I have the circuit werks resonated test pipes as well on my '99 and love them except the occasional catless smell when stationary w/ the windows down. I've had them on for about 2 months with the O2 sensors hooked up to them and still no CEL. Also running Soul Performance's valved muffler bypass w/ oem muffler so she can get rowdy with the press of a button!
