NPT fittings have worked fine for me for about 3 years. I chose to go under the starter heat shield then on top the frame. But others have gone through the frame with success. It's not shown in the pics but I now have about a foot and a half of silicone heat sleeve that the lines run through under the header. HTH, Scott
