They don't make power. If you're going to spend a fortune in labor to install headers (which are very good from the factory) you want long tube headers which preclude you running any cats. Long tubes are the only ones that make power. To make it easy, buy HFCs, Stillen Gen III intakes, your choice of cat back and a tune. That's pretty much the standard setup.
