    Default Supermegs vs. Thunderheader

    I have an '09 96" HD Road Glide. Its stock except for a K&N high flow breather and a 2-1 Thunderheader. This winter I will be installing a 2-1 Supermegs. I've read that 16 disks with a closed cap will flow approx. 210 CFM. My question is, does anyone know what the CFM numbers are for a Thunderheader? I'm just curious, I'm sure my bike will run better with the SuperTrapp as it most likely will produce more back pressure.

    Thanks.

    You may want to ask the folks at Thunderheader.

    Ok thanks.

    With my above setup, is 16-18 disks with a closed end cap correct?

    Yes, our testing and customer feedback indicates 16-18 discs should provide you with the best usable power.
