Speaking first hand here, those big 6's are TORQUE monsters!
You won't be dissappointed and IMO it would be easier to build/maintain thean the Turbo option.
Ofcourse, you don't get the cool "swoosh" sound, but the music that the 6's produce with an exhaust, is enough to make you forget about the "swoosh".
