I noticed a loud rattling sound that briefly appeared two months ago but only lasted for about 3 days. The sound started back up a couple days ago and I located the source of the noise at the passenger side catalytic converter. I have S&S headers which came with a Y-pipe and two cats.
When I removed the cat today I found that one of the two honeycomb elements inside the cat had fractured and was in two big pieces and one small one. The biggest piece was wedged very firmly against the exit side opening. My exhaust has smelled a little rich for a while so I'm not sure when this happened or even how it happened. It's also odd in that the CEL has never come on.
Here's the album with three pictures of the cat.
I called S&S but got their recording so I can't ask about a possible warranty from them. I'm willing to bet that there isn't any. I'm certain that I've found a replacement made by Car Sound which is marketed under the Magnaflow brand.
The cat is stamped with 94100 and its dimensions are identical to Magnaflow's model 94116 which also has the air tube. I'm going to buy the 94106 which doesn't have the air tube since it's not used buy our trucks. It goes fro $72 on some mail order web sites and $55 on ebay. All with free shipping.
I'll have to get the three bolt flanges welded on in addition to an extension on one side. Should I have this done and then installed at a muffler shop or should I just give them both cats and have them make the new one look like the old one?

PS: While underneath my truck I noticed that my headers and y-pipe are starting to rust. I'm glad I kept the stock exhaust as I might be reinstalling it in the future.
