well now we know a little bit more, looks in line with the dyno graph on their website. as well, looks like a good single option if that is what you want. I would say the dyno reads about 20 HP high on average from other graphs I have seen, as well as all those 330+whp graphs they are pumping out, puts them right in the 315-320 range where they usually are tuned...anyway as long as you are happy with it that's all that matters, it is their y pipe right? I do not see it on the website.
most true cat-back exhausts from what I have seen make between 10-18 whp, Id say its about right.
