1968 GTO
The 1968 GTO has the distinction of introducing probably the most unique of any GM Muscle Car exhaust systems. The 68 GTO was available with four different systems. The Std duty manual cars recieved 2" head pipes and 2 1/4" tail pipes, while the HO manual cars were outfitted with 2 1/4" head pipes and 2 1/4" tail pipes. The automatic cars used the same head pipes as the manual cars but a tail pipe that probably would get most employees fired if they pitched it to R&D today. This tail pipe was a 2 1/4 tail pipe that split into two 2" pipes one allowing the gases to exit out the back of the car the other pinched shut just above it. Our 1968 GTO exhaust systems come with the correct head pipes, correct unequal length mufflers, correct tail pipes, yes even the tuner tail pipe for the automatic cars, correct hangers, correct GM style clamps, correct flanges, installation instructions, diagrams and sealant, chrome extension which made use of a GM adapter pipe to correct the geometries of the system are an option, as well as a concours show pkg. to keep the system looking clean and new. |
