I thought i would share this so other can learn from it , the best i can figure is that 2001 and 2002 calli and federal are the same , def welcome to a correction to that statement from some one who knows but what i found with buying a 2001 cali turbo was that they are the same , but 2003 and 2004 are def different , here is a pic of the calli gasket placed on a federal turbo .

i didn't know there was a Cali 01 and 02, learned something today i guess. I thought they were only available for 03-04 in like 13 states. i did know about the flange difference as i had a second-hand TTS downpipe that wouldn't bolt to the 04 Cali it was bought for....i definitely learned the hard way.
