Pontiac Firebird Exhaust Manifold Flanges, H.O. 3-Hole, Pair

New factory style exhaust manifold flange set for your 64, 65, 66, and 67 Pontiac Engine with Ram Air manifolds. Exact fit for all models that need three bolt flanges on both sides. These are super nice high quality ductile iron construction. Machined to 2.5 inch diameter for a better flow. Sold as a matched pair.

These high quality exhaust manifold flanges are a perfect choice when replacing or repairing the exhaust on your Ram Air Pontiac. These flanges will fit up to a 2-1/2" pipe and will provide a leak free exhaust for years to come.

These are the exhaust pipe to manifold flanges for the 67 ram air exhaust manifolds (these are the big style header type manifolds for the high performance cars). These are also needed for adding 67 ram air manifolds.

These are unique to the ram air manifold only. Both are 3 bolt flanges. This is not a muffler shop item. If you are adding the high performance manifolds to your car you need these to connect the head pipe to the manifold.

1967 was the first year for the ram air or big exhaust manifolds and the only year that used the 3 bolt flanges on both sides for Firebird.
