I need to replace my catalytic converter. The current one is held in place by U-bolts. Two U-bolts between the cat and the manifold exhaust pipe (looks like a patch). One holding the exhaust pipe to the exhaust manifold pipe and one U-bolt holding the other end to the muffler.
This doesn't strike me as the best way to put them together. I thought maybe they should be welded together or something so that there's no leaking.
Is it normal to attach a catalytic converter using u-bolts? Or when i replace it should I have it welded?
