How much to replace a Subaru exhaust system?
Replacing a Subaru exhaust system typically costs between about $600 and $2,500, depending on whether you replace an axle-back, cat-back, or the full system, plus whether you choose OEM or aftermarket parts and the local labor rate. The exact price for your model and year will hinge on components involved and any related work such as catalytic converter or headers.
What parts you might replace and what drives the price
The cost varies with which portion of the exhaust is being replaced and whether catalytic converters or headers are included. Here are common options and their installed price ranges to help you plan.
- Axle-back exhaust: Replaces the rear section from the mid-pipe or muffler back to the tips. Typically the least expensive option. Installed price range: roughly $600–$1,200 with aftermarket parts; OEM axle-back often $800–$1,400.
- Cat-back exhaust: Replaces from the catalytic converter back to the tips, including the mid-pipe. More costly than axle-back due to longer run and potential mid-pipe work. Installed price range: about $800–$1,900 with aftermarket parts; OEM cat-back commonly $1,000–$2,000.
- Full exhaust system: Involves replacing the entire run—from headers or up-pipes to the tailpipes (turbo models may include downpipes). This is the most expensive option. Installed price range: roughly $1,500–$3,500 with aftermarket parts; OEM full systems can run $1,800–$4,000 or more depending on model and whether headers are included.
- Catalytic converter replacement (if needed): Can dramatically affect price due to catalyst materials and labor. Installed costs often range from $900 to $3,000+, depending on model, OEM vs aftermarket, and local labor rates.
Full-system projects or copper- or stainless-steel aftermarket systems may command higher prices, particularly if specialty installation (such as welding or alignment checks) is required. Prices also shift with region, shop demand, and any emissions-related work.
Cost by Subaru model and configuration
Costs can vary by model and whether the vehicle is turbocharged. Here is a broad, typical range to help you gauge expectations for common Subaru configurations.
- Turbocharged models (WRX/STI): Cat-back installed commonly ranges from $1,000 to $2,000; full system installs, especially when headers or downpipes are included, can run from $2,500 to $5,000 or higher depending on brand and labor.
- Non-turbo models (Outback, Forester, Legacy, Impreza): Cat-back installed typically $800 to $1,500; full system installs usually $1,700 to $3,000, depending on parts and whether OEM or aftermarket components are used.
- OEM versus aftermarket parts: OEM replacements tend to be at the higher end of the price range, while aftermarket systems can be substantially cheaper but vary in sound, performance, and warranty implications.
These ranges reflect typical U.S. market prices as of 2024–2025 and can fluctuate with part availability, regional labor rates, and vehicle age. Always request a detailed written quote that itemizes parts and labor before authorizing work.
Labor time and what to expect during installation
Labor time varies by the portion of the system being replaced and the vehicle’s condition, especially rust on hangers and exhaust hangers. Here are general benchmarks to help you estimate scheduling and costs.
- Axle-back replacement: About 1–3 hours in most shops.
- Cat-back replacement: Typically 2–4 hours, depending on the complexity of the mid-pipe and clamps.
- Full exhaust replacement (including headers or up-pipes on some models): Roughly 3–6 hours, potentially longer if welding or severe corrosion is encountered.
Inventory and shop capabilities can affect time, so a written estimate with a projected timeline is advisable when you sign the work order.
Model-specific considerations and what to ask your shop
Some Subaru models present particular challenges or opportunities in exhaust upgrades. Here are key questions and notes to keep in mind when requesting quotes.
Turbocharged versus non-turbo models
Turbo models (WRX/STI) often involve downpipes, up-pipes, or more complex piping. This can increase both the price and installation time, and may require tuning or emissions considerations if performance parts are installed.
Age and condition of the vehicle
Older Subarus may have rusted fasteners or corroded hangers, which can add time and cost to the job. A shop may need to cut and replace hardware, or use corrosion-resistant fasteners, increasing labor hours.
Getting quotes and saving money without compromising quality
To get a fair price and a durable exhaust install, follow these steps and tips when shopping around for quotes.
- Get multiple written estimates from reputable shops to compare parts and labor. Ask for itemized line items so you can see exactly what you’re paying for.
- Specify OEM vs aftermarket parts up front and ask about the warranty on both parts and labor. Some shops offer warranties on workmanship that can influence your choice.
- Ask whether the quote includes clamps, gaskets, hangers, and any necessary sensors or O2 sensor spacers. Hidden costs can appear if these aren’t included.
- Consider the long-term value: aftermarket systems may improve sound and performance but may affect resale or emissions compliance depending on local laws.
- Check for emissions testing implications if your vehicle is currently registered in a region with strict emissions rules. In some markets, certain exhaust changes may require inspection or re-approval.
By comparing apples to apples and checking shop workmanship, you can secure a price that reflects quality installation and reliable performance for your Subaru.
What to expect during installation: a quick guide
On the day of service, you can expect the technician to inspect the existing exhaust, remove the old parts, and install the new system with appropriate clamps, hangers, and gaskets. For higher-end or more complex jobs, the process may involve welding or alignment checks to ensure proper fit and noise levels. After installation, most shops will perform a test drive and visually inspect for leaks or rattles and provide guidance on break-in durations and maintenance.
Summary
Replacing a Subaru exhaust system is a job with a broad price range that hinges on what you replace (axle-back, cat-back, or full system), whether you use OEM or aftermarket parts, and how complex the vehicle configuration is (turbo vs non-turbo). Expect installed costs from roughly $600 to $2,500 for common replacements, with full systems and turbo models moving higher into the $2,500–$5,000 territory when headers or downpipes are included. Labor time typically spans 1–6 hours depending on the scope. To get the best value, gather multiple quotes, clarify parts and warranty terms, and consider long-term reliability and compliance with local emissions rules.
How much does it cost to replace a full exhaust system?
On average, a complete exhaust system might range from $300 to over $2000. This price range considers various factors like stainless steel construction for durability and improved aesthetics.
Is it expensive to replace an exhaust?
Exhaust repairs are cheaper but may be short-term, while replacements provide a long-lasting solution. Repairs usually fix specific issues like leaks or damaged parts and cost between £100 and £400. Replacements involve swapping larger sections or the entire system, costing £300 to over £1,000.
How much does it cost to replace the exhaust system on a Subaru?
Exhaust System Repairs:
On average, the cost to repair exhaust components on a Subaru can range from $100 to $1,500 or more, including parts and labor.
Is it worth it to replace an exhaust?
- If your priority is sound, weight, or you are building a performance car with matching upgrades and tuning, an exhaust upgrade is often worth it.
- If you expect large power gains on a stock vehicle without tuning or other changes, the upgrade is usually not cost-effective.
