Catless DP Whine?
I just installed catless downpipes on my 2016 non comp M3 and getting this steady ringing/whine coming from the area near the downpipes. Is this a normal sound going catless or is this a leak? Charge pipes and air intake clamps are all on snug. Only other mod are vrsf charge pipes
Here’s a video of what I’m hearing, sound is most noticeable from beginning of video to 14 seconds: https://youtu.be/NtxnfBVoaTs Last edited by Carrera16M3; 10-22-2020 at 12:14 AM.. |
