Ahh found it.

quote from Rob @ Needswings.

"yes that is a straight dump tube off the manifold, torque is not a problem with them, i was runnign a very similar setup when we went 11.9's @ 119.8mph. actually we ran that with exhaust cutouts in the downpipe but these will flow a little better and also give the ability to drop the entire catback and both downpipes off the car, im guessing around a 100 pounds of weight savings

For a forced induction car the best exhaust is NO exhaust, this is as close as we could get while not burning the car down"
