O.K. Here's my suggestion, before buying our rack conversion I would talk to Stan and see if he would like to modify them. He may want to use you car as the setup mule. As I don't own his business I can't speak for him or gaurantee he'll do it. I want to be honest here I really don't want you to buy our rack conversion unless you understand there might have to be some mods done to the headers. I'm just won't sell a product by telling a lie so I get your money! Not a good way of business to me. I've have three customers with 60 Starliners, two of who I talked with after the rack install, they told me the really could not beleive the difference in how their cars drove.
