Your either buying parts you can't use if you get a full 08+ cat back if you want to use these headers.

Best bet if you really want to use these, your borla rep headers, 06-07 high flow cat pipe, 08+ AXLE back. And have your local muffler shop fabricate a custom 2.5 inch mid pipe straight through pipe. It would be completely one off and a unique awesome sound. Getting just the axle back will offset the price of having to buy high flow 06-07 cat pipe.
PM'ing you
