I have a 1969 Pontiac Grand Prix SJ 428 (not HO). I need to know the exhaust outlet (center or rear) of both the left and right side of the engine. I currently have the exhaust dumping out the rear of the manifold on both the drivers side and passenger side. I was told that was not correct. Can you verify the position of the exhaust pipe for me please so I can get on with my restoration. I have an all matching car and I want to have the exhaust done right. I have called Ames and the tech there couldn't help me. I have Googled several sites without any information. If you aren't sure can you guide me to a person who knows please...Thank you, James Coon
