These Flowmaster pre-bent tailpipes fit the popular 1987 to 1996 Ford F-150 trucks. The tailpipes are 2.5-inch, 16-gauge aluminized steel and mandrel bent to allow better flow of the exhaust pulses as they exit the system. These tailpipes are designed to work with dual outlet mufflers and exit on each side of the bed, just after the rear tires. These tailpipes are a great way to add a factory like fitment tailpipe to a custom exhaust. Backed by Flowmaster's three year limited warranty
