A friend of mine called & said he installed 2 Mac Flowpath Mufflers on his 5.4 F150. He tells me it sounded great when he had his 4.6 Stang & now w/the 5.4 it very unique(from all the flowmaster) & sounds even better than when it was in his stang.
Abnybody else put them on or knows of people who have? Does it sound mean?
