So, you’re wondering, “How much is a cat back exhaust?” Generally, you can expect to spend anywhere from $300 to $1,500 or more for a cat-back exhaust system alone, not including installation. The final price depends on many things, like the brand, materials, and features. This guide will break down the costs and help you figure out the perfect exhaust upgrade for your ride.
Exploring Cat-Back Exhaust Costs
Many car owners look to upgrade their exhaust system to improve sound, performance, or looks. A cat-back exhaust is a popular choice for this. It replaces everything from the catalytic converter back to the tailpipe. This means new piping, a muffler, and a stylish tip.
What Exactly Is a Cat-Back Exhaust?
A cat-back exhaust system is a part of your car’s exhaust. It starts right after the catalytic converter and goes all the way to the back of your car. This includes the muffler, resonator (sometimes), and the exhaust tips. By changing this section, you can often get a better engine sound and a little more power.
Why Upgrade Your Exhaust?
People upgrade their exhaust for several reasons:
- Sound: The stock exhaust on many cars is quiet. An aftermarket system can give you a deeper, sportier sound.
- Performance: Better airflow through the exhaust can mean a slight increase in horsepower and torque.
- Looks: New exhaust tips can make your car look sportier.
- Weight Reduction: Some aftermarket systems are made from lighter materials, which can help with overall vehicle weight.
Pricing Factors for Cat-Back Exhaust Systems
The cat-back exhaust system cost can vary a lot. Here are the main things that affect the price:
Brand Reputation and Quality
Well-known brands often cost more. Companies like Magnaflow, Borla, Corsa, and Flowmaster have a reputation for quality and performance. They use better materials and have advanced designs. Lesser-known brands might offer similar looks for less money, but the sound and durability might not be the same.
Material Matters
The type of metal used for the exhaust system plays a big role in its price and how long it lasts.
- Mild Steel: This is the cheapest option. However, it can rust quickly, especially in wet or salty climates. It’s not a good choice for long-term use.
- Aluminized Steel: This is a step up from mild steel. It has a coating of aluminum that offers better rust resistance. It’s a popular mid-range choice.
- Stainless Steel (304 Grade): This is the most common and highly recommended material for good quality exhaust systems. It’s very strong and resists rust and corrosion extremely well, even in harsh conditions. It will likely last the lifetime of your vehicle.
- Titanium: This is the most expensive material. It’s incredibly lightweight and strong, often used in high-performance racing applications. For most daily drivers, it’s overkill.
System Design and Features
The complexity of the exhaust system also affects the price.
- Muffler Type: Some systems have a straight-through muffler, which is less restrictive and louder. Others have chambered mufflers, which can offer a deeper tone and more scavenging effects for performance.
- Resonators: Resonators help to reduce drone (an annoying humming sound) at certain RPMs. Some systems include them, while others don’t. Systems with more complex designs or specific sound-tuning features can cost more.
- Piping Diameter: Larger diameter pipes can sometimes improve exhaust flow, but it needs to be matched to your engine. Custom-designed piping for optimal flow adds to the cost.
- Exhaust Tips: The style and finish of the exhaust tips can also impact the price. Polished stainless steel, carbon fiber, or black chrome tips will cost more than standard polished steel.
Vehicle Application
The make, model, and year of your car are crucial.
- Common Cars: For popular cars like a Honda Civic or Ford Mustang, there are many aftermarket options readily available, and prices might be more competitive.
- Rarer Cars: If you have a less common or older vehicle, finding a specific cat-back system might be harder, and custom options could be more expensive.
- Emissions Equipment: Vehicles that require more complex exhaust routing due to emissions equipment might have more expensive systems.
Average Cat-Back Exhaust Costs

Frequently Asked Questions (FAQ)
Q1: Will a cat-back exhaust void my car’s warranty?
Generally, no. Replacing an exhaust system is considered an aftermarket modification. However, if the exhaust system itself causes a problem with another component covered by the warranty, the manufacturer might deny coverage for that specific issue. It’s best to check your car’s warranty documentation or ask your dealership.
Q2: Can I install a cat-back exhaust on any car?
While cat-back exhaust systems are available for a wide range of cars, trucks, and SUVs, it’s essential to ensure you’re buying a system specifically designed for your vehicle’s make, model, and year. Universal systems exist but require significant modification for proper fitment.
Q3: Does a cat-back exhaust improve fuel economy?
While some users report minor improvements in fuel economy, it’s usually not significant. The primary benefits of a cat-back exhaust are sound and performance. Any fuel economy gains are typically a byproduct of improved engine breathing.
Q4: What is the difference between a cat-back and a full exhaust system?
A cat-back system starts after the catalytic converter. A full exhaust system typically includes headers and may also include a high-flow catalytic converter, replacing almost the entire original exhaust path from the engine back. Full systems are generally more expensive and can offer greater performance gains.
Q5: How long does a stainless steel cat-back exhaust typically last?
A well-maintained cat-back exhaust system made from quality 304 stainless steel can last the lifetime of the vehicle, often 10-15 years or even longer. Factors like driving in extremely corrosive environments (heavy road salt) can reduce its lifespan, but it’s far more durable than mild steel.
Q6: Can I remove the catalytic converter with a cat-back exhaust?
No, a cat-back exhaust system by definition leaves the catalytic converter in place. Removing or tampering with the catalytic converter is illegal in most regions due to emissions regulations and can lead to severe penalties and failed inspections.
Conclusion
The cat-back exhaust system cost is a worthwhile investment for many car enthusiasts looking to enhance their driving experience.
