Cat and exhaust

[05OutbackXT]

OK,dealing with an 05 Outback XT, that needs a new downpipe cat, looking for suggestions on the right aftermarket cat, as well as the BEST aftermarket Stainless cat back exhaust with stainless 2nd cat, and mufflers. I do not have a local Subie club to ask. Are there high quality (thick walled stainless, attention to detail manufacturing, etc.) aftermarket suppliers out there???
