I totally disagree for a couple of reasons.
1) I dont trust marketing from anyone trying to sell me something. "Tuned" is a great marketing sound bite and I think it probably is for more noise than power.
2) Manufacturers have been pursuing low NVH over performance and efficiency forever. Nobody is not going to buy a car becuase it is too smooth or quite but some people will not buy a car they percieve to be obnoxious.
3) An actual tuned exhaust would have a primary pipe length in excess of 40" (think long tube headers for a small block chevy)
