wow seriously this can be seen from so many different ways, but engineering, flow patterns, CNC, they all own us.

people looking for high end, high RPM, top end performance will more than likely choose an equal or as close to equal length manifold as possible, reaon is due to the availability to use a collector, or merge collector. this helps by effectively utilizing each cylinder pulse in a good manner and making them meet in the same place in the same way everytime. some of the cheaper EL manifolds use crappy collectors, or poor designs so not the same effects are seen accross the board. MORE importantly, your car will spool a tad slower with your standard EL mani, but will make up for it on top end. BUT your car should be prepared for it. kits like FULL RACE are designed to be used with certain turbos, downpipes, intercoolers, and piping sizes. take a factor fom the equation and you may end up with different results.

now a shorty, log, cast manifold will give you great spool up times, they are cost effective, and dont seem to crack as often. but you will run into turbine flow choke due to thier poor design, use of materials, inner finishes and such.
