This set consists of one tail pipe hanger and one muffler hanger, both were mounted on the passenger side of the car. The only cars eligible for single exhaust in 1968 were the C code 289 2V and the F code 302 2V, single exhaust never came on 1968 big block Cougars.
In some instances 2 barrel cars had special ordered dual exhaust as an option from the factory. Probably the most common occurrence would be those few F code 302-2V engines installed in the ultra rare, ultra cool XR7-G.
*Early production prior to 11-1-1967
