My car has the solo cat back exhaust. I was already installer when I bought the g8 gt. My question is is there a gasket between the stock catalytic and the solo cat back tube?
Reason I am asking is that when I was under that today I noticed that a few pieces of rust came off. between the solo cat back flange and the flange of the catalytic.
Do the stock converter flanges rust out?
The stock cats do have a graphite exhaust doughnut to seal between the cat and the cat back. Yes they do break down after a while. Any exhaust shop can replace them it you ever develop an exhaust leak.
