Now I know that exhaust, i.e. which is the best blah blah blah, these mufflers suck...those mufflers suck is always a fairly hot topic and people generally have an idea of what they like, and as it's been pointed out before, that since our trucks aren't "high" performance vehicles, that sound is an important factor as well, nobody wants a raspy sounding truck really. (well at least i don't) I was trolling on the internet and found some data pulled from a magazine about different mufflers tested on a single vehicle and the data printed as far as numbers w/in a specified RPM range, for both HP and torque. Keep in mind the test vehicle was a mustang and was not stock, but it goes through different mufflers from open exhaust, to several different brands and gives comparison data, take from it what you will and with a grain of salt, but it might give you some idea of that most of the mufflers seem to be pretty close in overall power/torque gains over open exhaust, the difference being in what rpm ranges they peak, again, all on this test were fairly close
