    Less restriction is better. Stay with no cats.

    ? on power loss with cats. With no cats should you go with true duals then.

    its not robbing you of power but it will make your car smell like its running rich. But a good tuning can take care of that!


    only run duals if you never plan on doing a turbo build!
