    Cats in an X pipe...question

    I had my Long Tube headers put on last week. ( amazing btw). They ended up making a custom x pipe with True Dualz. Im here in Cali. and emissions are crazy.I have new hi flow cats sitting in my room. If i needed to put them back on for smog or if a cop pulls my ass over. Can i just stick them back on with the X pipe or do i have to go back to a Y pipe. Also you can add the Cats back onto the computer? Im a little tired sorry if im running on.

    you can put the cats in, but its easier to do it when the TD's are fabbed up. I had cats on my duals and it sounded great!

    I always thought cali law was, you must have cats in stock locations.. which ment you couldn't run long tubes anyway.
