Fellow M Performance exhaust owners, I am at the edge of shelling out another 7000+$ to BMW, but before I do that I wanted to ask: The MP exhaust is not valved right? Then would the car be loud af at all times even when I put it into efficient/comfort settings?
There are certain scenarios where I would like the car to be quiet...or am I better off with a Fi system? |

Correct. The BMW M performance Ti exhaust is made by Akrapovic. It has dummy flap plugs for the valve meaning it is NOT valved and is always loud.
If you want valves get the Akrapovic Ti aftermarket exhaust with valves |

It’s too bad that BMW doesn’t offer this for the M850i
The $300 muffler delete is looking more and more appealing. I’m just waiting for @Vic55 , aka my “canary”, to tell me how it goes Vic, you’ve got so many nice cars you can afford to screw one up. This is my DD!! |

If it does have valves then it would be a no brainer for me. Guess another 7000$ out of my account |

IMO these after market exhaust are WAY over priced. WTF do they have that's worth 7k or more in these systems? Performance wise they seem to offer a pretty small increase compared to the cost to do it.
I liked the $200 dollar mod. I think it was Vic55 who did it?? You want more sound, do that. I know the tips option is a big part of it. I get that. But 7k is a lot to pay just to see a tip change. That 7k is actually more like 9500 in Canadian dollars. Plus shipping...nope. Not a correct value there to me. At 4K i might consider it. I like the Dinan $200 option for remote valve opening. On occasions I like more sound too. But not at those prices for full exhaust. ?Then I read some guys swapped them out and still weren't happy with sound |

I don't think anyone can because they don't have any... Here is the M8 system and it comes with the dummy clips to keep the OEM harness safe.

My Alfa Romeo Giulia had mufflers removed and the shop said on turbo cars just mufflers out won't make a big difference and that was indeed the case on it. I didn't keep the car long so I didn't care but same concept on this in which case remove the mid-resonators might be the way to go for enhanced sound. That and quad tips is all I would need. Haha. |
