on the newer ones 97-2005 get under the car and find the cat converter and follow the exhaust pipe up on the passenger side into the engine bay. The rubber fitting is on the firewall here. Not too far up about a hand length. I read it detaches sometimes. pull it off and there is a plastic pipe it attaches too. I blew out the pipe with a little compressed air and rtv the rubber part back on. Hope this helps.

The 1997-2005 Buick Park Avenue's and Park Avenue Ultra's all use the same bumper cover part number. So I think the bumpers themselves would be interchangeable.
