Exhaust drone - magnaflow

Does anyone with an aftermarket exhaust experience low-end droning around the 1500-2100 RPM zone on their 535i? I have a pair of magnaflow mufflers installed without the factory resonator "x-pipe" installed on the mid pipe. There is considerable "bass" coming out from inside the cabin in that rpm window. Am I alone with this or should I put the resonator back on? thanks for input in advance.. -oldrandomguy

All aftermarket exhausts have drone...exactly that kind of rpm range that everyone will experience.

Some love the 'head splitting' type of noise ...

Do you know if the resonator i cut out even does anything? Is it worth putting back on?

Some exhaust drone more then others, the resonator should help with the drone.
