Chaps,
After having four fat boys (me being one of them!) in the meega at the weekend I bounced the front end down a bit hard off of a speed bump and since then the exhaust has been blowing >:( Anyway, I've had a quick look and theirs a tiny hole on the left cat, where the output pipe is welded to the cat body. I guess it flexed a bit and split the weld.
My question is this, can you weld cats? The body of the cat and the o/p pipe seem quite robust and weldable as opposed to the standard thin exhaust so I would think it's doable, but I wouldn't want to mess the cat up! And if you can is there any precautions to take with a car full of electronic gizmos? I guess removing the battery would be a good start but anything else?
Ta, Humpy

That's handy! Thanks Mark, saves replacing/removing the cat! :)

I may be barking up the wrong tree here, but I've never understood how disconnecting the battery will stop high voltage spikes and RFI damaging the electronics.
That was the main reason I used pop rivets to repair the door checkstrap.
Fire prevention if a cable gets burnt yes.
Surely a low impedance ie battery, would short most of the spikes to ground. Join the battery leads together after removing it?

dont know fella was always taught to disconect battery whenever you weld on a car !! ::)

You disconnect the battery because the welding arc will fry your alternator and it does work.
