Drone is pretty bad all the time. My helmholtz resonator was tuned for the previous setup. I didn’t consider the massive difference the heads and cam would make on the exhaust.. that j-pipe is really useless now. Lol. I have learned to deal with the noise. Only thing that is a bit annoying is, it sounds like I’m really getting into it, just taking off from a stop, normal ~20% throttle. So everyone thinks I’m racing them.
I have a little 18” magnaflow muffler, and the cats in the ARH longtubes.. no other muffler or resonator. (Other than the helmholtz, that’s completely mis-tuned now)..
