Std with Downpipe = weak (you hear the engine too much)
Second video first half sounds ok, Second half with valves open sound like M40i (not louder) also this car has downpipe so its suppose to sound louder Quote:

Time out:
-I am happy with my Klappen and you all will be happy with your M40i. I was afraid that my vehicle, with only 306 bhp would sound "weak" compared to the Russian car - but on the contrary - in reality it has a stronger sound than video - both legal and non-legal. If anything - M40i has somewhat stronger sound compared to legal, but non-legal is King of the Hill Anyway, I am now driving with a smile on my face- just waiting to remove studded tires. |

ROBNYC,video is out of my league. You have Russian car and M40i - both in "garage"- you have to trust me that STD 35i with Klappen is as Russian car.
I will, however, do a tesdrive with M40i at dealer, when available. I will also report findings here - not to try to convince M40i owners that they made a mistake, but possibly guide potential buyers of the difference between an EL Cheapo upgrade of a 35i and a M40i. I am happy with my 306 - possibly 315bhp with Klappen - so the interesting evaluation is: -interior sound -sidewind sensitivity -steering precision -steering feedback -steer-into-a-curve -gearshifting -chassis comfort Last edited by Tjalle; 02-29-2016 at 01:27 AM.. |

Am I the only one?
There are no more X4 35i being produced. Klappen was designed for X4 35i M only. There are a lot of positive appraisal for the sound of the M40i, but so far nobody has come forward with a report from a 35i M with Klappen. Am I- and the Russian - the only ones? |

Apparenetly for the M Sport not the X4M
The exhaust sounds about what my X4M sounds like on "sport and sport+ and sometimes on normal when flooring it. AC Schnitzer has a new rear diffuser panel for quad exhaust that is for the X4M although it should fit any X4. It also comes with the exhaust "finishers' ie tips.

SANK ,me and the Russian! I understand that 35i is no more- like the parrot.
ROBNYC, very impressive - I consider it a tie, with my illegal setting - you have more blurps - I have "larger/stronger" note See 2:d Russian video in Track-mode. elimpfor, you are home free - the question is: how did BMW get away with this "noise" in the certification test? |

elimpfor, I fully understand that you are happy. I referred to the legal testing of exhaust sound, where there is a noise/sound limit. Toughest requirements are - I believe - in Europe
I have worked for a car manufacturer, and we would not have got away with this level of sound. Perhaps BMW learned something from VW? That, however, is not your concern. You just enjoy! |

m7mad, there are a soundclips from "Russian car" with STD exhaust, Klappen-Sport, Klappen- Track and also "Russian" being dyno-tested. All in this thread.
What has not been discussed in this thread is the fact that M40i has electronically enhanced interior sound -that has been established elsewhere -and that's how BMW got around legal requirements. What is heard inside is a recording of outside exhaust sound. Very impressive but not the real thing- which I have Many believe that 4 exhausts are the way to go - I believe that is over the top for less than 400bhp. |

chentw, finally! You are the first, besides the Russian, to say you have installed Klappen/M Performance.
There has been numerous inputs on downpipes - hope someone will help out. FSociety should know. |
