As scientific as I could make it: In the AM I had my car dynoed with "A" resonator. Took the car to a muffler guy I know who replaced the resonator
with an "X" pipe. Took it back to the same dyno same day and got the results Lee stated.

I kept the same mufflers because I like the sound.
More resonance ~1800 RPM but tolerable and worth it to me. JMO
