ISPKI Posted June 17, 2013 Share Posted June 17, 2013 My brother was up for father's day and he ended up checking out my 77 280z that is currently residing at my father's house. He has done alot of custom work on motorcycles and immediately pointed out the exhaust pipes coming down from the manifold. I havent been able to find any good shots of how the factory setup is supposed to look. My pipes look fine until after the 6-2 flange. There are two pipes for about 8 inches after the flange, then it looks as though they were crushed into half circle (not uniformly btw, one is half circle, the other is crushed to about 25% diameter) and crammed into the larger pipe that goes to the back of the car. He asked if the car fouls plugs and that severely restricted exhaust pipes like that could be causing it. My engine runs very rich and very rough. The plugs have maybe 100 miles on them and are becoming fouled. Attached are the two photos I took, the rust sort of blends the lines together. Just let me know what you guys think. I assumed there would be a Y-pipe similar to how most of the headers are. Quote Link to comment Share on other sites More sharing options...

beermanpete Posted June 18, 2013 Share Posted June 18, 2013 The exhaust I have which I believe to be factory look very similar to yours. Quote Link to comment Share on other sites More sharing options...
IncompetentOne Posted July 10, 2013 Share Posted July 10, 2013 Mine looked like that as well. Really bad welding and had a crushed look to it... I thought maybe it was the previous owner that did it but now I think it may have been stock Quote Link to comment Share on other sites More sharing options...
NewZed Posted July 10, 2013 Share Posted July 10, 2013 Here's a picture of a typical factory stock 280Z head pipe. I have several and they all look like this. Quote Link to comment Share on other sites More sharing options...
