The Ultimate Buying Guide: A Purrfect Choice for Your WRX
Thinking about upgrading your Subaru WRX’s exhaust? A cat-back exhaust system is a popular choice. It replaces the exhaust pipes from the catalytic converter back to the tailpipe. This can change the sound and maybe even the performance of your car. This guide will help you pick the right one.
Key Features to Look For
When you’re shopping for a cat-back exhaust for your WRX, keep these important features in mind:
- Sound Level: Do you want a mild rumble or a loud roar? Exhaust systems come with different sound profiles. Some are designed to be quiet, while others are made to be heard.
- Material: The material affects durability and sound. Stainless steel is a top choice because it lasts a long time and resists rust.
- Tip Style: The tailpipe tips are what you see. They come in different sizes, shapes, and finishes like polished chrome, black chrome, or carbon fiber.
- Fitment: Make sure the exhaust is made specifically for your WRX model and year. A good fit means easier installation and no annoying rattles.
- Resonator/Muffler Design: Some systems have resonators or mufflers. These help control the exhaust noise. A resonator can make the sound deeper, while a muffler quiets it down.
Important Materials
The materials used in a cat-back exhaust are super important for how it looks, sounds, and how long it lasts.
- 304 Stainless Steel: This is the gold standard. It’s strong, won’t rust easily, and sounds great. It’s a bit more expensive, but it’s worth it for the quality.
- 316 Stainless Steel: This is even better than 304 for rust resistance, especially in salty or humid environments. It’s a premium option.
- Aluminized Steel: This is a less expensive option. It’s coated steel that resists rust better than plain steel. However, it won’t last as long as stainless steel.
- Titanium: This is a very lightweight and strong material. It often gives a unique, high-pitched sound. It’s usually the most expensive choice.
Factors That Improve or Reduce Quality
A few things can make a cat-back exhaust great or not so great.
- Welding Quality: Good welds are strong and neat. Poor welds can leak exhaust or break over time.
- Pipe Diameter: The size of the pipes can affect performance. Larger pipes might help with airflow, but if they’re too big, they can hurt low-end power.
- Design and Engineering: A well-designed system will fit perfectly and produce the sound you want. Companies that spend time on research and development usually make better products.
- Brand Reputation: Some brands are known for making high-quality parts. Reading reviews and checking out what other WRX owners use can be helpful.
User Experience and Use Cases
What’s it like to live with a new cat-back exhaust?
- Daily Driving: For everyday use, you might want a system that isn’t too loud. A mild, sporty sound can be enjoyable without being annoying in traffic.
- Spirited Driving/Track Use: If you like to push your WRX hard on twisty roads or at the track, a louder system might be what you’re looking for. It can make the car feel more exciting.
- Aesthetics: The tailpipe tips are a big part of how your WRX looks. A sleek tip can really change the rear end of your car.
- Ease of Installation: Some systems are bolt-on and straightforward. Others might need custom hangers or modifications.
Frequently Asked Questions (FAQ)
Q: Will a cat-back exhaust improve my WRX’s horsepower?
A: Sometimes. A cat-back exhaust can slightly improve horsepower and torque by allowing the engine to breathe better. However, the biggest gains usually come from a full turbo-back system or other engine modifications.
Q: Is a cat-back exhaust legal?
A: In most places, yes. A cat-back system doesn’t remove or change the catalytic converter, which is what makes it legal. Always check your local laws, though.
Q: How difficult is it to install a cat-back exhaust?
A: For most WRX owners, it’s a moderate job. If you’re comfortable working on your car, you can probably do it yourself. Otherwise, a mechanic can install it quickly.
Q: What is the typical cost of a cat-back exhaust for a WRX?
A: Prices can vary widely, but you can expect to spend anywhere from $500 to $1,500 or more, depending on the brand and materials.
Q: Will a cat-back exhaust void my WRX’s warranty?
A: Generally, no. As long as the exhaust system doesn’t cause any damage to other parts of the car, it shouldn’t void your warranty. However, it’s always a good idea to check your warranty terms.
Q: How much louder will my WRX be with a cat-back exhaust?
A: This depends on the specific system. Some are designed for a mild increase in volume, while others are much louder. Many systems will offer different options for sound levels.
Q: Can I get drone with a cat-back exhaust?
A: “Drone” is an unwanted, persistent hum at certain RPMs. Some exhaust systems, especially louder ones, can produce drone. Look for systems with good design and mufflers/resonators to minimize this.
Q: What’s the difference between a cat-back and a turbo-back exhaust?
A: A cat-back starts after the catalytic converter. A turbo-back replaces everything from the turbocharger all the way to the tailpipe, including the downpipe and catalytic converter. Turbo-back systems offer bigger performance gains but are often not legal for street use.
Q: How do I choose the right sound for my WRX?
A: Listen to sound clips online! Many manufacturers provide videos of their exhausts on WRXs. Reading reviews from other owners can also give you an idea of the sound quality.
Q: Are there any performance benefits besides sound?
A: Yes, a well-designed cat-back system can improve exhaust flow, which can lead to small gains in horsepower and torque. It can also make the car feel a bit more responsive.
