If you want to use them, you'll need a older cat pipe from 06/07 2.5i's

They look like this to match up with the 90deg angle of your borlas

The 08+ are almost completely straight. If you haven't had the chance to look under your car this might look confusing. But the 08+ stock headers in the picture are mounted just past the second O2 bung, right next to the left set of exhaust inlet ports. Hard to see with all the heat shield. Sorry for the bad explanation, if I was on a computer I would just circle it.

Thanks for the help..I will most likely be taking the car and headers to an exhaust shop and having them make me a custom mid-pipe. More expensive but might be easier. If I go custom, will I have to do work for the 02 sensor?

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.
