H or X CROSSOVER?

I talked with Doug Thorley (RIP) hisself several times many years ago and he could not tell me enough about all of the chassis dyno testing that they did showed little to nothing and that he, like I do thought that it made the exhaust much less crisp. He described it as a blahhhhhh sound. I 100% agree with him. IMO, it takes something away from the exhaust note. He basically thought they were something shiny to get people's money. I must say, he was a real hoot of a guy to talk to.
