I am running the Fabspeed Cat bypass pipes on my 2.7L 2000 Boxster and they dont bother the oxygen sensors at all. I am running them into a stock muffler. They seem to offer a little more sound when the car is pushed, and it is possible that they are giving a little more performance. But that is very subjective with no dyno data, it could just be the extra sound that makes it seem like the car is a little quicker.

BTW, I think I am going to take the plunge and get headers (no primary cats) and high-flow cats (with oxygen sensors). If I can still afford it I will also add a gemballa muffler. I expect this exhaust rig will make for a quicker car, especially with the Autothority chip that I will be using that is designed for this exhaust system.
