I think that is what I am going to do, I just pulled my motor to repaint the engine bay, they look way to easy to put on, but where the collecter is located look like it might be a pita.
TTI sells an adapter pipe that bridges the distance between the collector and exhaust system. I already have a TTI exhaust system, they claim their shorty headers and pipe should mate right to my existing H-pipe.
I would love to see some numbers comparing the shorties performance to stock manifolds and standard headers.
