Hi, I’m a novice w cars but I’m in love with my LC500 2018 I just purchased used but low miles. The exhaust note is addicting especially the down shift rev matching? The car really growls and gurgles if you will, it’s intoxicating. Twice now I’ve taken it out and it’s like some how I turned the ”snarl” off on the downshift?!? Has this happened to anyone else? It’s disappointing when you have it timed to go off next to the pretty girls house and nothing! But then it mysteriously reappears after a bit. Just wondering, sorry for rambling description.
