Actually they are illegal here. You are not allowed to change the manufacturers smog system. One forum member bought one and went to an independent shop to get it installed. The shop refused and threatened to turn him in to the authorities.

A mechanic threatening to turn in a customer to the "authorities" for a downpipe installation? This sounds like the Twilight Zone 😁.

heading in to drive the DCT and the Manual later today. I'm 85% leaning towards DCT because wife doesnt know how to drive manual... but I've been a MT boi all my life. so we'll see. After I decide, I'll put an order in for a euro delivery, or see if I can get a lower price on a euro delivery from BMW NW or BMW Bellevue.

Emissions regulations in all of North America tightly restrict the amount of sulfur permitted in motor fuel and by extension, exhaust fumes. If you're using an aftermarket, high-flow downpipe to circumvent these restrictions, wouldn't common sense dictate that it's illegal? You'll never get fined if you never get caught, which is entirely possible in many places and situations. However, The 1990 Clean Air Act Amendments prohibit private individuals from installing "converter replacement pipes" on their own vehicles that doesn't meet EPA certification. For the record, no high-flow aftermarket catalytic converter reseller currently have a EPA certification. https://www.epa.gov/sites/production...hsysrepair.pdf |

Perhaps you are confused between a catted downpipe and a straight non-catted downpipe? |

On a federal level, interfering with a stock catalyst that's fully functioning is illegal. Plain and simple. Now, emission regulations is enforced on a state level and depending how and if they enforce it, OB2 or physical inspection, you might be able to fly under the radar if your aftermarket cat doesn't throw a fault or they don't check for it. If you add an aftermarket downpipe, that doesn't change the fact that you're using a device to go around the set standards for pollution per vehicle. If such a defeat device was fully legal, all auto manufactures and companies like Dinan would jump at the chance to squeeze out a few more easy horses. BMW would have carbon fiber, M Performance sports downpipe for sale by now. Notice they don't? I'll tell you what, link just one piece of evidence that a high-flow, aftermarket cat is legal and I'll chance my tune. Until then, let's agree to disagree. |

Neither of these statements is true. As the earlier OP stated, it's the sum of the parts. If the emissions sytem as a whole, including the catted downpipe, as a part of the overall emissions system, meets federal standards for emissions, it's legal, plain and simple. The ENFORCEMENT, as was pointed out earlier, is to ensure compliance. And as long as the catted downpipe maintains emissions within set state and federal limits, it's not illegal. In either event, we all need to CALM DOWN! Last edited by ktmM3; 12-09-2019 at 02:02 PM.. |

So I guess this is why auto manufactures are only allowed to sell "cat-back" exhausts that coincidently stop short at the catalyst, thus not interfere with it .. Anything after the catalyst has nothing to do with emission compliance. Any and all piping after the cat is strictly for sound reduction only, NOT emissions. Legally, you cannot decat or replace the catalytic converter with one that is less effective than the OEM one. The end. CALM YOURSELF DOWN and find me some proof of anything you said. It's all conjecture and a pointless attempt in justifying your illegal downpipe. . |

I drove the white MT and the black DCT last week. Decided on the DCT. So I sat down to put in the euro delivery order with them and they wouldnt budge off of ED MSRP, so I walked. Bellevue said they would do ED mo problem so I’ll try them next, and I do have BMW Northwest waiting for an extra allocation to see if they can put an order together.
Just called BMW in Beaverton too. Just trying to find the best deal now... |

Seattle BMW has seven M2Cs in stock. I am sure you can get a deal on one of them especially at the end of this month. |

They dont have 7 in stock, more like 3, for whatever reason their inventory system counts cars not delivered yet, and accounted for cars. I’d prefer ED, overall. Havent done it before. edit: just to add I was there an hour ago or so to attempt to sign ED order papers. thats why I mention the inventory. Last edited by Tainen; 12-13-2019 at 08:03 PM.. |

managed to get 2% discount off ED MSRP by sticking it out, asking all dealerships within a couple of states, and then my closest dealership, after an e-mail from the GM and a respectful explanation of where I'm at, agreed to it. |
