Check inside the driver side exhaust tip if it's open.

Great, thanks, I'll do this and see how she sounds (I have M Sport exhaust on as well)
Does it throw code errors on ECU? |
It's going to sound like you're in sport mode when you're not.
No errors that light up on the dash.
But I realized that even with this mod, sport mode still seems louder which is probably the fake engine noise piping through the speakers.
