The results shouldn't be any different than any of the other brand longtube headers! I've seen one dyno so far but it wasn't on a stock GTO.

Like others are saying, unless they have a restrict or design flaw, they should flow around the same as any of the other 1 3/4 LT headers for the GTOs.

The problem is on that 30ish, can't remember exactly now either, the guy had cam/cai and then put headers on, kinda backwards if you want to know the true gains. I've always gone by 10-20rwhp with a tune! I only picked up 11rwhp, but it was cooler weather when I originally dyno before and warmer when I dyno'd with probably by about 30*+, so that may have been a factor but oh well.
