How much does an exhaust manifold replacement cost?

For most vehicles, the total outlay typically ranges from around $300 to $1,900, depending on the car’s design, labor rates, and where you go. This article outlines the main cost drivers, typical price ranges, and practical tips to manage the expense as of 2024–2025.

Replacing an exhaust manifold involves removing the failed unit, replacing gaskets and possibly studs or bolts, and reinstalling the system with new hardware. Costs vary with whether the engine is turbocharged, diesel, or gasoline, the manifold’s accessibility, and whether aftermarket or OEM parts are chosen. The most accurate estimate comes from a local shop after diagnosing the exact symptoms and vehicle configuration.

What determines the price

The cost to replace an exhaust manifold is not a fixed figure. It depends on several factors that affect both parts and labor. Here are the key considerations:

• Vehicle design and engine layout: ease of access and the number of fasteners.


• Manifold type and material: cast iron vs. stainless steel, single outlet vs. dual/turbo manifolds.


• Labor rates and shop location: urban areas or dealership service centers typically charge more per hour.


• Additional parts and services: gaskets, studs, sensors, or downstream component replacements if damaged.


• Turbos and diesel engines: turbo removal or more invasive access increases labor time and complexity.

In some cases, if the manifold has multiple leaks, cracks, or severely corroded bolts, the job can require more time or even engine work, which raises costs substantially.

Typical cost ranges by scenario

Below are practical ranges for common setups to give shoppers a sense of what they might pay. Prices vary by model, region, and shop policies.

Standard passenger car (non-turbo, single manifold)

For many gasoline-powered cars with a simple exhaust path, parts costs are roughly $100–$350. Labor spans about 2–5 hours, depending on access. At typical labor rates of $80–$120 per hour, expect $160–$600 in labor. Combined, a typical total falls in the $260–$950 range.

• Parts: $100–$350


• Labor: 2–5 hours


• Estimated total: Approximately $260–$950

Closing note: This scenario is the most common for older, non-turbo cars or many modern compact cars with straightforward manifolds.

Turbocharged or twin-manifold systems

Vehicles with a turbo or twin-manifold design tend to incur higher costs due to turbo removal and increased labor time. Parts often run $300–$1,000 or more. Labor typically spans 3–7 hours, occasionally longer. Total estimates commonly range from about $700 to $2,500.

• Parts: $300–$1,000+


• Labor: 3–7 hours


• Estimated total: Approximately $700–$2,500

Note: In performance or luxury models, costs can be higher still if specialized fasteners or sensors are involved.

Diesel engines or trucks

Diesel or larger pickup applications can be more invasive to access. Parts typically cost $200–$900, with labor of 3–8 hours. Total often sits in the $900–$3,000 range, depending on the model and how the manifold is mounted.

• Parts: $200–$900


• Labor: 3–8 hours


• Estimated total: Approximately $900–$3,000

Bottom line: Diesel and heavy-duty applications tend to be at the high end of the price spectrum due to size and access challenges.

OEM vs aftermarket parts

Choosing OEM (original equipment manufacturer) parts often ensures fit and warranty alignment but typically costs more than aftermarket alternatives. Aftermarket or remanufactured manifolds can lower upfront costs, but buyers should confirm compatibility and warranty terms before purchase.

• OEM parts: generally more expensive, but guaranteed fit and warranty


• Aftermarket/remanufactured: usually cheaper with variable warranties

Shop around to see if the overall job price includes any required gaskets, bolts, or sensors, and whether a warranty covers the replacement part and labor.

Ways to save money

Before committing to a repair, consider these strategies to keep costs in check without sacrificing safety or reliability:

• Get multiple quotes from independent shops and dealer service centers.


• Ask about remanufactured or aftermarket manifolds and their warranty terms.


• Confirm whether gaskets, studs, and sensors are included in the quoted price.


• Inquire about advance diagnostics to verify that the manifold is the sole problem.


• Schedule the work during off-peak times or look for promotions, coupons, or bundled services.

Staying proactive about diagnostics can prevent paying for unnecessary or duplicate work if the issue turns out to be upstream or downstream of the manifold.

When to replace vs repair

In most cases, mechanics recommend replacement when the manifold is cracked, warped, or the bolts are severely corroded. Some minor cracks can be temporarily repaired, but such fixes may not last. The type of vehicle and warranty status can also influence the decision to replace with OEM or aftermarket parts.

Consult with a trusted mechanic to weigh the reliability, durability, and warranty considerations before proceeding.

Summary

Exhaust manifold replacement costs vary widely but typically fall within a broad spectrum driven by vehicle design and labor costs. For many cars, expect a total in the hundreds to low thousands of dollars; turbo and diesel applications tend to push the price higher, while aftermarket parts can reduce upfront costs with trade-offs on warranties. Thorough quotes and informed choices can help drivers budget effectively and avoid surprise bills.

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. 

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.

Can I drive 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.
