Hi all just fitted a new nearside cat on my 2.6 v6 quattro the cat came in two parts the part with cat and bit that connects to manifold then there's the piece if tube that connects from cat to back of exhaust pipe.the piece of pipe at the back is still blowing from the joins if that makes sense and no matter how tight I tighten them it still blows.any ideas guys.thanks in advance for any replies
