So I'm changing my head gasket because it is really blown and when taking the downpipe off to get the turbo off, by the way the downpipe was a bitch to take off it looks like my engine has never been taken apart or worked on which in some cases can be good... Anyways we finally got the dp off and there was a cat welded on not a factory job from what I can tell. The weld was not very good but it looks like the wrong cat is on there, like they took the cat off exhaust pipe and welded it in. I'm not sure if it is the original cat or not. Maybe that is why my hks super dragger is so quiet, more quiet than stock haha! My dp is on the way I bought the bic divorced dp! My friend will post a picture up of the dp with that welded cat on there and someone tell me if that is stock or not..thanks!
