Just got the car back from the Exhaust shop a few day's ago. They fitted the TSR 4-1 Racing Header, High Flow Cat and fabricated a custom Stainless Steel exhaust for the car. They had to extend the wires for my lambda sensor so it would reach it's new home. I have had no problem's and best of all there has been no CEL'S. The car pull's a whole lot better now.
