So I got a custom Y pipe installed (muffler delete or axel back system) and was surprised how much sound was being suppressed by the stock m exhaust system.
The small muffler/resonator after the OPF is in place to give the exhaust system a deep sound. I was surprised how much sound you can get even with the OPF in place (borderline extreme) with valves open. There is a bit of an air sound (engine pushing air through the system) when accelerating hard because of the OPF.
Video clip shows the car revving in comfort then sport mode (valves open) and then a drive from picking up groceries
. I had the exhaust valve closed while driving but the car in sport mode.
