Amazing. As I said I wouldn't worry too much, you should be fine and get used to it. I couldn't go back to catted downpipes now because I enjoy the setup and power too much.

Give up bro. Just deal with it. I had mine reinstalled like 5x with new gaskets by 3 different shops, all reputable still rattles. I just drive my car in sports + mode all the time literally. Only annoying thing is when you valet and they drive the car up in efficient mode with a crowd everywhere and just rattles

I just got catless downpipes installed on my M6 and I’m experiencing the same rattle that hunter and others have had. I’m still unclear on what solves the issue. Is it just installing new gaskets that will reduce the rattling or is there more to it?

Hi guys,
Waking up this thread. I have installed catless downpipes to my M5 F10. After some minutes driving i heard this annoying rattle sound. After reading this thread i started to inspect the wastegate. And the rattle is coming from the arm. If i for example put a screewdriver between the arm and wastegate the sound dissapear. Im not sure if i installed the "dounat" right, how should it be fitted? I first put the ring on the downpipe and after that the flat gasket, pressed it togheter and screew it. (very very tight, had to be like three persons to hold it and screew it) I think that i may have put something wrong and it is so tight that it makes this vibrations so the arm vibrates, what do you think? The flat side of the ring, should it be up or down? I will also buy new rings. Funny thing is that the drivers side wastegate arm is vibrate very much and it was that side that was very very tight between pipe and rest of exhausr when installing. The passanger side was easyer to fit and the rattle on that side is very very small. Best regards, Calle from Denmark Last edited by Calle799; 06-24-2019 at 05:29 PM.. |

Hi all, Not trying to revive an old thread, but to help provide some guidance for future owners with the same rattle as the one in Hunter's video. Mine was making the exact same noise after installing Meisterschaft 90mm catless downpipes. Upon inspection, I determined that the noise was coming from under the car on the driver side. As the user (AlphaAlpineM6) tagged in this answer, it was more than likely an improper installation on my part due to not exactly knowing how this exhaust system is designed at the bottom. To fix without removing the downpipes again:
That seems to have solved my noise problem. Hope that helps! |
