The Ultimate Buying Guide: A Purrfect Choice for Your WRX
So, you’re thinking about upgrading your Subaru WRX’s exhaust system? That’s awesome! A cat-back exhaust is a popular choice for WRX owners. It’s a cool way to make your car sound better and even give it a little more pep. Let’s dive into what you need to know to find the perfect one.
What is a Cat-Back Exhaust?
First off, what exactly is a cat-back exhaust? It’s the part of your exhaust system that goes from the catalytic converter (that’s the “cat”) all the way to the back of your car. This is where the cool exhaust tips stick out! Replacing this section is a great way to change the sound and performance without messing with the engine’s emissions control.
Key Features to Look For
When you’re shopping for a cat-back exhaust, keep these things in mind:
- Sound: This is a big one! Do you want a deep rumble, a sporty growl, or something a bit quieter? Different systems sound very different.
- Material: What is it made of? This affects how long it lasts and how it sounds.
- Fitment: Make sure it’s made specifically for your WRX model and year. A good fit means easy installation.
- Ease of Installation: Some are bolt-on, which means you can probably do it yourself. Others might need more work.
- Design: Look at the exhaust tips! Do you like the style?
Important Materials
The material of your cat-back exhaust is super important. It affects durability, sound, and even weight.
- Stainless Steel: This is the most common and a great choice. It’s strong, resists rust, and sounds good. Look for 304 stainless steel – it’s the best quality.
- Titanium: This is lighter and can make a different sound. It’s also more expensive.
A good quality stainless steel exhaust will last a long time and hold up well. Cheaper materials might rust or break faster.
Factors That Improve or Reduce Quality
What makes one cat-back exhaust better than another?
- Brand Reputation: Stick with well-known brands. They usually have good quality control and support.
- Welds: Look for clean, strong welds. Poor welds can lead to leaks and a shorter lifespan.
- Design Engineering: A well-designed system can improve exhaust flow, which might give you a small power boost and a better sound.
- Cheap Materials: Using thin, low-grade metal will make the exhaust less durable and sound worse.
User Experience and Use Cases
Who is a cat-back exhaust for? It’s for anyone who wants to make their WRX sound and feel more exciting!
- Daily Driving: Some systems are designed to be a bit louder but not annoying for everyday commutes.
- Spirited Driving: If you love hitting those backroads or the track, a sportier exhaust can really enhance the driving experience.
- Show Cars: Cool exhaust tips and a unique sound can make your WRX stand out.
Think about how you use your WRX most. This will help you choose the right sound and loudness.
Frequently Asked Questions (FAQ)
Q: Will a cat-back exhaust make my WRX faster?
A: A cat-back exhaust can sometimes give a small increase in horsepower and torque. This happens because it allows exhaust gases to flow out more easily. However, the biggest change you’ll notice is the sound.
Q: Is installing a cat-back exhaust difficult?
A: Many cat-back exhausts are designed to bolt directly onto your existing exhaust hangers. If you’re comfortable with basic tools, you might be able to install it yourself. Some people prefer to have a professional do it.
Q: Will a cat-back exhaust affect my car’s warranty?
A: It’s possible. Some dealerships might say that modifications can void certain parts of your warranty. It’s best to check with your dealer before making any changes.
Q: What is the difference between a muffler delete and a cat-back exhaust?
A: A muffler delete just removes the muffler. A cat-back exhaust replaces everything from the catalytic converter back, usually including a new muffler and pipes.
Q: How loud will a cat-back exhaust be?
A: This varies a lot! Some are moderately louder than stock, while others are very aggressive. Look at product descriptions and listen to sound clips online to get an idea.
Q: Can I pass emissions testing with a cat-back exhaust?
A: Yes, because a cat-back system does not affect the catalytic converter, which is what handles emissions. You should still be able to pass your emissions tests.
Q: What are exhaust tips?
A: Exhaust tips are the visible ends of your exhaust pipes. They come in many different styles and finishes, like polished stainless steel or black chrome.
Q: Is drone a problem with cat-back exhausts?
A: Drone is a low humming sound that can be annoying at certain RPMs. Some exhaust systems are designed to minimize drone, while others might have more of it. Reading reviews can help you find out.
Q: Should I get a single or dual exit exhaust?
A: This is mostly for looks! A dual exit has two tips, one on each side, while a single exit has one. Both can sound and perform great.
Q: Where can I find sound clips of different cat-back exhausts for my WRX?
A: YouTube is a fantastic resource! Many WRX owners post videos showcasing their exhaust systems. Search for your specific WRX year and the brand of exhaust you’re interested in.
