What is this?

I got this in a box of MFI stuff. Looks like a straight pipe to replace a 3.0 911 SC CAT. Dimensions are 11 inches long and 1 7/8ths ID. Weird is that it came from California where I though emissions would let you use one of these? Is it worth more than a six-pack?

Thanks

cat bypass for a rabbit? maybe for a 914, between the two original mufflers.

Not an SC cat bypass. It's a "Y" shape at one end mate up with the pipes coming from the heat exchanger.

That is a cat "test pipe" will fit: Porsche 924 and 75-76 914, And I believe john is right , It will fit early rabbits, Scirrocos ...etc.
