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
