Sheesh 2 resonators and it still drones huh. I have just the 1 Greddy resonator it came with and it drones pretty bad too. To be real, I think that’s just how this exhaust will be since it’s like a 4.5” muffler/tip. Maybe try selling it and looking into the Greddy SP. I had that on my NA car and it was a lot quieter and it still looks nice, more of a sleeper look.
In my opinion not really, as long as you have a good tuner, and decent parts. On my old setup I was running a 1st Gen used Garrett G30 and made 380whp and 360wtq and it ripped still.
