Is the smog equipment for a silverado SS....or any other LQ9 powered truck the same as a 5.3 powered truck of the same year? I was mainly talking about escalade to a 5.3 powered silverado...I know about the cats and I would assume that the 02's are the same count....and in the same area....but what about the rest.....would all of the 5.3L stuff physically hook up to the LQ9 stuff?
