I understand completely. If i wasnt so knowledgeable about cars and had experience i would feel the same way. Im here to help. Being 100 percent honest here about the OBX and you. Stay away from them. If you dont have a welder, bandsaw, time to mess with them, they arent worth the $250 savings. The ports line up fine, they are cnc cut flanges like everyone else. The thing thats wrong with them are that the crossover doesnt line up, you need to cut it off and reweld it a different position. You also need to weld the other connections as other headers have also. You need to finally cut off the front egr port on the front header flange (they used the same header flange for both front and back, and it interferes up front), and need to drill the egr out to 5/8"; its too small when you get it. Other than that, they are great, stainless headers. If you dont have the tools/ experience stay away, no offense.
