That's correct, the rumble you get from unequal length headers is the sound of inefficiency. It has to do with the exhaust pulses. That is why they make EL headers. The aftermarket UEL headers sometimes have a different size diameter piping which can lead to better flow over the stock headers.

Don't get me wrong, I wouldn't change to EL headers and loose the rumble. I'll be damned if my car sounds like an EVO.
