Donny's car is a 68. The exhaust is basically the same. All exhaust manifolds exit at the same place. The L72 tail pipes are easy to make and exit the same as a 327 without resonators. They were 2 1/4 inch with the tails being 2 1/2.The pipe curves to the outside and a hanger supports it from the frame. The pipe then curves back at an angle to exit behind the wheel. My pipes were cut at a slant on the bottom. They stuck out past the quarter panel, and were easily seen. The long pipes extended to the rear of the car and exited under the side of the rear quarter.
