Adding a 1979-1993 Mustang cat back exhaust system to your Fox Body can improve performance, sound, and looks. These 2.5" and 3" catbacks from Flowmaster, Bassani, Pypes, Magnaflow, Mac, and SLP are one of the most popular modifications among 5.0 Mustang enthusiasts. Don't like the look of pipes under your bumper? Choose one of our dumped exhaust systems which turns down right after the mufflers giving you a louder exhaust and cleaner rear end looks. Pick up the hardware and hangers you need to finish off the install at Late Model Restoration.
