2000 Subaru Outback Emission Control Parts

The cat I purchased for my Subaru Outback functioned as it should. I passed the smog inspection. It did fit well enough. There were some issues with the heat shields from the stock unit not fitting over the large tabs of excess metal shown in the photo. There did however, appear to be some integral shields on the rear cat and a "double wall" pipe section on the unit that I suppose suffice. I was able to fit the main shields on to the first cat so it seems fine. I recommend that the entire Y-pipe and cat assembly be dropped together and swapped out on the bench so you would need new gaskets for the head and tailpipe connections. Much easier to work on the sensors that way and well worth the few extra bucks.
