I think for low-end torque, you need a system that's properly sized for low-end torque. That system will usually have some back pressure at higher rpms. Backpressure is never a good thing, it's just that you can't have it properly sized for low-end torque AND high-end power at the same time. I think it's a misnomer to say you need backpressure for low-end torque.
