How much does it cost to replace the exhaust system on a Subaru?
In most cases, replacing a Subaru exhaust will cost between about $600 and $3,000, depending on scope, parts, and labor. The exact price hinges on the model, whether you replace an axle-back, cat-back, or the full system, and where the work is performed.
Replacing an exhaust is not a one-size-fits-all repair. Subaru models vary from compact Imprezas to family SUVs like the Outback and Forester, and high-performance variants such as the WRX and STI often require different components. The cost picture changes with whether you opt for factory (OEM) parts or aftermarket alternatives, and it shifts with labor rates in your region. This article lays out the main cost drivers, typical price ranges, and practical tips for saving money.
What affects the cost
Several factors determine the total price of an exhaust replacement. Understanding these can help you estimate your bill and compare quotes more accurately:
- Scope of work: axle-back, cat-back, or a full system replacement from the engine side through the tailpipe.
- Parts choice: OEM Subaru parts vs. aftermarket stainless steel or aluminized options; high-performance or proprietary designs tend to cost more.
- Vehicle model and year: WRX/STI models with turbocharged engines or certain trims may require different pipes, headers, or downpipes than standard Impreza or Forester models.
- Labor rates and hours: regional differences in shop labor rates and the time needed to remove and install components can swing the total by hundreds of dollars.
- Condition of surrounding components: rust, damaged hangers, or corroded manifolds can add labor time and parts.
- Catalytic converter status: if a converter needs replacement (often related to theft or failure), costs rise significantly.
- Warranty and service plan: some shops offer warranties on labor or parts, which can affect the long-term value of choosing a particular option.
These factors collectively shape the final cost, and they explain why price quotes can vary widely even for the same model.
In practice, your total will reflect both the parts you choose and the labor required to fit them, with the model-specific nuances playing a large role in the final number.
Typical price ranges for common Subaru exhaust replacements
Below are ballpark ranges you’re likely to encounter for different replacement scenarios. These figures assume standard installations at a typical automotive shop in the United States; actual prices can vary by region and shop.
- Axle-back replacement: approximately $200–$600 for parts, plus $100–$300 in labor, totaling about $300–$900.
- Cat-back replacement: typically $350–$1,000 for parts, with $150–$500 in labor, totaling about $500–$1,500.
- Full exhaust replacement (from cat or downpipe to tailpipe): roughly $900–$3,500 for parts, plus $200–$800 in labor, totaling about $1,100–$4,300.
- Catalytic converter replacement (often required after theft or failure): commonly $1,000–$3,000+ total, depending on converter price and labor; premium OEM converters can push costs higher.
Note that premium or dealership-installed parts can push these numbers toward the upper end, while basic aftermarket parts bought online and installed by a shop may sit toward the lower end.
How to save on Subaru exhaust replacement costs
Customers can usually reduce costs by shopping around, asking for written estimates, and understanding the scope of work. Consider these practical steps:
- Get multiple written quotes from independent shops and dealerships to compare labor rates and parts options.
- Ask for a breakdown of parts and labor separately to understand what you’re paying for.
- Consider aftermarket exhaust options if you’re seeking a balance of price and performance, but verify compatibility with your model and local emissions regulations.
- Inquire about warranties on both parts and labor and whether they cover corrosion or installation issues.
- Check whether theft-deterent converters or specialized parts require a longer lead time or additional labor.
By comparing quotes and clarifying scope, you can often secure a reliable replacement at a fair price without compromising safety or performance.
Summary
Replacing a Subaru exhaust runs a broad price spectrum—from a few hundred dollars for a basic axle-back job to several thousand dollars for a full system or catalytic converter replacement. The model, parts choice (OEM vs aftermarket), and labor costs in your area are the main price drivers. Get multiple estimates, ask for itemized quotes, and consider whether a full system or a simpler replacement best meets your needs and budget. With due diligence, you can restore your Subaru’s exhaust performance and emissions compliance without overpaying.
