I think it’s loud. The day the 4:1 it was installed I was convinced there was somethign wrong. I had a brand new H55F installed at the same time, and I really thought there was no way this noise could be normal. Lucky for me, Georg happened to be in town and took it for a spin and told me that’s normal. It’s been over a year now, and I’m used to it, but I still don’t love it.
It’s not a constant whine. It gets louder/softer depending on RPM and whether it’s coasting or pulling, at least that’s my perspective. But, windows down, putting around at 40 - 45 MPH, it’s pretty annoying.
That all said, off-road in 4 lo, is so great. I can’t go back now. Although I am very much considering going not 3:1 and then adding a doubler of some kind. The only thing better than 4:1 would be…you know… 6:1.
If this was my daily, I would not survive with the 4:1. I’ve gotten soft in my old age, and my 200 has spoiled me.
