2. stock cat and muffler with Dinan resonator delete.
3. sport cat with stock muffler and Dinan resonator delete.
4. sport cat with Dinan muffler and Dinan res delete (current setup)
5. sport cat with Dinan muffler and stock resonator.
The current setup has the most drone, but I just deal with it and use a valve controller to keep the exhuast valve closed for most normal driving.

thanks for the reply. I'd keep valves closed to keep it down, just wanted to look into stage 2 tune. I love the way the car's throttle response feels now, but only in Sports+ valves open. Currently I measure average of 76db of drone on highway drives, wouldn't want to make it go past 80db (with valves closed). So VRSF 300 cell wouldn't be any different sounding than Wagner 300 cell or Fabspeed? No tonal different, just build quality?
