Well, There was a slight **** up on my part. Not realizing the car had a resonator, and due to the location of the CAT. It wasn't until the car was in the air I realized what I thought was the CAT, was actually the resonator. I've never been under the car before and the CAT was much smaller then I've ever seen a CAT to be quite honest.
The Resonator had a pinhole exhaust leak causing a horrible sound. We cut it out, replaced it with a straight pipe, and the problem is solved.
I apologize for the mix up on parts.
For anybody searching - The exhaust pip is 2.25 OD from CAT to resonator, and 2" ID IMMEDIATELY following the resonator (IE Before the bends) We cut the exhaust support free of the the weld with a cutoff wheel, and re welded it to the straight pipe. This was less than $40 worth of pipe/fittings/clamps.
