What affects the price
Several factors influence the final bill for muffler work on a Subaru Outback. Here is what to consider when budgeting.
- Part choice: aftermarket vs OEM. Aftermarket parts are usually cheaper, but OEM parts may offer a perfect fit and longer warranty.
- Labor rates: urban shops and dealer service centers typically charge more per hour than independent shops.
- Exhaust condition: extensive rust, corrosion, or damaged hangers can require extra labor and parts.
- Additional components: clamps, gaskets, sensors, or a need to replace sections of pipe can add to the cost.
- Location and taxes: some states assess higher sales tax or environmental disposal fees that affect the total.
Understanding these variables helps you compare quotes more effectively and avoid surprise charges when the job begins.
What to ask your shop
Before approving any work, ask these questions to ensure transparency and get the best value for your Outback.
- Is the price an out-the-door estimate, including parts, labor, and taxes?
- What type of muffler will be installed (brand, model, and if it’s OEM or aftermarket)?
- How long will the work take, and is a loaner or alternative transportation available?
- What warranty covers the muffler and the labor, and for how long?
- Will the quote include a test for exhaust leaks and a final inspection?
Getting these details in writing helps you compare apples to apples across shops.
What to expect during the service
Most muffler replacements follow a straightforward process, though complexity can vary with vehicle condition.
- The technician removes the old muffler and any attached pipes or hangers as needed.
- The new muffler or exhaust section is fitted, with new clamps and hangers as required.
- A leak test or smoke test is performed to ensure a proper seal and connection.
- They’ll inspect nearby components for wear and advise if additional replacements are prudent.
In general, a muffler swap for a Subaru Outback is a relatively quick service, often completed in about 1–2 hours, depending on the vehicle’s condition and parts being installed.

Is it okay to drive with a bad muffler?
You can drive a car with a bad muffler, but it's not recommended due to serious risks like carbon monoxide poisoning from fumes entering the cabin, poor fuel efficiency, and the potential for being ticketed for excessive noise. It is best to get it repaired as soon as possible to prevent further damage and ensure your safety and the safety of others.
Health and safety risks
- Carbon monoxide poisoning: A damaged muffler can allow deadly carbon monoxide fumes to leak into your car's interior, causing headaches, dizziness, nausea, and even loss of consciousness.
- Hearing damage: The loud, excessive noise from a bad muffler can be distracting while driving and potentially cause hearing loss over time.
Performance and cost implications
- Poor fuel efficiency: A damaged muffler can disrupt the proper flow of exhaust gases, leading to backpressure that reduces horsepower and makes your car less fuel-efficient.
- Engine damage: Driving with a severely damaged or blocked exhaust system can cause your engine to run hotter than normal, potentially leading to more costly repairs.
- Fines: Many areas have laws that require a properly functioning muffler to prevent excessive noise, and you could be ticketed for a violation.
Immediate action
- Check for damage: If the muffler is just hanging and dragging, drive slowly and directly to a mechanic. If it's not dragging on the ground, the risks are lower, but you should still avoid driving it for long.
- Don't drive if it's unsafe: Do not drive if the damage is severe or if you suspect any fumes are entering the cabin.
- Consider towing: If the damage is significant, the safest option is to have the car towed to a repair shop instead of risking a breakdown or an accident.
