Drone Issue with Super Sprint Headers + Magnaflow Muffle
Hi Guys - I need your help, so I recently installed catless headers (Super Sprint) on my E92 325 - along with a rear Magnaflow muffler.
the sound is amazing, but the drone now at around 2K RPM is getting serious.
what are my options? to try and keep the sound note as similar as possible but reduce drone?
would replacing the Magnaflow muffler with active Autowerke Gen 2 rear muffler do the trick? or is there another way to play around with the system to try and minimize the drone?
