OMG more dumb dumb shit found tonight.
Wayne provided a really nice set of 2 1/2" cat delete pipes he wanted put on. (they were on the car at a previous time with the old owner)
the mid pipes were also replaced (a great job btw) with 2 1/2" pipes to the Flowmaster mufflers.
Im thinking the factory cats will be bolted on with a flange, since I peered under the car and saw.....a flange!
Not. The cat pipe was welded TO THE flange. So I cut the pipe at the weld and spent a stupid amount of time grinding it down flat.
Then I notice the dumbest thing ever.
The exhaust shop used the factory 2 1/4 flange on the mid-pipes. OMG

Sorry wayne, but I dont have the proper tools, nor an air compressor big enough to open up this hole.
On a side note, here is a pic of the transmission drain plugs i add to all cars I work on:
