29399, Exhaust manifold questions
Posted by Joshua97478, Aug-19-02 09:49 AM
What is the diameter of the exhaust pipes coming of the cylinder head? The actual term for them seems to escape me. I want to say primaries, but that doesn't seem right. Oh well, you know what i mean... TIA.

Yes, the diameter of the 4 ehaust primaries of the exhaust manifold? Anyone know? A good guess would help. I don't feel like ripping off my heat shield to measure.

They're not round, they're rectangular with rounded corners. Diameter measurements won't get you anywhere.

Want a width+height measurement? I can get you one tonite when I go home.

The downpipe (the other end of the exhaust mani) is round tho, that might be more accurate.

~2" wide and 1 3/8" tall.

I had one right next to me :)
