How much to replace an exhaust?
Generally, you’re looking at a few hundred dollars for a simple muffler replacement, up to several thousand dollars for catalytic converters or a full exhaust system replacement.
The exact price depends on your car’s make and model, the parts you choose, and labor rates in your area. This article explains typical ranges and factors to consider so you can budget and shop smart.
Common replacement options and price ranges
Here are common exhaust replacement options you might encounter at a shop, with typical installed price ranges to give you a sense of cost.
- Muffler replacement: Typical installed price ranges from about $150 to $350 for a basic muffler; higher-end or stainless steel options can push to $350–$600.
- Exhaust pipe replacement: Roughly $100 to $350 for a simple pipe segment, with labor; longer runs or complex routing can increase costs.
- Catalytic converter replacement: Often the most expensive single component, typically $600 to $2,000+ for parts and $200–$600 for labor; two converters or high-demand models can raise the total further.
- Cat-back exhaust replacement: Parts typically $300–$1,200, labor $200–$600, total commonly $500–$1,800.
- Full exhaust system replacement: When replacing from the header or engine side through the tailpipe, parts $500–$2,500+ and labor $300–$1,000+, for typical cars often $800–$3,500 or more in total.
Prices vary by vehicle and region; always request detailed quotes that break down parts and labor, and check whether the price includes sensors, gaskets, and mounting hardware.
What influences the cost
- Vehicle make, model, and engine configuration
- Number of catalytic converters and their placement
- Type of exhaust system (mild steel vs. stainless steel; OEM vs. aftermarket)
- Labor rates and shop location
- Job complexity, accessibility, and rust or damage requiring extra welding or hangers
- Emissions testing requirements and warranty implications
Understanding these factors helps you set expectations and compare quotes more effectively.
DIY or professional: what to consider
Replacing an exhaust often requires specialized tools, lifting equipment, and welding for pipes and hangers. Catalytic converter work involves heat, precise fit, and emissions considerations. For safety, reliability, and compliance, most drivers opt for a professional shop, especially for longer or more expensive jobs.
Tips for shopping for quotes
To help you compare estimates, keep these steps in mind before you shop:
- Gather your vehicle information (make, model, year, engine) and note symptoms you’ve observed (noise, leaks, reduced performance).
- Ask for at least three written quotes with itemized parts and labor costs.
- Request clarification on parts quality (OEM vs aftermarket, warranty terms) and what is included (gaskets, sensors, mounting hardware).
- Inquire about lead times, disposal fees, and whether the price covers emissions compliance and any required re-inspection.
Take your time to compare quotes and consider both price and the shop’s reputation, warranty offerings, and experience with your vehicle type.
Summary
Exhaust replacement costs cover a broad spectrum—from a straightforward muffler swap to replacing catalytic converters or the entire system. Expect roughly a few hundred dollars for basic jobs and several thousand for more complex or high-demand parts. Costs hinge on vehicle design, part choices, labor rates, and regional factors. Prioritize getting detailed, itemized quotes and weigh quality, warranties, and service reputation alongside price.
