How much does it cost to replace the exhaust manifold on a Dodge Dakota?
Typically, replacing an exhaust manifold on a Dodge Dakota costs about $300 to $900, depending on engine configuration, parts chosen (OEM vs aftermarket), and local labor rates.
In this article, we break down what drives the price, provide rough ranges for the Dakota’s common engines, outline what the replacement involves, and share tips to help you save money without compromising on quality.
What drives the cost
A variety of factors influence the final bill. The following are the main cost drivers you’re likely to encounter when planning a replacement:
- Engine configuration and number of manifolds: Most Dodge Dakota models use one exhaust manifold per bank, so replacing multiple manifolds or both sides can increase labor time.
- Manifold type: Factory cast-iron manifolds are usually cheaper than aftermarket headers or performance manifolds, but durability and fit can vary.
- Labor rate and time: Shop hourly rates vary by region; more complex access or heavy corrosion can extend the job from a couple of hours to half a day or more.
- Corrosion and accessibility: Rusted bolts, seized studs, or a tight engine bay can add time and potential extra parts (studs, gaskets, heat shields).
- Related components: Gaskets, bolts/studs, oxygen sensors, and occasionally catalytic converter mounting hardware may be replaced during the job, adding to cost.
Understanding these factors helps you get a realistic quote and compare options from different shops.
Typical price ranges by engine configuration
Prices vary by the Dakota’s engine, but these ranges reflect common quotes you may receive in the market. They include parts, labor, and standard shop markup, assuming a standard installation without unusual complications.
- 3.9L V6 and similar smaller engines: commonly around $250–$700 total. This range covers OEM or aftermarket manifolds and typical labor times.
- 4.7L V8 (dual-bank configuration): commonly around $400–$1,000 total. Labor tends to be higher due to the size and access of the V8 layout.
- Other Dakota engines (e.g., 3.7L V6 variants): commonly around $350–$900 total. Variations depend on rust and access in your specific model year.
Prices above are rough benchmarks. Your exact quote can be higher or lower based on local rates, the shop’s familiarity with the Dakota, and whether OEM or aftermarket parts are chosen.
Do-it-yourself vs professional replacement
If you’re mechanically inclined, you can save on labor by supplying parts and doing the work yourself. This reduces costs to roughly the price of the manifold, gaskets, bolts, and any needed consumables. However, a DIY replacement requires appropriate tools, a safe workspace, and time. For most Dakota owners, getting a professional quote ensures proper torque, gasket seal, and exhaust system integrity.
- DIY cost considerations: Parts (manifold, gaskets, bolts) typically $60–$400 depending on OEM vs aftermarket; no labor charges, but you’ll bear all safety and tool costs.
- Professional advantages: Proper torque specifications, rust mitigation, warranty coverage on workmanship, and reduced risk of leaks or exhaust leaks.
Weigh the upfront savings against the potential risks and the time you’re willing to invest when deciding whether to DIY or hire a shop.
What to expect during replacement
During an exhaust manifold replacement, a shop will typically inspect for rusted bolts, check for damaged studs, replace gaskets and hardware, and verify there are no exhaust leaks after reassembly. If a manifold is heavily corroded or a bolt breaks, the job can take longer and cost more due to extra labor or the need for replacement parts.
Cost-saving tips
Consider these strategies to keep costs reasonable without sacrificing reliability:
- Request multiple quotes to compare labor rates and part options (OEM vs aftermarket).
- If you have an older Dakota, ask about a rust-prevention plan or anti-seize recommendations for future maintenance.
- Ask the shop to confirm whether they’ll replace only the manifold or both sides (if applicable), and what is included in the estimate (gaskets, studs, etc.).
- Inquire about bundled pricing if other exhaust work is planned, such as replacing a catalytic converter or oxygen sensors in the same service cycle.
Approaching quotes with these questions can help you avoid surprise additions and lock in a fair price.
Summary
Replacing an exhaust manifold on a Dodge Dakota typically costs between roughly $300 and $900, with higher totals possible for the 4.7L V8 or in cases of heavy rust and added parts. Prices vary by engine configuration, labor rates, and whether OEM or aftermarket parts are used. Getting multiple estimates, understanding what’s included, and deciding between DIY or professional installation are effective ways to manage the cost while ensuring a durable repair.
What causes an exhaust manifold to go bad?
Exhaust Manifold Gasket Failure: Causes and Solutions Exhaust manifold gaskets often fail due to heat warping and gasket material deterioration over time. Exhaust manifold gasket failure typically results from excessive heat causing warping or cracks in the manifold or gasket.
How long does it take to fix an exhaust manifold?
2 to 4 hours
How long does an exhaust manifold repair typically take? Repair time varies based on the damage and your car model. It usually takes 2 to 4 hours.
Is it worth replacing an exhaust manifold?
You should consider replacing your exhaust manifold if you notice loud noises, exhaust smells in the cabin, decreased fuel efficiency, or poor engine performance like rough idling or poor acceleration. These are all symptoms of a leak or crack in the manifold, which can also cause you to fail emissions tests and, in severe cases, poses a carbon monoxide poisoning risk. A replacement can also improve overall performance and efficiency.

When to replace your exhaust manifold
- Loud or unusual noises: A hissing sound or a ticking noise (especially when the engine is cold) can indicate a leak.
- Exhaust smells: The smell of exhaust fumes inside the vehicle is a major red flag for a leak.
- Performance issues: You might experience decreased acceleration, poor fuel efficiency, or the Check Engine light to come on.
- Visible damage: Look for cracks or severe corrosion on the manifold itself.
- Failed emissions tests: A damaged manifold can prevent your vehicle from passing an emissions test.
Risks of not replacing it
- Health risk: A major leak can allow carbon monoxide to enter the vehicle's cabin.
- Engine damage: A severe leak could damage other components near the manifold, such as wiring harnesses or hoses.
- Lower efficiency: A leaky or cracked manifold can negatively impact fuel economy and overall performance.
Can I drive my car with a bad exhaust manifold?
You can likely drive with a minor exhaust manifold leak, but it's highly unadvisable for larger leaks due to the risk of carbon monoxide poisoning and potential damage to your vehicle. Driving with a major leak can cause performance issues, poor fuel economy, and loud noises.
Risks of driving with a bad exhaust manifold
- Carbon monoxide poisoning: This is the most critical risk, as toxic, odorless gases can enter the vehicle cabin and cause serious harm or death.
- Poor performance: The engine may feel less responsive, experience power loss, and accelerate poorly.
- Reduced fuel economy: The engine's performance changes can lead to increased fuel consumption, costing you more money.
- Loud noise: You will likely hear a noticeable ticking, tapping, or hissing sound, especially when the engine is cold.
- Engine damage: A major leak could cause other components, like wiring, to be damaged by the hot exhaust.
- Failed emissions test: A significant leak will almost certainly cause your car to fail an emissions test.
What to do
- For minor leaks: If the problem is small and only causes a ticking noise that disappears when the engine warms up, you may be able to drive for a short period, but avoid long trips or sitting in the car while it's idling.
- For major leaks: Do not drive if you see smoke or smell exhaust fumes in the cabin. It is best to have the vehicle inspected and repaired immediately.
- Get it checked: It is recommended to have any exhaust manifold issues inspected by a professional to determine the severity and get an accurate repair estimate.
