I think it was a Flowtech with 3" in and out. The exhaust shop just welded a ball flange on the back to mate up with the Y-pipe and at the front they just clamped it to the stock down pipe.
Back when I bought the converter (mine was shot) I had priced a factory replacement style from Midas and they wanted $350 for the converter and labor to install it. I just went to the local speed shop and ordered a high flow 3-way converter for around $160.
I hear some of the best converter's out there are made by Random technologies. I'm not currently running converters on my car now and thats really only due to the cost since I have dual pipes. It will cost me around $300 to put them on. But I do plan on it because it will help quiet the exhaust down some more.
