I picked up the Borla but only after I heard Stillen and Nismo in person. Probably the most aggressive as far as how deep the tone, probably due to how big the muffler is and that there's no resonator on the midpipe. None of these are annoyingly loud. Nismo is slightly louder and deeper than Stillen if you're trying to choose between the two. As far as flow and performance, I've yet to see any of them on a dyno. My money would be on Nismo for gains but on a 3200+ lb car you'd probably never feel the difference.
