size & "H-pipe"

I don't like any kinda crossover. I'd love to see independent testing on them. They make the exhaust sound less crisp, IMO. I spoke with Doug Thorley many years ago, and he said that in some instances, they actually lost HP and TQ and that he preferred exhaust systems without them.

The only information as far as testing and dyno specs I've seen on them are those from the companies that make them, or from magazines that those same companies sponsor. I would be really careful spending money on anything where the only evidence of benefit has a direct impact on sales.
