I am getting ready to order my parts from Camelback Toyota for the mini header upgrade since my cast manifold has a crack in it.
The following part numbers are directly from the
Timmy video on the subject, so credit to Jordan for making this list that I simply transcribed, updated, or clarified:
Entry |PN | Desc | Quantity (PN update if needed)

17141-75080 |
manifold | 1
2. |
17173-75020 |
exhaust gasket m engine | 1
3. |

exhaust gasket p | 2
4. |
90116-10149 |
bolt stud | 3
5. |
90179-10070 |

bolt washer base | 2
12.|
90430-24003 |
gasket | 1
There might be more updated PN, I just included the one I remembered to check when I made this table. Also I didn't include the exhaust pipe clamp (PN 90461-32008) because I want to save money, and mine is still working fine and wont cause catastrophic damage if it fails.
The list doesn't include part numbers for the bolts and nuts that hold the heat shield on. I don't have any definitive information on what bolts work.
Another thing about this list is that for items 5, 6 and 8, I designated them with suffix a, b, and c. These designations are not from Toyota, I added them so I can differentiate them without using a part number.
Nut B is what holds the manifold to the engine,
seen at this part of the video. There are 6 of them.
Now that is cleared up, onto my questions... a lot of them have to do with the fact that Toyota doesn't give clear descriptions for what each nut goes to
The first has to do with the different nuts. What does nut A and C fasten to?
Where does item 11 on my list go to?
Do any of these parts change between CA emissions vehicles and 49 state vehicles?
Also I looked into finding the nuts and bolts that hold the new heat shield on. I looked up a diagram on
partsouq for a Tacoma that uses the same exhaust manifold, there are multiple part numbers for these nuts and bolts.
There is 90119-06894 and 90119-06399 for the heat shield bolts, and 90179-06257 for the heat shield nut. All 3 of those part numbers bring up results for engine related diagrams. Does anyone know if they are the correct ones for the heatshield?
