Yeah I saw that video earlier. It's my favorite sounding exhaust, but unfortunately it drones like mad so it's not for me. I can live with a bit of rasp, I just want as little as possible.
I prefer the real deep, bassy and smooth notes of the Competitions (w/ stock resonator box) over the S-types, but I recently found out that they do drone a bit at 2K so I might go with the S-types since they don't drone.
It will be my first aftermarket exhaust purchase ever so I'm trying to select the perfect AB exhaust for me.
