Muffler replacement cost

The average muffler replacement costs $1,138 – $1,190 at a repair shop, before taxes and fees. Parts run about $1,034 – $1,037 and labor about $104 – $153. That average uses factory parts. Independent exhaust shops with aftermarket mufflers often charge much less, so get a quote from one.

Cost by vehicle

RepairPal estimates for recent model years; your year, engine and trim can change the price.

What the job involves

The muffler quiets exhaust noise. On many cars it is welded or clamped into the rear section of the exhaust; some factory mufflers come only as part of a larger section with pipes, which raises the price.

Warning signs

• Exhaust suddenly louder
• Rattling under the car
• Rust holes or a hanging muffler
• Exhaust smell in the cabin (get this checked right away)

What changes the price

• Your vehicle. Parts for trucks, European and luxury models usually cost more, and on some engines the mechanic has to remove other parts first, which adds labor hours.
• Where you go. Dealers often charge 25% or more above independent shops. Most shops bill about $120 to $159 an hour (AAA, citing a 2025 PartsTech survey).
• The parts. OEM (factory) parts cost more than aftermarket or remanufactured parts. Ask which ones the estimate uses and what warranty comes with them.
• Extras. Related parts found during the job, fluids, shop supply fees and sales tax are not included in these averages.

How to pay less

• Independent muffler shops can often weld in an aftermarket muffler for much less than a dealer.
• Make sure no exhaust is leaking near the cabin; carbon monoxide is dangerous.

How to get a fair estimate

• Ask for a written estimate that lists parts, labor hours and the shop’s hourly rate before any work starts.
• Ask whether the quote uses OEM, aftermarket or remanufactured parts, and what warranty comes with the parts and the labor.
• Get a second quote for any repair over a few hundred dollars. Independent shops often charge less per hour than dealers.
• Ask the shop to show you the old part or the reading that proves it failed, and to call you before doing extra work.
• Check for recalls and warranty coverage first: many powertrain, emissions and hybrid parts carry longer factory warranties.
