Welcome back:
If you look at the picture I attached, it shows parts and labor for removing and replacing the intake manifold. The part prices listed are OEM parts so they are more expensive than what can be purchased at a parts store, but it gives you an idea of cost.
Next, the labor is listed in hours. Add the hours together and multiply the shop's labor rate by the hours to determine labor costs.
Now, I am unable to find the pipe listed separately. However, the part should be in the area of $30.00 and you can add an extra thirty minutes to the labor for installing it.
The last thing are the miscellaneous items. You will need to replace the engine coolant, there will be shop supply costs, so suspect an additional $30.00.
Please understand this is an estimate. I have no idea where you are located or the cost of parts in your area. I just hope I'm close enough to be helpful for you.
The picture I attached is right from Alldata, and they are very accurate with this info.
Take care and feel free to let me know if you have other questions.
Take care,
Joe
