Keep in mind that I'm a new owner with only 400 miles in the seat, but I just noticed something yesterday that was interesting to me..
You know when you first start the car up cold there is an explosion, all 4 exhaust valves open, then it closes 2 going into normal mode.
Yesterday I noticed starting up the car (when it was already warmed up) that it was not the same explosive sound, obviously only 2 exhaust valves open.
Anyone know the mechanical reasons behind this?
Just curious.
