That's just one test. Every other test done by every other independent showed the Borla XS makes the most power. Don't believe everything you read just because you see it one time. Borla XS simply flows more, makes more horsepower, and is the quietest. I won't say that it is by some large gulf, because it is usually only 3-4 hp, but at 10 decibels less noise, I will take it.
Not to mention that the Flowtech mufflers always tested among the loudest at idle, loudest at cruise, and loudest at WOT.
If you like your system to be loud at full throttle, that is your own decision; not the way a "muffler should be". I own a Lincoln, not a Fox Mustang. I don't want my engine to make a lot of noise at WOT.
