I don't know if it's the firing order, or what, but FLowmasters always sounded really good to me on the Fox body 5.0 Mustangs that got them from the factory. Those sounded really good. Not on much else, though
fox bodys sound awesome with flowmasters. i never saw one factory equipped though. what year was that. the ones i had all had a Ford turbo style muffler. left and right were different lengths too. was supposed to eliminate drone they said.
