Early Exhaust Manifold or Tii Manifold

[gyro411]

My 76- 2002 with California emission setup have a bad exhaust manifold and I now need to replace it. I want to eliminate the Calif emission and get an early manifold or Tii manifold. I've read mixed reviews on the board about both. I've found a new early manifold for about $95.00 and a used Tii manifold for about $200. I'm leaning towards the early manifold, but don't want to make my decision based on price alone. Is it that much of a difference for performance between the two? Really need a little advice here. Thanks!!

my experience and opinion is no, there's not a substantial difference in just a manifold swap...i've owned cars with both and wouldn't know one from the other without looking

nozzles, make sure it isn't from an early (pre-emissions) 1600. Their ports are smaller and that will cause a slight performance loss if you don't radius the manifold ports to match those in the head. To check, use a 2002 exhaust manifold gasket as a template.

FYI, the same applies to intake manifolds.

You sure that you want to eliminate the stock manifold and emissions equipment? I think you may need that when it comes to a smog check.

I don't think that Georgians are subject to the same draconian laws on their 76s as we Californians.

Thanks for the comments! They have been very helpful. I currently live in GA where there are no emission inspection. I've never really been concerned about the emission issue until the manifold blew!

I have a Tii mani I'd sell for $75. Email me if you're interested. John
