Anyone driven a M5 with Competition Package?

I just test drove an M5 and just before I was getting in I noticed that it had Competition Package - which is not something I'm interested in because of the added cost. From the moment sales guy started the car, I noticed the exhaust was notably loud - too much rumbling sound for my taste. Sounded like the typical aftermarket mods people do to their civics. Even after the engine was warmed up, the rumbling sound didn't go away. The reason I was surprised by this was because I didn't notice this kind of sound in any of the M5 videos I've seen on youtube.

Can anyone confirm if this is specific to Competition package or is regular M5 this loud on idle as well?

By design - the Comp package is louder than the M5 w/out the Comp package. The Comp package is exhuast/wheels/brakes/bump in HP.

I have an M5 with the Competition Package in production, but haven't heard one in person yet. Aside from the change in exhaust tips to black, the ONLY change in the actual exhaust (that I'm aware of) is removal of the baffle. Most (not all) M5 owners have been a little underwhelmed with the stock exhaust note (especially with the artificial speaker note piped in). The ZCP option is there to give it a throatier, more aggressive sound. Again, I haven't heard one in person, but that louder cold-engine start sound should still subside/lessen after a short-while (when the exhaust valves close). Even still, some enthusiasts (many who are basing this on video alone) don't feel the ZCP exhaust note goes far enough (they seek the stock AMG C63 type sound). Personally, I want my M5 to have a fairly aggressive sound. The M5 is a special beast, though, as it walks a fine line between comfortable luxury and intense power. Therefore, it's hard to please all buyers, but I think BMW does a rather good job.

For the M5 without the comp package, the rumbling quietens down after one has put miles on it. Also, the rumbling is significantly louder in a (partially) closed environment.

It sounds just like my LCI, I have wired open the exhaust valves, and that does the same job.
Sounds very loud on start up cold but OK for the rest of the time.
I have the CYBA tips also, so just looks and sounds the same.
Driven the Comp Pack car and frankly NO real everyday difference at all, the steering has been enhanced on the None Comp pack LCI's as well so my steering is great.

Do you have the video sound clip I can hear while the valve is opened? Did you mean the flap from inside of the exhaust? If you leave the valvue open all the time.... does it generate any warning on the computer or else?

Thanks.

Is there any instruction I can find to wire open the exhaust valve? Did you need to jack the car up to do it?

Thanks.
