Just wondering, being a machinist myself I dont see the reason why some cost so much more than others. Especialy if most the work is done CNC. But then Ive never made one. I understand some are better than others but what is the reason for a 500 to 600 or way more dollar differance? So what does drive the cost up?
Some of the cheaper models are made with plain aluminum or carbon steel. Your higher dollar cans are made with inconel and titanium which are more expensive and harder to machine (therefore more expensive). That is one of the reason why some cans are rated for full-auto and others are not. Also, like dustin mentioned earlier, you may have to go through several different variations to come up with the maximum sound reduction. All of that R&D costs money.
