My reasearch, tells me that most Stang enthuasists don't like flowmaser for one reason, it does not produce the attack sound tune. The attack sound tune is loud, and it has an attribute that allows for racers (long track) to note RPM range and shift without checking the speedo. Good thing. The Flowmaster is also racing equipment, and meets track demands for decibel restrictions. Problem is that when you step up into the 40 series the quiet approach is out the window unless you know the rpm ranges to quiet them down. Bottom line is that they are loud and produce sound volume above the 70kz (mid to high range) range. That means that if you heard a GT-500 they are tuned to sound off below that range (like bass).
I don't understand flows well enough but they tend to quiet down when extreme pressure is place on them they quiet down, dang near like no cats or exhaust systems are installed; really quiet. Guess they are more about power than sound, sometimes its about engine performance (hint).
Still, on highway speeds they are loud (fluid). Step on the gas and its the loudest thing out there (the growl loudly). Other muffler systems seem to be quiet in comparison. I always get followed and checked out while on the highway by well meaning travellers. I love the attention. Really, the 97 GT gets the attention.
Only you folks know the hard work that goes into achieving those results. Good luck.
Long readin. Feels like a english 101 class in college.
