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...
