Exhaust manifold replacement averages $1,514-$1,724 in RepairPal’s national estimate, while exhaust-manifold-gasket replacement averages $417-$596. Both exclude taxes, fees and location adjustments. Your vehicle’s part, access and damaged hardware change the bill. Confirm whether the quote replaces the manifold or only its gasket before comparing the totals.
Start with a written repair scope. A low gasket-only price and a complete replacement price answer different questions, even when both began with the same ticking noise.
How much does exhaust manifold replacement cost?
The RepairPal national estimate lists $1,164-$1,212 in parts and $349-$512 in labor. Its September 3, 2026 update was checked October 2. The listed total is $1,514-$1,724; preserve that published total rather than recalculating it from rounded component ranges.
Exact-year estimates show why your vehicle matters. These are RepairPal page-level estimates, not local quotes. Each excludes taxes and fees, does not account for your location, and may require related repairs.
| Vehicle and named job | Parts, USD | Labor, USD | Published total, USD |
|---|---|---|---|
| 2018 Toyota Corolla, exhaust manifold replacement | $369-$380 | $171-$251 | $540-$630 |
| 2018 Ford F-150, exhaust manifold replacement | $1,055-$1,292 | $488-$716 | $1,543-$2,008 |
Both pages show a September 3, 2026 estimate update. Neither page’s headline specifies engine variant or the number of sides included. Match your VIN, engine and quote quantity before using either as a comparison. The Ford entry does not establish the price of every F-150 engine or of replacing both manifolds.
Do I need a manifold or just an exhaust gasket?
The answer depends on which part failed and whether the manifold can seal correctly after repair. RepairPal maintains a separate gasket-replacement estimate: $417-$596 total, with $41-$45 in parts and $376-$552 in labor, updated September 3, 2026.
Ask the technician to show the defect that justifies the proposed scope. Choose gasket repair when the inspection supports reusing the assembly and restoring the joint. Choose replacement when the assembly’s condition requires a new part. Have the shop explain a change from the first plan before authorizing it.
| Repair proposal | What you should ask to see |
|---|---|
| Gasket only | Evidence of a leaking joint and explanation of manifold reuse |
| Complete manifold | Identified assembly defect and replacement part number |
| Hardware repair | Location and condition of the affected studs or bolts |
| Additional exhaust assembly | Separate reason that component needs replacement |
Why do broken exhaust bolts raise the price?
Removing a broken stud adds work beyond an ordinary replacement. YourMechanic’s manifold guidance says a broken mounting bolt can cause the leak and that its removal can increase labor and the fee. Ask whether the estimate includes extraction or treats it as a possible additional charge.
Agree on a decision point before removal. For example, request a call with the added labor and recovery plan if a fastener breaks or cannot be removed as expected. That protects your budget without pretending the technician can know every fastener’s condition from outside the engine.
Ask whether the initial price includes replacement hardware. Dorman’s manifold product range describes kits supplied with gaskets and hardware, while its 03218 hardware kit is a separate vehicle-specific product. The actual kit contents should decide which parts need their own line on your estimate.
What should be included in an exhaust manifold quote?
A comparable quote identifies the part, the quantity and the conditions that change the total. Use this checklist with each shop rather than comparing two unexplained bottom-line numbers.
| Quote field | What to record |
|---|---|
| Vehicle | VIN, engine and relevant configuration |
| Assembly | Part number, brand and whether a converter is included |
| Quantity | One manifold, specified side, or both sides |
| Included parts | Gaskets, studs, nuts and other listed hardware |
| Base labor | Removal, installation and final leak check |
| Conditional work | Extraction or damaged-thread work and approval rule |
| Payable total | Diagnosis, fees and tax, showing any credit |
Dorman’s catalog separates conventional and integrated manifold categories. Its listed integrated example, 674-854, is labeled a catalytic-converter product for specific applications. Confirm what your part number includes before comparing an assembly quote with a bare manifold price. Part fitment and applicability should be checked for your vehicle.
How do I compare one-side and two-side estimates?
Record the scope first, then compare the additional cost of the second side. Ask for a written base price for the confirmed fault and a separate incremental price for any proposed work on the other side. Ask what inspection result makes the second repair necessary.
- Identify which side leaks and the failed component.
- Record the replacement quantity and part numbers.
- Confirm hardware and any assembly components included.
- Separate mandatory repair from additional recommended work.
- Compare the resulting payable totals and authorization limits.
Use the shop’s actual incremental figure. Doubling a one-side estimate can misstate shared access labor, while multiplying a bare-part price misses installation and hardware work.
Can I drive with an exhaust manifold leak?
RepairPal’s manifold guidance recommends against driving with a known exhaust-manifold leak. Arrange assistance or vehicle transport before continuing. Fel-Pro’s inspection checklist identifies the potential for exhaust gases to enter the passenger compartment; YourMechanic also describes nearby heat damage.
If you smell exhaust in the cabin, stop driving and arrange assistance. Explain the smell when calling. An estimate comparison can wait until you have a safe plan for the vehicle.
Common questions
Is an exhaust manifold the same as an intake manifold?
They are different systems. The exhaust manifold handles gases leaving the engine; confirm the estimate names the exhaust part when that is the diagnosed fault.
Does replacing a manifold automatically include new sensors?
Ask which sensors, if any, need replacement and why. Request those parts as named line items rather than assuming every nearby component must be new.
Can a noise that disappears warm still matter?
Yes. RepairPal’s 2018 F-150 guidance describes gasket-leak ticking that can diminish as the engine warms. Report when the noise occurs so the inspection can address it.
Should I choose headers instead of a repair manifold?
Treat that as a separate decision about modifications. The headers versus exhaust manifold comparison covers that choice; ask for a restoration quote first so the upgrade comparison has a clear baseline.
How do I know the repair worked?
Ask for the final leak-check result. YourMechanic includes checking for exhaust leaks after installation in its described service procedure.
Bottom line: Compare the same part and quantity, choose the repair supported by inspection, and agree on added hardware labor before the job begins.
