I know, I know, but without them you have a high probability of being totally screwed if you do this upgrade in Ca.
This set up is never intended to be smog legal in CA and we make no claims that it is, added catted DP's wouldn't change that fact, if someone is worried about emissions this is not the upgrade for you. To answer the exhaust questions there is no issues running 600+ hp through dual 3 to 2.5 inch Dp's keeping integration with most exhausts is important. If someone wants to go single they can.
