M340i resonator/muffler delete without drone?
Featured on BIMMERPOST.com Also am I to understand that with a muffler delete the valves are left constantly open? I saw this video about a muffler bypass, and the guys comment about having two cut out valves before the muffler, and didn't quite understand it. Does anyone know what he's refering to and how it compares to simply cutting the muffler out? https://ibb.co/jVz6Kfk On a final note, I wonder why an aftermarket muffler hasn't been made. Eg one that looks the same size/shape as current one so as to not raise suspicion or affect layout/arrangement too much, but with major sound deadening elements etc taken out from inside it. Either way, all help appreciated. Last edited by NIB_; 05-15-2022 at 07:03 AM.. |

It are 2 electronic valves that are welded right before the muffler.
I open/close them with a remote. No drone and it sounds louder and deeper but it stil has the exhaust note too. Last edited by Rednose_M340i; 05-18-2022 at 03:14 PM.. |
