I just want to know some info about headers, well what are the best brands? do they really add noticeable power to the truck? Are they worth the money?

 

They will add power, worth the money especially if you plan to more power mods. Pacesetter is probably the most popular right now because of price. They are long tube, and come ceramic coated. They will delete the cats, and they have an optional y pipe that bolts right to the stock exhaust or aftermarket cat back. You can get the headers for 300 shipped, and the y for an extra 135
