The two different types of headers are longtube (off-road use only, ie illegal for street use) headers and the other ones are the shorty headers which keep the car legal. You'll get slightly better performance and a louder exhaust note out of the longtubes, but with the shorties you don't have to worry about being illegal, because they keep the stock downpipes and catalytic converters in place. The longtubes remove all cats. Hope that helps Oh and all the catbacks come with the x-pipe.
The Type S catback offers more hp?
