I have an 02 envoy and have a JBA cat back exhaust on it. It has been driving me nuts with the drone. I am thinkin about replacing the JBA muffler with something different and quieter. Maybe a Flowmaster or an Aero Exhaust stealth muffler.

Any suggestions which on would be a good choice.

Any help is greatly appreciated.

Thanks

The JBA has somewhat of a resonator in the last 12 inches before the tip. Although it is only a half inch of packing around the pipe. I am thinking that i am going to start be quieting it down a bit first then if I have to add a resonator I will as needed.
