That doesn't mean outliers don't exist though.
Maybe some hypothesis.and interval testing is in order here.
if i could get you guys to visit this thread and give me some data, that would make me a happy guy

I'm ditching my Magnaflow for a Spintech here soon. I'll post results. However I'm neglecting to mention that at the same time, I'll be replacing manifolds with headers, factory y-pipe with one I'm building, 3.5 inch exhaust instead of stock, and a 4" tailpipe. That should shut up the naysayers! Spintech>Magnaflow by at least 40 rear wheel horsepower I'd say.
