I had a complete exhaust 2.5" pipes with highflow cat and flowmaster for under $275. The cat was $65 and the local shop welded it all high and tight.

The only pain was that the "direct fit" cat had a slightly larger diameter outlet than my muffler would recieve so I used a muffler pipe expander and opened it up. Buttuned it all back together and couldnt be happier with results. Just by replacing my cat I got back my 5th gear and have great fuel economy even with my 4banger and 33's. As I said I thought I had the factory cat but when I brought it to the scarp yard the guy showed me that this thing was a aftermarket which explains why it was welded on. O well he still gave me five bucks better than zero. good luck.
do you have tha part number for that stabilizer stud..? thanks

mine was both, it had a flange that slide inside of the other one, and then clamps overtop of the joint....we had to use a propane torch to warm em up and expand the rust and corrosion before we were able to pull them apart!!
