The price and no performance issue have been well documented and have made me think that the Racing Beat is the way to go. Here in Cali the RB is CARB legal, it looks fantastic, and the quality is top notch. I personally don't mind paying a few bucks for something from a company that makes parts for our cars and Mazdas in general, and goes the extra mile to get them smog certified. Not an issue for everybody here, but not all of us here in the golden state want to switch back and forth between parts.
