Bad knocking under feet

I don't think I'd beat or wrap anything. Getting that pipe down a little lower would be the correct way.

Actually, from going back and looking at it, that pipe needs to be remade. Whoever made it, totally "missed" the exhaust pipe nook in the cross member. All it needs is to be bent differently so it fits up into the cross member. They totally missed the boat with that one.

How do I go about lowering it?
