Here is the link to FVD of North America. They have exactly what you want. Fabspeed also has a test pipe that almost looks like a cat which should work since the emmissions guys don't know all that much about 911s. By the way, I will be doing the 3.4 conversion to my sc 3.0 soon since I have just purchased the rods and crankshaft from a 3.2. How do you like it? Did you go Mahle? Of course it will be a much bigger difference on my car since it is 3.0. I just need a tiny hair more power, not too much, that is why I am doing it.FVDFabspeed

I have no idea if this will fit, but i've got a 93 964 cat that has been sitting in my garage since 94

What type of performance can you expect out of a "high performance" cat?
