Nice! I have a TTI 2.5” exhaust with h-pipe and Dynomax mufflers on my road runner and the drone is unbearable at cruising speeds..... gonna try some vibrant resonators before the tips and see if that helps. Harmonics are crazy things.
I know Dynomax has an older YouTube video out where they mention using one of their glass pack race mufflers as a resonator. Might be worth a try if budget is a concern.
