No, I don't think is rusted through.
The leak goes away with a new gasket everytime they put a new one in.
But it comes back the same day after driving around 2 to three hours. Could it be the rtv? Should I let it sit longer and then start driving?
I have never had this problem with any other exhaust but who knows? The temps are so extreme with this cars that it may be something odd like that.
They are using the red rtv. Isn't there one that is for greater temps?
But again it could be the gasket material. I have not seen the gasket they use yet. This is the same gasket material used in piston engines right?
I mean Meineike should know what to use. Yes this is a DIY job but the first time I took it in it had exhaust leaks everywhere and they welded the entire system making it pretty tight and very nice.
