Is there a use for a split exhaust manifold? I replaced with a new one... found 2 splits between the exhaust pipe threads and the bend to horizontal. I suspect just the metal scrap box.
Are you talking about a stock manifold with two cracks or a dual outlet speed accessory manifold?
I added the Chaffin split exhaust manifold and the oversize intake manifold years ago. What a difference that made. Zoom...... J.
Unfortunately, a stock, single pipe exhaust that had blown out.
Since these have been reproduced,impractical to weld.Prior to that, all manner of fixes were attempted.
Very good... thanks!
