No pictures for this part. I went under the car and removed the mount for the stock flex pipe because my header does not have a place to mount. I also disconnected the cat back and pulled off a metal plate and exhaust hanger just before the rear axle to let the cat back rest on the ground.
Now I pulled the header off. To get it to fit out I had to drop the engine a bit by disconnecting the passenger motor mount and pulling the middle stud for the header. Lowered engine with a jack and after a few cute words it was out.
Now everyone told me that the o2 sensor is too short and I need to buy the Porsche one, but my car is currently running on the stock o2. I took the sensor connector off of the bracket on the valve cover and rerouted the wire and then it reached with enough slack for engine torque.
I believe you can pass with just one (aftermarket too) cat where I live in NY. Its tempting to buy a header and have a shop weld a cat in some where for a full legalish exhaust.I'll have to see how much the sound increases with the ST CBE before I consider anything else though.
