    LOS ANGELES - Flowmaster's new American Thunder 2.5-inch-inch mandrel-bent header-back performance exhaust system for 1967-70 Ford Mustangs has been engineered for V-8 models with the rear valance cutouts. Because of differences in Mustang chassis design, this kit is not currently engineered to fit the convertible or models with staggered shocks. This dual exhaust system is refined for easy fitment and installs cleanly under the vehicle, with no "hang-down" seen from other aftermarket systems. The Flowmaster kit includes a welded H-pipe assembly, our new high performance 4x9.5 Super 44 Series mufflers, tailpipes, clamps/hardware, and all necessary hangers. The tail pipes exit through the rear valance cutouts with this system and are finished off with a pair of 13-inch long, rolled edge and embossed stainless tips.
