Same concept as cold air intakes, for example. Materials these shops use are the same (a cone filter, plastic intake tubing/box, etc.). Sell it for a Chevy and charge $99 bucks. Sell it for a Porsche, and charge $400. They think Porsche owners expect to pay more and can afford to shell out more. Marketing. Clever marketing.

Cat bypass will get you more results (headers even more) and shouldn't affect the CEL at all. We've got cat bypass for $495 - http://www.epiqautosport.com/pro_boxster_secondary_catalytic_bypass_pipes.php - and then you still have your primary cats.
