My dad has a '96 Corvette Collector's Edition with the LT4 and a B&B exhaust system. The resonant drone from the exhaust at 1500-2000 RPM is really obnoxious, and it's right at the 70-75 mph mark in 6th gear which is the typical highway cruising speed. He's been talking for years about replacing the exhaust or mufflers to eliminate the noise, but the exhaust sounds so good at all other speeds that he can't bring himself to change it.
