    Midpipe to Y pipe not connected

    So I had my catalytic converter replaced because it was bad (CEL, idle was a bit weird)... Now with the new cat, I hear this exhaust tick/leak towards the back of the car. Got under and checked and the mid pipe isn't even connected to the y pipe. it's just kinda sitting in there.

    Is that usually welded or is there a gasket that should be there? If so, where would it have went? deteriorated and fell out possibly?

    I quickly did a search and came across a forum that said it was a gasket -- Welker 31556 to be exact. Please confirm.

    This is SPT exhaust btw. I'm not sure if it's from the factory or aftermarket... I am the second owner of the car. I believe it's aftermarket. It isn't the double tail-pipes, it's the single tail-pipe mufflers.

    it's a 2010 Subaru WRX Sedan by the way... that might be important to know...

    Just get a new gasket up in there and bolt it up...not really a big deal.
