A sharp tick when you start the engine can turn into an exhaust smell and a repair quote you did not expect. Before paying for a manifold, have the shop show you whether it is cracked, leaking at a gasket or loose at broken fasteners.
So exhaust manifold replacement is $1,230 to $1,360 in AutoNation Mobile Service’s published estimate. That includes $990 to $1,050 in replacement parts and $240 to $310 in labor.
I will explain what that estimate covers, why a truck with broken bolts can need a different quote, and what US owners paid. A manifold at the engine is a different job from replacing the muffler farther back.
The Published Replacement Price
AutoNation Mobile Service’s guide gives the following breakdown, checked October 26, 2026. It is one service provider’s general estimate, rather than a price for every make and engine.
The low-end sum is $990 + $240 = $1,230, and the high-end sum is $1,050 + $310 = $1,360.
The provider identifies the vehicle, part choice and additional damaged components as cost factors. Its general range does not identify a specific engine or establish a separate price for each side of a V engine.
Ask your shop to identify the bank or side, part number, included gaskets and hardware, diagnostics, tax and any extra labor. A quote for both banks needs comparing with another two-bank job.
A Manifold, a Gasket and a Broken Bolt Are Different Repairs
The exhaust manifold gathers gas leaving the cylinders and sends it toward the rest of the exhaust. It seals against the cylinder head, with fasteners holding the joint together.
A leak at that joint does not by itself prove the casting is cracked. A gasket fault, a damaged sealing surface or a broken fastener can require different work from replacing a damaged manifold assembly.
For gasket, flex-pipe and other leak repairs, my exhaust leak repair guide covers the wider system. Keep those jobs separate from the manifold replacement estimate here.
If the shop recommends a new manifold, ask to see the damage or test result. Have it explain whether a catalyst is part of that assembly, and whether any oxygen sensor actually needs replacing.
Why Fasteners Change the Job
Petty’s Auto Service in Columbus, Ohio describes warped or corroded studs and bolts as a challenge in manifold work. Its services include gasket replacement and repairing or replacing cracked manifolds.
Access matters too. The repairer has to reach the mounting surface without damaging the cylinder head or nearby components. An estimate written before disassembly should explain how extra fastener work will be authorized.
I would ask which bolts and studs are being renewed and whether the estimate includes an allowance for ones that break during removal. That gives you a clearer comparison than a total labelled only “exhaust tick”.
Ram 5.7 Owners: Check the Bulletin’s Status
Stellantis published bulletin 09-001-24 for cold ticking at the exhaust manifolds on certain 2019 to 2024 Ram 1500 DT pickups with the specified 5.7-liter engines.
Its July 13, 2024 Revision C cancels that bulletin and directs repairers to published service information for diagnosis and repair. I have not used labor times from the superseded version to price this guide.
The document is technical information, not authorization for a free repair. Before approving work, ask a dealer to confirm any applicable warranty or coverage for your VIN and the diagnosed fault.
What US Owners Paid
These CarComplaints accounts span a used manifold, two cracked manifolds and a leak repair. The dates and descriptions matter when comparing them with today’s estimate.
- A North Wilkesboro, North Carolina 2009 Malibu owner paid $150 for a used manifold and $100 to have it fitted, in an account dated September 10, 2012. That is $150 + $100 = $250 for the described repair.
- A Hydesville, California 2004 Titan owner described $1,400 in repairs after both manifolds were found cracked, in an October 20, 2008 complaint. The owner describes replacement parts, not a single gasket job.
- A Boerne, Texas 2016 F-150 owner paid $1,650 for an exhaust-manifold leak repair in June 2023, in a complaint dated October 16, 2023. The owner mentions three bolts being replaced and a later leak; no itemized manifold invoice is given.
The Malibu owner later experienced another cracked manifold. A low used-part bill should be weighed alongside its condition, the labor you would pay again and the warranty on the repair.
Choosing the Part and Setting the Repair Scope
A direct replacement manifold should match the engine, side and emissions application.
If the part incorporates a catalytic converter, make sure the proposed assembly is suitable for the vehicle and where it is registered. An unconnected bare casting is a different purchase from an integrated assembly.
Once the work is complete, the shop should check for leaks and confirm the original noise has gone. Keep the parts and workmanship warranty with the invoice.
Can You Drive With a Manifold Leak?
AutoNation identifies exhaust leaking into the cabin as a risk to passengers. If you notice exhaust inside, stop safely, get out of the vehicle and arrange repair or recovery.
A noise that quiets down as the engine warms still needs diagnosis. Do not use the change in sound as proof that the leak has repaired itself.
Questions About Exhaust Manifold Replacement
Does AutoNation’s price include labor?
Yes. Its published total includes the parts and labor figures shown above. Confirm the scope and any other charges for your vehicle.
Do both exhaust manifolds need replacing together?
The diagnosis should identify which side is damaged. The number of manifolds and required procedure depend on the engine; one leaking side does not itself establish that both need replacing.
Is a cold engine tick always the exhaust manifold?
No. The repairer needs to locate the noise and confirm a leak or failed component before pricing the repair.
Can a manifold leak affect oxygen-sensor readings?
AutoNation explains that extra air entering through a manifold leak can affect oxygen-sensor readings and the engine’s air-fuel mixture.
