question

well it looks like I wont have a cat. converter on the downpipe the way it seems from cobalt addiction since I am going to get the CA stainless steel headers v2 that comes with a downpipe unless it magicly has one already,now since the engine light will go on because of this situation,is there some sort of chip to trick the computer to think that there is a catalytic converter?So I can pass the bullshit edmissions later down the road

Nope you can't. The computer has specific intrusive tests it runs on the emissions system in the event of a believed cat failure. The typical simulator cant trick the computer when it runs one of the intrusive tests because the simulator is just not capable of generating the results the computer is looking for. Best bet is to save your stock stuff and change them out when you need to or have a shop cut your new down pipe and install an aftermarket cat.

Just use the stock cat until you can get an aftermarket high flow. Simple solution.

My turbo lag is your courtesy head start.
