Hello:
i'm back from vacation and got the replacement resonator installed today. I have not driven it enough to say for sure that there is a difference between the original Magnaflow resonator and the replacement Vibrant bottle-style resonator. I will have to drive some more to really get a reading.
It's such an inconsistent experience. On throttle, off throttle, steady state, accelerating, uphill, downhill. Elevated drone can occur during any of those combinations of conditions, but always centers around the 3500 RPM range (gauge might indicate anywhere from 3000 to 3800ish). In the short drive back from Muffler King, there seemed to be incrementally less drone in the target range, but the exhaust seems slightly louder under acceleration above 4000 RPM. Just from my gut sense inside the car, so take that with a grain of salt.
It is what it is. Under 3000 RPM, the car sounds smooth, from 3000 to 3800 (anywhere in there but usually closer to 3500) you can get a loud drone. There's no getting around it. It's there. Is it associated with the SS construction? Is it the 3-inch diameter pipe? Is it the shape of the exhaust system? Is it the resonator? I have no idea. However, anyone out there that wants to quiet down this exhaust, I would definitely see about getting that bigger, oval-style resonator. It might cost more, but if you want to minimize unwanted drone, it might be your best bet.
It would be good to hear from whomever actually purchased that one (instead of stuntdoogie).
Joe: I appreciate your efforts to resolve this situation. I'm going to live with it and see how it evolves over time. I don't think my wife will like riding in it, which is unfortunate. In any event, I need to contact your admin regarding a shipping label to send the other resonator assembly back.
