Replacing the exhaust manifold on a Jeep Wrangler typically costs between $500 and $1,500, depending on engine type, labor rates, and whether additional parts or related components must be replaced.
What drives the cost
Several factors determine the final price: the engine layout (older inline-6 vs newer V6 or turbocharged engines), whether the manifold is OEM or aftermarket, labor rates in your area, and the ease of access under the vehicle. Additional work such as removing a turbo, replacing oxygen sensors, or addressing rusted studs can push the total higher.
Cost by engine type
The following ranges reflect typical shop prices in the United States as of 2024–2026 for a standard exhaust-manifold replacement, including gaskets and basic hardware. They may not include tax, disposal fees, or towing, and prices vary by location and shop.
- 4.0L Inline-6 (pre-2012 JK models): Parts typically $120–$350; labor $400–$900; total roughly $520–$1,250.
- 3.6L Pentastar V6 (JL/JT era, 2012 onward): Parts typically $150–$700; labor $350–$900; total roughly $500–$1,600.
- 2.0L Turbocharged inline-4 (JL/JT with turbo): The exhaust manifold is often integrated with the turbo; replacement can involve removing the turbo. Parts and labor commonly total about $900–$2,000 or more depending on the extent of work.
Note: These figures are general estimates. Real-world costs can be higher if there are long exhaust downpipes, catalytic converter issues, broken studs, or if the vehicle requires additional repairs to engine or exhaust components.
Other considerations
Warranty status, local labor rates, and the choice between OEM vs aftermarket parts also influence price. OEM parts are typically more expensive but may come with a warranty and precise fit, while aftermarket manifolds can save money but may affect emissions or performance. On turbo models, the job can be more involved and may require turbo removal, which raises labor time and cost.
Getting an estimate
To obtain an accurate quote, contact multiple shops with your Wrangler’s year, model, and engine. Request a written estimate that separates parts, labor, and incidental costs, and ask for both OEM and aftermarket options when available. If you suspect rusted studs or corrosion, mention it upfront so the shop can factor potential extra labor into the quote.
- Provide your Wrangler's exact year and engine (for example, 2018 Wrangler JL with 3.6L or 2020 Wrangler JL with 2.0L turbo).
- Ask for both OEM and aftermarket part options and note any warranty considerations.
- Request a separate line item for related work (downpipes, catalytic converter, oxygen sensors) in case those need attention.
Concluding: Prices can vary widely by region and shop, so getting several quotes helps you determine a fair price and avoid surprises.
Summary
For most Wranglers with non-turbo engines, replacing the exhaust manifold typically falls in the $500–$1,500 range, with turbo-equipped models often higher due to the turbo’s involvement. Always compare multiple written quotes, clarify parts options, and consider potential related repairs when budgeting for this service.
Is it worth fixing an exhaust manifold?
Cracks in the manifold can lead to exhaust leaks, reducing engine efficiency and potentially causing further damage to the engine or exhaust system. Repairing the crack promptly can restore optimal engine performance, improving fuel efficiency and power output.
What is the average lifespan of a Jeep Wrangler engine?
With the right care, Wranglers can easily reach 300,000 miles—and many exceed that. Owners in Spokane and Yakima have reported clocking well past 400,000 miles, particularly with Pentastar V6 engines that have had regular oil changes and timely part replacements.
How many hours does it take to replace an exhaust manifold?
three to five hours
Replacing an exhaust manifold should only take three to five hours of work. Cost for that time runs $339 to $497, on average.
Is it okay to drive with a bad exhaust manifold?
This can be dangerous as it may include carbon monoxide, so it should be addressed immediately. A leaky exhaust manifold can cause a drop in engine performance, such as reduced power, acceleration, and fuel efficiency.
