Have you had someone rev it for you from the outside? Stock I louder than I thought.
The interior is just really well sound proofed.
In my m2c I ran with the back seats down at all times for more volume, maybe give that a shot too. |
Great idea on the backseats down - thanks.
I'm going back for secondary cat delete later this month.
Sport plus is much louder than sport. Cold start sounds amazing. I just wish I could have the cold start sound all the time.
