The catalytic converter underside shield has started vibrating. I've just been under the car and only two bolts out of five still attach it to the cat. I've removed these bolts (one broke off) and I removed the shield. In order to refit it I will need to drill out the remainder of the four bolt threads.
Is it worth re-attaching the shield or can I leave it off and save a bit of weight ;-)
