Motordyne LTB is actually not restrictive at all. It's straight-through design with pipe diameters (1-5/8″ primaries stepped to 1.75″ to the 2.5″ merge collector) larger than the OEM one and can definitely benefit power, while at the same time decreasing EGT. A true "long-tube" header featuring equal "gas flow" length helps the car separate exhaust gas pulses well, thereby making power and better preserving torque. However there will be a whole different circumstances if you put stock catalytic converter back. You will see better boost but loose power and increase exhaust pressure as well as EGT. Moreover, the cat isn't going to last long.
