Installed a cat bypass from Fabspeed on my 2000 boxster s, performance gain was noticeable but not huge, I did feel that the torque was improved at low end. The sound was excellent, but probably most telling was that my wife noticed that the car ran smoother, said it felt like the car had received a really good tune. I plan on getting a full Fabspeed exhaust this spring when I get done with my winter projects (replacing all 18 of the cooling system hoses, O2 sensors, change of trans lube, and replacement of maf sensor), so if you would like to try a cat bypass cheap, check with me around the end of March.
