This is turning into my chronicles of working on the car.
I got underneath and yes it does need to have new exhaust bolts and clamps. When I went to take out the MAF on of the screw heads severed and it too an act of congress to get it out. As much as I hate to 'jerry-rig' something, I had no choice and had to completely change the screws on the MAF. One side of the plastic was completely gone so I had to use a long screw to reach down into the lower plastic. I was thinking of doing a new intake so I wasn't too worried about the look as long as it was functional.
Once I got it all together (3 hours later) it was clean and solid. Took it for a drive and no CEL yet and runs well. After I put the rear speakers in then next will be the exhaust.
