    Got a flowmaster 44 installed but I'm getting some serious drone in the lower rpm range. It seems to be more prevalent in the drivers side. Only know this because I let the gf drive and it wasn't as prevalent on the passenger side. Muffler shop looked at it and said this is normal in the flowmasters to have drone. Any other thoughts on this?

    Built for maximum low end torque, tooter II.VII intake manifold spacer, LCE long tube header, Injen long tube intake, 2,900 rpm torque peak.
    I also had harmonic resonance (drone) at 2,000rpm with a Magnaflow, and put the stock muffler back on because I'm always driving at that engine speed. It was worth it to try the muffler just to find out, so now I know. :)
