    Help identifying something on y-pipe/cat

    The welding worked out well. They didn't even warp the pipe. Everything fit without a lot of struggle. I can't say everything downstream of the O2 sensor is perfectly sealed because some of the flanges couldn't be cleaned up perfectly. I can't drive it until I get the interior put back in...

    Well that welding job cost more than I thought. $250 and that included putting on a new Slee O2 bung, the y crack, and 3-4 flanges that also had welds that failed. They also pressure tested it. This was going with a more reputable shop that has been in business for 20 years. I tried to...

    Thanks. Yeah, that gasket is leaking too so I have to pull them.

    Good advice, thanks. After looking carefully, there's no reason to replace this thing. The bung is leaking too and it appears to be more weld than steel. I didn't realize Slee sold a replacement and I have that on order. That will give me some time to figure out what over-sized stud size...

    Only the joint of the Y is leaking from what I can tell. Maybe a good welder can grind that part off and patch it up. The unknown is if anything else is leaking too. I used a leaf blower and soapy water to test. I could have missed something. Would be nice if it could be pressure tested...

    Anyone have experience having something welded after the original weld failed? I cleaned things up and it seems worse than I thought but I really don't have experience with exhaust repair to know for sure. I see several repairs on the y-pipe. Time to suck it up and replace?

    Help identifying something on y-pipe/cat

    That's great to hear. I plan to clean it up really good and then try to find a good muffler shop. I was bracing for having to spend the money on the Magnaflow but there's been a lot of mixed information about one version not fitting correctly, some change after they acquired Bosal, and few...

    Help identifying something on y-pipe/cat

    That's a big relief. Didn't want to replace this. Other than the crack, I need to deal with some of the studs that were drilled out too big on the manifold. One of them had a bolt that was too small for the oversized hole and wasn't sealing anything. Bolt spun off by hand. Hopefully I can...

    Maybe that’s why the heat shield is cemented to the cats. To keep it from rattling.

    Thanks. I had no idea there was ever a heat shield there.

    Help identifying something on y-pipe/cat

    Yeah, it seems like a metal tag maybe that was welded on for some reason. Not sure of the O2 bung condition yet. I have a crack in the crotch of the y-pipe and need to figure out if that paste around the edge of the cat is really covering a very long crack. The previous owner has this stuff...

    Help identifying something on y-pipe/cat

    Does anyone with an OEM y-pipe/cat recognize what this is metal piece is (or was) on the pipe? It's directly opposite the O2 sensor. I was about to use the wire wheel on this to clean up spots for welding. I don't know if I should grind this off or what. Looks like two spot welds holding...
