Passed CA Smog again w cat bypass pipes :-)

[Johnny Danger]

I don't mean to be answering for Chris, but there are very few choices when it comes to aftermarket by-pass pipes . Fabspeed and Schnell are two that come to mind. As far as performance is concerned, deleting the secondary cats will improve exhaust flow and seemingly give a slight "bump" in engine responsiveness. Most importantly, however, it reduces a significant amount of weight from the vehicle.
