Installed the Ford Racing Performance Products exhaust this weekend (49 state legal). Took me 20 minutes in my driveway. All you need is a 15mm deep socket, 13mm socket and a 13mm wrench. Factory style clamps and everything else fit PERFECT! Sound is amazing under acceleration, NO drone at hwy speeds. Perfect craftmanship. Got them through Summit Racing for $480 plus shipping. Before this exhaust i hated the sound of the 3 valve 4.6 but now i actually like it better than my old 90 LX 5.0 with full exhaust!
