I did the res delete a couple of weeks ago and it is awesome!
In N mode it growls and pops when you start up from cold - it sounds like a rally car.
In Normal mode it's just as refined as before so no downside.
Car measured 97DB static at the track day last week in N mode (it was 94 before).
Love the gurgles on the overrun most of all, sounds so deep and aggressive.
I took a mate out today in it and he said it sounds like a rally car, he couldn’t believe how much louder the bangs were, but yeh the gurgles are the best, it’s sounds pretty nasty.. I’m not so sure I’d let this baby rip with a cop close by though, I’m no expert on noise level legality, but I’ve got a feeling this may qualify? lol, so I’m happy normal mode hasn’t changed all that much..
