I never have liked the sound any type cross over produces. It takes away some of the crispness of the exhaust note. I guess if you're going for every ounce of power on the track, then great, but you'll never feel 15 HP on the street.
So Rusty, I often complain when I hear high performance cars that, as I describe it, sound like the exhaust is coming through a 55 gallon drum. I have always blamed it on a lot of the newer muffler designs, but is this what you are talking about? So is my criticism misdirected? Is it really the crossovers instead?
