How does one adjust the hangers? Just with the rubber hangers or bending metal hangers?

For those of you who've owned other single 70mm exhausts and the EVS exhaust, how big of a difference is the low-RPM drone?

I have a PLM header, Hi-Flow Cat, and HKS single with the resonator. There is a huge resonance at 3-4k rpm under load. I love the sound of the exhaust everywhere else. How can get rid of that resonance? I know helmholtz resonators are for this, but has anyone done this and can maybe share some specifics? For example, I don't see space to weld in a helmholtz resonator.

Even helmholtz resonators aren't a guaranteed fix. There are plenty exhausts out there for our cars with helmholtz resonators that still drone around 3-4k rpm. The only real way to get rid of the drone is to get a quieter exhaust.
