How much is a full exhaust change?
A full exhaust change generally costs between about $600 and $4,000, depending on parts and labor, with most common cars landing in the $1,000–$2,500 range. If you include a catalytic converter replacement or opt for premium materials, expect higher prices. This article explains what goes into the price, common configurations, and how to shop for a fair quote.
What a "full exhaust change" includes
Shop terminology can vary, but a true full exhaust change typically means replacing components from the front portion of the system (near the engine) to the tailpipe. Some shops quote a “full” job as cat-back (from the catalytic converter back), while others include the catalytic converter and front pipes in a single replacement. Here’s how the common configurations break down:
- Cat-back replacement (from the catalytic converter back to the tailpipe): This changes the muffler, resonator, and piping, but does not replace the catalytic converter or the front pipe.
- Full system replacement (front-to-back): This includes downpipes, the catalytic converter (or high-flow converter), mid-pipes, resonator, muffler, and tailpipe.
- OEM vs aftermarket parts: OEM replacements replicate factory fit and emissions connections, while aftermarket systems may offer different materials, bends, and performance characteristics.
- Premium or high-performance setups: Includes higher-grade materials (such as stainless steel), mandrel bending, larger-diameter piping, and sometimes tuned exhaust notes—usually at a higher cost.
When budgeting, be aware that some shops will replace only the back half, some will replace the entire system, and others will tailor the quote to your vehicle’s layout. The exact definition of “full” can change from shop to shop.
Typical price ranges and what affects them
Prices vary widely by vehicle and region, but the following ranges reflect common U.S. market estimates for installed work. The figures include both parts and labor, assuming standard labor rates and average vehicle access.
- Cat-back replacement (no catalytic converter): Typically installed price ranges from about $400 to $1,800. Parts alone can be roughly $150–$800 depending on material and brand.
- Full system replacement (front-to-back, including front pipe and catalyst): Installed generally runs about $1,500 to $4,000. Parts can range from $600 to $2,500 based on material and whether a catalytic converter is included or upgraded.
- OEM factory-style replacements vs aftermarket: OEM replacements usually cost between $700 and $2,100 installed, while aftermarket cat-back or full systems run roughly $1,000–$3,000 installed for mid-range parts; premium options can push toward $4,000.
- Premium materials and specialty builds: Systems made from high-grade stainless steel, titanium, or with specialized tuning can range from about $1,800 to $4,500 (or more) installed, depending on the car and scope.
Prices can swing based on the vehicle’s make/model, the shop’s labor rate, and the exact parts chosen. In some cases, particularly on older vehicles with rusted hardware, extra labor may be required to remove stuck bolts or brackets, which can add to the total.
Factors that affect price
Several factors determine the final bill. The following elements often push costs up or down:
- Vehicle make, model, and engine layout (compact cars vs. trucks, and how accessible the exhaust system is).
- Labor rates in your area (urban shops tend to charge more per hour than rural shops).
- Material choice ( aluminized steel vs. stainless steel vs. titanium) and build quality (OEM-mimic vs. high-performance).
- System type (cat-back vs. full front-to-back) and whether a catalytic converter is replaced or upgraded.
- Ease of access and condition of existing components (rusted bolts, heat shields, and prior modifications).
- Regulatory requirements and emissions equipment compatibility (some setups must meet certain emission standards or CARB approvals in certain states).
- Warranties and shop guarantees (some shops offer longer warranties on installations and parts).
To avoid surprises, obtain written quotes that itemize parts and labor, and ask shops to explain what is included in a “full” exhaust change for your specific vehicle.
Regulatory and safety considerations
Modifying or replacing an exhaust can affect emissions controls and vehicle diagnostics. In many jurisdictions, removing or bypassing catalytic converters or oxygen sensors can be illegal or violate emissions regulations. California and other states with strict emissions standards require CARB-compliant components for street use. Additionally, improper installation can lead to exhaust leaks, excessive noise, or unsafe exhaust routing. Always verify that your chosen setup complies with local laws and does not affect warranty requirements.
When in doubt, consult a licensed mechanic or a shop familiar with your vehicle’s emissions system and local regulations, and consider requesting documentation of compliance for your records.
Summary
For most drivers, a full exhaust change costs roughly $1,000 to $2,500 for a typical cat-back or full-system replacement, with many projects landing in that range. If you replace the catalytic converter, upgrade to premium materials, or choose a high-end performance build, prices can jump to $3,000–$4,000 or more. Always clarify with the shop what “full” means in your case, compare quotes from several providers, and ensure the setup complies with local regulations and emissions standards. A well-documented quote and reputable installer can help you balance cost, performance, and legality.
Is it worth getting a full exhaust system?
A full exhaust system is worth it if you prioritize maximum performance gains (horsepower and torque) and a more aggressive sound, but it is a more expensive, complex, and often louder option that typically requires a professional tune for best results. It's a bigger investment compared to a slip-on, and the performance benefits are most significant in high-RPM situations.
Benefits
- Performance: Offers the most significant horsepower and torque increases by improving exhaust flow, especially when paired with an engine tune.
- Weight reduction: Replacing heavy stock components can significantly reduce the overall weight of the vehicle.
- Sound: Creates a more aggressive and desirable exhaust note.
- Aesthetics: Offers a cleaner, more race-inspired look, with many customization options available.
Downsides
- Cost: Full systems are significantly more expensive than slip-on options, often costing over \$1,000.
- Complexity: Installation is more complex, and a professional tune is often necessary to prevent damage and ensure proper performance.
- Noise: It will be louder than a stock system and potentially louder than a slip-on, which can be a drawback for some and may lead to issues with noise regulations on public roads or at racetracks.
- Legality: Often requires removing the catalytic converter to achieve maximum performance, which is not street legal.
- Potential for other issues: Depending on the specific system, you may need to remove parts like the center stand or passenger footpegs.
Is it right for you?
- Get a full system if: Your priority is maximizing performance, you have a larger budget, and you are prepared to get a professional tune and deal with potential noise and legality issues.
- Consider other options if: You are on a tighter budget, primarily want an improved sound and look without a huge performance increase, or if you are a beginner and the complexity of installation is a concern. In this case, a slip-on exhaust with a tune might be a better fit.
How much does it cost to get my exhaust changed?
Exhaust system repairs can vary from quite simple to extensive. Exhaust systems can be made of basic to mid-range and high-performance parts. Given this, you can expect to pay anywhere from $300 - $2000 for a complete replacement.
How much does it cost to replace a whole exhaust?
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.
