Please advise whether the 435 exhaust note will change after the break-in? I can't believe that I have to spend more money to make this already expensive car sound better!
Anyway, here r some pics:

So many stock exhausts sound timid.
The good news is you can fix it.
Wait until you hit 1500 miles.
Why? Statistically, if the car is going to suffer from a build issue it will show up in the first 1500 miles.
For this reason, most mods should wait for 1500 to ensure you're past the build issues. Otherwise, tinkering with the car during the time it's most likely to have an issue will just make resolution more challenging and increase the likelihood of finger pointing.
