hand, but I don't hear any more metallic vibration.
