Question about loud rattle on the mesh of downpipes
I have a 2017 M2 11,700 miles on the odometer. I have a dinan resonator delete pipe and dinan muffler installed. About a week ago I recently been experiencing a loud rattle around 2500-3100rpm. Its gotten so annoying that I had it checked out at the dinan installer that did the install for the mid pipe and the muffler, they found the mesh around the downpipe is rattling.
Has anyone experienced this with my type setup?? If not will this cause problems for me down the road either way I am going to get it fixed but I am hoping that the dealership will cover it. Just a bit more information the down pipe is O.E.M and not aftermarket. Any opinions or advice would be greatly appreciated. The rattle is driving me crazy. |

Update to my rattle
Quote:
Here is his exact quote: "Looks like the noise is normal. There is less back pressure in the exhaust and it's causing the wastegate to rattle. It's not the downpipe at all but can be heard through it. We can't change that". Great and the problem I am having with that is the rattle is getting progressively louder and I have read on the E90 forums that if it is a bad wastegate it will lead to future problems. Am I being paranoid or can someone suggest what I can do to get this resolved. |
