Pn# INL12768 - 1968-74 Pontiac GTO, Lemans, Tempest, D-Port Ram Air III & H. Cast Iron Exhaust - Factory Correct - 2pc. These are the Pontiac High Performance Cast Iron Exhaust Manifolds for all D-port or Ram Air III heads.
You can upgrade your standard GTO or Firebird to gain performance with these factory style cast iron headers. Made exact to factory originals, with part numbers to stock with 2 1/4 outlet. So you can put a stock 2 1/4" exhaust or there is enough room on the flare of the manifold to fit a 2 1/2" head pipe onto this manifold. 1968-72 LH used 2 Bolt Flange & RH used 3 bolt flange.
These will bolt up to all 68-73 GTO heads and all 68-78 Firebird Heads but require different or Ram Air head exhaust pipe or modification. This is the highest quality exhaust manifold on the market.
Note: 1972 GTO heads are cast without bosses for the end manifold bolts. These are cast off 69 D-port, RA with 69 part #'s 1969 is the peak year for performance with the most support on the manifold that is why they are made off that year - so these will exactly match a 1969 GTO exhaust manifold. The 68 have a heat choke and the 70-72 have the weaker 3 bolt manifold and these are not offered from the factory on 73-up GTO.Others on the market are made off the 73-74 Super Duty Firebird that are much different from the GTO. And cause problems with heat shrouds fitting. These require the cast iron 2/3 bolt exhaust flanges that go on the head pipes.
These are the best on the market and have been tested on cars for over 20 years with no cracks. There is no such thing as a good original the technology from 1969 was not that good resulting in many cracked manifolds. I have never seen an uncracked set come off a car with over 70k miles. These are the details that separate the first place cars from the rest.We have the highest quality parts in the market place period. When only the best will do...
