Did a muffler delete but now I get too much drone at low RPM
Just installed a new diffuser & decided to do a muffler delete on my 640i. Sounds great but at low RPM I can hear a pretty loud drone inside my car which sucks. Would adding one or two resonators back there help tone down the drone at all? I also have a catted downpipe coming soon as well. any info will help thanks!

Ok it worked! Added only one to the left side and after driving it home after work the drone is very minimal! Woooo!
Praying when I put on the downpipe the drone doesn't come back haha Last edited by PhantomXone; 01-06-2023 at 01:42 PM.. |

Having the same problem after deleting my mufflers. Horrible drone around 2.000 rpm. How is the end result. You stayed with a single resonator or installed a second one after all?

The drone was reduced to a tolerable tone. Still running a single resonator for now & I'm fine with it
