Test Pipes
I have a fabspeed 70MM exhaust with 200 cell cats, can I swap the cats out for bypass pipes or will it trigger a cell light?

It depends on the file in the car. Some 200 cell cats will throw a CEL on more sensitive ECUs (early 997s, for example). If it's a factory ECU file, you can almost be positive it'll trip a CEL.

Hey Allen,
Since you have Todd @ EVOMS' tune on the Turbo, you will not get a C.E.L. with the catbypass pipes. These are a direct swap but we have to make them since you need the 2.75"/70mm outlet. Let one of us know over here and we can have the fabricators pump them out for you. Might as well do the headers too allow those turbos to spool quicker.
