Personally I'm not convinced $1,000+ for the manifolds is worth it. I'd love to have a set, but I just don't feel the $$ is worth the minimal (if that) gain. I do believe the asking price on a set is fair due to the amount of labor that goes into them. It's your money though, not mine.

In other words, I'm too cheap to buy big dollar mods unless there is a documented performance gain.
