I would like to know as to what is the reason for the high labor charges? Can you please let me know what is involved with replacing the exhaust manifolds on this vehicle?

All the national labor guides show 7.0 hour per side. The manuals all describe that cylinder head removal is required. I have just recently completed a left side manifold replacement on a 4.7 Tundra and there is a way to remove the manifold without removing the cylinder head. It is still quite difficult but can be accomplished in half the time and at a substantial savings over “book time”

I just replaced my left exhaust manifold. Real pain and took about 7-8 hours. I did it without taking the clylinder head off. Two nuts behind the motor mount are almost impossible to get to. Better to jack up the engine (hindsight) and take off the rubber motor mount. The manifold will then come out easily. Can get it out without taking off the motor mount. I didn't figure this out until I was almost done. Could not get any torques wrench on any nut as they are on hard angles to get to. Make sure to put the heat shield on before the motor mount. If motor mount is on, do the lower ones first. Easier to get the upper ones when the lower ones are on. Mine has only 3 bolts and heck with the other one that was impossible to get on. The heat shield is sprung and the holes do not match up. Was it worth saving $1900 Toyota wanted, ask me in a year.

Hello, I purchased some after market manifolds for my tundra. The problem is the heat shields won't bolt up with the new exhaust manifolds. Would you happen to know if I could leave them off? My truck is at a local shop and the shop is very trustworthy and I've never heard a real complaint about the shop. But he is saying that we can probably get away with not having them on. I looked underneath as well and I partially agree with him. Heat shields there for a reason tho. Any suggestions would be great. Thanks in advance, ThatGuy
My labor guide says 7 hours per side which seems high. Alldata is a good information source. Autozone have some popular workshop manuals for free on line once you register (for free) on their website or there is a company that independent auto repair shops "buy" their information from that offer a very reasonable service to do it yourselvers. You can get a one week subscription or year subscription very cheap. The information is year make and model specific repair procedures, service bulletins, component locations, wiring diagrams ect.... great quality information same as the professionals have ,much better than generic workshop manuals from parts stores, much cheaper than the factory manual try
and get an online repair manual subscription.
