The paint is just cosmetic. The pipe is stainless steel which will not rust. Before painting, scuff the area with 100-400 grit sandpaper which will provide "teeth" for the new paint to adhere to. Mask off the edges and spray away. I would certainly do this before leaving my car with the dealership and risk paint chips or other possible damage.

Does anyone know if they have improved the paint on the newer tailpipes? I've just purchased a used approved M40i and part of the deal was that they look at the l/h tailpipe that was flaking. They are putting a new back box on before I take delivery now, I'm just wondering if its going to happen again on the new exhaust.

My concern is to find a paint color and right gloss level (Matte I think) to match the other side, which is not flaking yet. Anyone found one that looks good, please share your experience. |

I had a Range Rover and had to paint the back box. I used a specific exhaust paint after roughing it up with a metal brush and drill.
This is the UK one, sure there is something similar in the US. https://www.halfords.com/motoring/pa...ic-black-300ml This was the metal brush https://www.halfords.com/workshop-to...cleaning-brush |

First wash yesterday. I wasn't supposed to go through a car wash with the roof racks installed. Washed by hand with a garden hose. So definitely not a pressure related issue. My right pipe is flaking just like OP's image. I can't feature my old bones sitting down and sanding in there... I'll try black shoe polish. 🤨

Curious... MechX, do you know if an out of state BMW dealer will do my 3 year service? The dealership gets paid, and does that regardless of where I bought it (??) |

With few exceptions, I have found that the squeaky wheel gets the grease. Keep pestering, ask for the GM's contact number, etc. Once it is clear that you are not going to nod and defer to their 'wisdom' then you can make progress. You won't always get the result you are looking for, but push until you really hit a wall and then re-evaluate. I try hard to let little things slide, as I just don't want the hassle of fighting with a poor service dept. |

I'll be contacting a Kentucky dealership soon, just to touch base. I'm hoping they might see me as "customer". 😎 |

Luckily, so far, I'm not worried about gray areas. Just the 3 year service (oil changes?). That ain't a gray area. My central Illinois dealer is only in the business of selling a vehicle ONCE, and not doing anything after that. So, I don't even want them servicing it. I know the service guys are removed from the "client advisers", but nevertheless... Seems stupid to come back in when they don't want you there. |

Can't believe my right tip started flaking...car has 1,400 miles on it. Just a small piece so far but now I see it every time I look at the car. 2019 model year, built in October 2018. Given that replacements seem to have the same issue, I don't really know what to do. Should I go to the dealership right away or wait and see if it gets worse?

I would go to the dealer right away and get it replaced. It's only if this keeps costing them that they will finally come up with a fix. I had a new exhaust on my used approved car for this issue.
On a side note does anyone know how the left hand valve actually works. Does it only open when driven hard as I have been checking it for heat and most of the time it's stone cold even when the car has been in sport mode. It has been hot a couple if times so it works I just can't make out when it works. |

As I mentioned in my broken window post, I asked the dealer to take a look at the driver (left) side exhaust which has the flaking issue on the interior of the exhaust tip. They are going to replace it.

Will they replace a 2nd or 3rd time when those start flaking? Doubtful...fixed mine with some bbq flat black spray paint a couple of weekends ago. You'd never know the difference. And when they start flaking again in a couple of months...more bbq paint...3 mins in the laneway every few months vs. multiple trips to the dealer and be w/o my car for x # of days...priceless
