When products like those manifolds are copied and undercut before they are even fully released, no one wants to spend the time/money to make better stuff. I don't have to repeat it to you, you've already seen vendors/innovators cancel new products as a result.
Instead they move on to the next new car and hang on for as long as they can there. And people wonder why SpecialtyZ has gone to SpecialtyX (Evos).

Avoid AMS Products - Killing Z32 product innovation, one quickly copied, questionable Chinese part at a time. SoCalZCrew.com - On a more positive note, come find out how we do it in the West!
