Well, I got the resonator put on the OB today. The sound is much quieter and the drone is gone for the most part. I am however a little disappointed. The responsiveness that I wrote about earlier is also GONE!! I guess this is the result of restricting the flow. Anyhow at least the wife doesn't mind riding with me.

I often hear people with Flowmaster complaining of drone/resonance. I had the same with my Chevy (headers to dual Flowmaster). Later I upgraded to fuel injection and added catalytic converters right behind the header collector. That changed the droning to a deep rumble like the glasspacks this old guy grew up with. :)

Flowmasters are overrated. As a general rule, Flowmasters sound like crap.
