I have the S type and no stock resonators. It was definitely louder than any videos made it seem. Mostly because videos just can't convey how loud things are without comparison.
But for me I like it. Was first leaning Touring then went up to the S type as I wanted it to be loud, but not as raspy as the Atak. Now I think i'd prefer the Atak as I want more rasp and pops lol.
But for me it has a loud cold start, gets loud under hard acceleration, but is also really laid back and quiet when cruising. Even when stop and go driving I can keep it reasonable if easing into the accelerator. Basically driving with the flow of everyone around me and not driving hard. I have no drone when switching to eco mode, and do have an occasional pop when going from eco back to full cylinders.
But I'd give it some time. You'll get used to the volume of it pretty quick and get a good feel for how to keep it tame and how to wake it up when you want to. Wide open throttle shifts are the best. And being able to cruise at highway speed with a quiet unassuming exhaust, only to step on it and surprise the cars around you. Is actually pretty fun to do.
