Do you know what size the stock 06-07 mid-piping is? Only reason why I ask is because I have a catback that is 2.5 inch and not sure if it would even work together.

I saw you coated your headers..any purpose or for looks? I will most likely just paint mine to help prevent some rusting and for looks.
Your o2 lead will have to be extended. It's a $15 part and then you'll have to solder two lines together and hear shrink the wire.

Stock mid pipe would be 2.25". BUT.... You'll need a 08+ cat back, it comes with a mid pipe that you won't be able to use because you need a 06-07 mid pipe. If you got a wider mid pipe it wouldn't line up with the back half of your 08+ cat back.

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.
