Though I do agree that other than the burbles, that exhaust sounds like any I6 F30. |

My X3 M40i also sounds like this in Sports Plus mode. The engine idles quite loudly when cold regardless of the drive mode; the down side is that you can't sneak out of the house without everyone in the house hearing the car, lol. M340 is tuned even more aggressively (382 vs 355 hp) so I would expect it to sound every bit as good, if not better!

Ah OK, I was actually wondering if Canada had different exhausts. In the U.S., all N55 and B58 cars receive the same exhaust. I believe all F30s in America have a valve in the exhaust.

Edit: I thought it was also the ECU injecting unburnt fuel and retarding timing. It's definitely controllable depending on what mode you're in. Last edited by praxis218; 10-11-2018 at 12:31 PM.. |
