Warranty and performance
Does such a thing still exist?
Is there a company that offers full exhaust and intakes that won't void the factory warranty? I'm looking for the best set up to make some better noise and retain my full factory warranty. Not looking to go crazy, make any huge power or go to track. |

No, but the Magnuson–Moss Warranty Act should protect you, in theory. There are issues, but if you have a good attorney you could be good.

Carbahn will sell you a warranty for many of their products, including tune, where they will match the factory warranty.
Take a look through the tuning sections and on the Carbahn website. Carbahn is owned by Steve Dinan who, well, founded Dinan but sold it a while back to focus on racing and is now back in the game. Aside from that, it's pay to play and completely up to the discretion of your dealer. |

Take a look at this YouTube channel. CarGuy302 gets the Stage 2 from Carbahn, Dynos and draggies it before and after. That's your best bet if you are after more power and still want a warranty

But even then, it's always in the back of my mind that you never know how those aftermarket manufacturer warranties will actually play out until you have an issue.

You should not have a problem with those mods. Catless DP could be an issue. Back in 2017 I talked to the BMW-NA dude when he was there to look at my fucked crank hub. They would not start to repair my car till the guy came. I knew it wasn’t covered, told them I was paying but they could not touch it till he denied warranty. Lame. Lol

OP, if you want to leave your BMW warranty intact, stay stock. Otherwise you are rolling the dice. You can certainly ask around your local form or groups or whatever for who is "mod friendly" and that will increase your chances. |

It’s will cost more in attorney fees then fixing the thing. People who say that have not retained or pay attorney fees in the past…. I think some minor mod dealer would not care but if you are modifying exhaust system significantly and gaining HP in the process why should it be covered by warranty? Not to mentioned you are probably violating some emission standards as well. |

For things/repairs in the $0-$10k range, that's small claims (sometimes more. In GA it's $15k). You have the option of filing that yourself, and it's a minimal amount of effort to present evidence to back up your support, and the file fee is quite small in most states.
This kinds of issues, the warranty providers *always* end up losing, so they're likely to cave after learning you've filed in small claims court. Your obvious least-path-of-resistance is just working with the dealer in the first place so it doesn't have to come to that, but the law is clearly on your side in these situations. |

I believe it tends to be less expensive if you do it before you hit 20k miles.

Second I would not rely on u gonna win u have no idea how that’s going to play out. Third how u going to explain that catless downpipe and modified exhaust is no problem given u are violating state and federal regulations and altering vehicle performance. Dealerships get paid by BMW for these repairs they don’t care if u filed small claims. They have nothing to loose. |

People really need to read up on the Magnusson-Moss act before suggesting it as a scapegoat for aftermarket (off-road only) performance parts.
Below are some reading materials on this topic that doesn't involve SEMA's deceptive explanation: A. https://www.ftc.gov/business-guidanc...#Magnuson-Moss B. https://www.yourlemonlawrights.com/m...s-warranty-act C. https://www.autocare.org/government-...s-Warranty-Act |

BMW says: Your aftermarket modifications significantly increased exhaust volume over and above what the car was designed for. You are operating the vehicle in a manner inconsistent with design and that directly lead to the issue. Therefore not covered under conditions of warranty. What are you going to do, say "i know better than you"? You'd have to hire expert witnesses, run tests and have knowledge of what the original BMW design parameters were and if you've exceeded them. Yeah, you're not winning this unless you go deep into $$$ at which point you might as well just pay up for the repair as it'll be far less. Which BMW knows when they tell you these things. You mod, you take the risk of 100% liability. You might get lucky, you might 'know a guy', or know a dealer who is actually respectful. But you always are running SOME kind of risk. It may be your day to get pulled over for 40 in a 35 because some cop had an argument with his wife and spilled coffee on his shirt that morning. Do people drive 50-60 in that 35 every day and get away with it? I'm sure they do. But it was your day... |

I'm specifically referring to statements like this: Quote:
However, even for my first paragraph in this reply, the M-M act is very clear in its presentation. You can read the law yourself (section C). There's also been plenty of examples of people successfully using M-M to win a case against denied warranty claims, and even to BMW, and even on a similar topic to what we're talking about now. I will agree that out of all the mods you can do to this car, tunes and exhausts are probably the hardest cases to win. |

My SA said that intakes and exhsust don’t void warranty. Just don’t ask them to replace down pipe gaskets under warranty if an aftermarket exhaust is installed. Same thing if you break something under hood while installing an aftermarket intake.
