These Flowmaster pre-bent tailpipes fit the popular 1963 to 1974 Dodh A-Body cars. 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 offset inlet / offset outlet mufflers and exit straight out the rear, just under the bumper. These tailpipes are a great way to add a factory like fitment tailpipe to a custom exhaust. Backed by Flowmasters three year limited warranty.
