Triumph TR6 - Exhaust Manifold

I have a 1976 TR6. Are exhaust manifolds exchangable with another year TR6 manifold. I need a manifole and there is a 1974 manifold availiable to purchase.I understand that there are one pipe systems and two pipe systems and that must be compatable.

Hi

If you still have the air injection stuff for pollution or ever had you need a 75 or 76. If you do have the pump now may be the ideal time to get rid of it?

If you don't anything past a 72 will bolt up. Can't think of any problems.

Thanks Bill, The air injection tubes rusted out, so i removed them and the pump etc. I took the manifold to the machine shop to plug the holes, and drill out the one tube that broke in the manifold. It came back and really looks a mess. I found a 74 manifold that i can buy and bolt up without looking that things have been modified. Wish I knew, the manifold that was worked on really looks a mess. I want things to look good under the hood.

Just watch when you torque down and hook up pipes. Castings are what is called green new a little more pliant and then from heating and cooling or time age.

That doesn't harm them actually makes better but they tend to form and harden. So stay a bit light on the torque till you heat up a bit through running. Then retorque. Should be good.

I have a used manifold that has the air injection tubes cut off. The problem, I can't get the bolts for the injection tubes out. I've tried penetrant and torch heat. I managed to break one of the bolts off in the manifold.

I'll have to drill out and re-tap the stuck bolts and plug them if I want to use it. In the end, it will look like crap so I think I'll get a nice used one. I've seen them go fairly cheap on Ebay before.

I have a '75 exhaust manifold sitting around, and would be happy to sell it.

Email me if interested.

Replacing it with a good used manifold is the way to go. I have learned by experience.
