Then slip on the flanges and then weld the bungs in. When making 50 sets yes it is easy for the cnc bender to do it. But when making the first set it is very time consuming and expensive.
Really try not to look at how much it costs just for two pipes. The gain in power is where the money comes from. If it was worth 5hp no one would spend the money. I dont see people complaining about spending almost the same money for a set of pulleys that give you no where the gain of the test pipes. Are they over priced, yes they are but I also dont see people complainig about spending 6k on a evo system that makes no more power than the test pipes.

Agreed on all fronts.

To those that claim they can make their own for cheaper: well what are you waiting for...
