Loss of low end torque with an aftermarket exhaust?

Will I loose some low end torque if I go with a aftermarket exhaust and larger diameter headers? Is a certain amount of back pressure needed for torque?

Allan,

Our experience is no. The 2zz likes to be opened up. Our 4-1 SC headers have added power in NA and SC applications.

What low-end torque would that be, then?
