Took the car out for it's first long trip....quick run from Chicago to Milwaukee and back tonight. Car ran great after the timing case rebuild! Unfortunately lil car let me know it wasn't going to put up with the noisy exhaust anymore.
Of course it couldnt be simple....it seems as though the exhaust pipe has rusted clean through and broke about 5-6" to the engine side of the cat...this seems to be a single piece consisting of the cat, some exhaust pipe and a flange that bolts to the header.

I have no reason to think that the cat is not functioning. Replacing the unit as a whole seems like a huge waste of money. It looks to be a fairly clean break though. I know there are sleeves that I should be able to buy a bit larger than the OD of the pipe, and was thinking of sliding that over the break and clamping it down. Is this a workable solution? What sort of clamps should I use? Is there any sort of sealant I should be using in addition?
As much as I like to DIY, I have had enough cuddle time with lil car....is this something a muffler shop would be able to patch up for me? I really don't want to take it in and have them give me a song and dance and then ask for 250 to slide a piece of pipe over the break and clamp it in. On the other hand I would like the fix to last for a couple of years if possible. I have no experience with exhaust work so any advice would be terrific!
As an aside, doing WOT starts from stoplights sound about as good as it gets :p

I would just get a section welded on at a muffler shop. Stay away from chain places if you or someone you know have never dealt with them. A lot of them work off volume and $$ for their high overhead and franchise costs. Midas raped me last time at my time of need.
Let me know you location and I could possibly recommend you a couple places.

Id get a piece welded in, but it looks to be rust from one end to the other.....is this possible still?

NM! I went under the car and it looks as though the steel is still plenty good, just that the weld had failed at the cat....off to call some shops :D

Good news. I thought our exhausts were stainless steel but wasn't sure if it was all the parts or not.
