Might have to give this a try. For the life of me cannot fathom why BMW slacks on the exhaust tips for the 8 series or any series for that matter.

This no doubt a more expensive mod for a similar effect to what you posted just removing the trim and adding new exhaust tips.

Details on my post, this topic came up on this Facebook group. https://www.facebook.com/groups/159538091567413/ The poster with the sunset orange car said this: So, after a few trial and errors here is what i did, so you guys don't have to waste time and money. I bought mine from Ebay and the sizes that were perfect for the stock diffuser are ID: 63mm and OD: 101mm. There will be some welding and cutting but any weld shop, muffler shop, mod shops should be able to do it. Also, make sure you remove the square tips before installing.

Look at all the tiny clips and holes and slots and attachments that has. Bump or jar or hit the bumper even slightly and I bet they break like saltine crackers. They all look very very delicate to me. and you say a rear bumper is worth what? in $$$$ Note to self....don't even be less than ultra careful backing up to anything. Looks great on the A side but ultra damageable on the B side. |

The only thing the muffler shop did was cut the four pipes off the muffler and removed the exhaust flaps. After that he bent four new pipes, welded the flaps back on and reattach pipes to the muffler.

Okay so making me think the guy I was talking to just wasn't clever enough. I'm assuming the pipes he refitted were straight/circular to fit the new exhaust tips? Shape of the tips is the 2nd thing the shop guy kept getting hung up on with zero solutions.

Thanks for posting this. Tried to navigate that fb group but half the comments won't pop up for me so kinda pointless

3 shops later was able to get it done. Wasn't able to get any pics of it on the lift. Had to leave it with them and pick it up the next day bc of scheduling. Happy with the results. Some quick pics once I got her home. Shop said never again, one and done

Questions: 1. You went with Netami tips. What size and what source? Why did you choose them? 2. Is that the stock diffuser (without the trim piece)? It looks a bit different. 3. What did you do about the flaps? 4. Why did the shop say never again? 5. No sound difference, correct? |

51-12-8-075-246 is listed as the rear valance PN for 2019-2022 840i and 850i coupes. 51-12-8-075-300 is listed as the PN for the Grand Coupe. The trim rings and the bumper PN's are also different. Curious if the coupe valance would bolt right up?

Yes it's the stock diffuser for the M850i Flaps are still intact Too much work for them. They don't plan on offering it again to my knowledge Maybe slightly with sound on cold start but not super noticeable. Edit: After a few days with her the cold start is definitely louder, way louder. No, didn't delete muffler. Looking at the new exhaust pipes they welded on they're quite a bit wider/thicker than the stock ones. Don't know if that has anything to do with it but the new growl is mean, I'll take it.

Got my tips installed today. Some pics during the install process, lots of cuts and tweaking. Dropped car off at 8:30AM was done at 3:30PM. Lots of work but no complaints from the installer.
