These Flowmaster pre-bent tailpipe kits fit the popular 1962 to 1974 Dodge/Plymouth B-Body cars (15823) and 1963 to 1974 Dodge/Plymouth A-Body cars (15826). The tailpipes are 3- in. for the 15823 kit and 2.5- in. for the 15826 kit. Both use 16-gauge aluminized steel and are mandrel bent to allow better flow of the exhaust pulses as they exit the system. The tailpipes are designed for these specific chassis 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 Flowmaster’s three year limited warranty.
