Many 85-91 Corvette owners have complained about an annoying resonance in their cars that starts at about 1800 RPM and runs through, roughly, 2400 RPM (right in the 45-60 mph range). This problem has been solved by installing a crossover tube in therear Y-pipe. It eliminates the pulses that cause resonance. Simple bolt-in installation.
