My guess, is that if you use these downpipes, AND replace the other cats in the exhaust system, you might have a chance of failing the sniffer test, as well. That's why I generally prefer high flow cats rather than straight pipes. |

I made doubly sure I got the hi-flo catted version of AR DPs on my e89 N54....it just sounds way too farty catless and I wanted the car to stay legal and eliminate any chance of it smelling. Even with catted it still sounds slightly raspy on full throttle but only when the exhaust system is cold. The total price for a twin set of AR Design catted downpipes was way less than $1350...USA handmade and finished etc.

I don't understand why people in the US would put downpipes on if they don't have a tune for at least getting rid of the SES light for inspection. I learned that it's really not worth the headache of switching it back to stock and then back again after inspection. If there was a downpipe fix out then yeah... But there are non ... Still none for the n55!

States like mine [PA], and probably why it doesn't appeal to me with out a fix... is that i have to do it every year! Even on a new car but i guess thats how we keep the economy going. |

and I agree with you, I wont be adding catless DP to this car. much less for emissions reasons as with dealer reasons. here in texas they will F*CK you over for anything they can, so no chance im gonna mess with that. not to mention that the sound is all jacked up and raspy without adding additional resonators, so that adds more mods and on and on and on..... |

Sound aside, it's illegal for a dealership to refuse warranty work because of an aftermarket modification unless they can prove beyond reasonable doubt that that mod caused the issue. If a dealership gives you crap for something like this, go somewhere else.

everyone says this, but its a lot different when the dealer flat out refuses warranty. no dealers in our area are even remotely friendly towards mods, nor do I expect them to be. |

It is perfectly legal especially an illegal modification even under the Magnuson act. The owners/service manual also states that they can void your warranty if you modify the vehical making it legal to do so under the magnuson act. When you purchase the vehical you agree to these terms Repairing and modifying are different.

Very nice looking parts. Suppliers will change what they think will maximize total profit. That makes for the eternal "BMW tax" on parts like these. Of course, that being said, don't mistake me for one that doesn't support capitalism...

My AR DPs are black ceramic coated with the high flow cats - I love them. I think they were about $1k. No lights are thrown, power is up, and sound is really good.
