At the minimum, there'd have to be some basic cutting and clamping or welding to get the LT's to attach to the Corsa X Pipe.

This is why if you're going to do headers, in my opinion, it is better to order the long header system from ARH or Kooks so your Headers + X Pipe are made by the same manufacturer, the long X Pipe from either will go to about the rear axle area where either the Corsa or Borla AXLE back will bolt on or easily be fabbed to attach with a little custom cutting/clamping.

I will attach a picture that may help demonstrate this...Just something I threw together in photoshop.

I want a jack like that so I can work on my car.
