2007 Subaru Impreza WRX Exhaust Upgrade Guide
Hey guys! Are you looking to boost the performance and sound of your 2007 Subaru Impreza WRX? Upgrading your exhaust system is one of the most effective ways to do it. Let's dive into everything you need to know about choosing and installing the perfect exhaust for your ride.
Why Upgrade Your 2007 WRX Exhaust?
So, why should you even bother upgrading your 2007 WRX exhaust? There are several compelling reasons. First off, the stock exhaust systems are often designed with cost and noise reduction in mind, which means they can be quite restrictive. By installing an aftermarket exhaust, you're essentially freeing up your engine to breathe better. This leads to noticeable gains in horsepower and torque. Who doesn't want more power, right?
Secondly, upgrading your exhaust changes the sound of your car. The stock exhaust is usually pretty tame. An aftermarket exhaust can give your WRX that aggressive, throaty rumble that makes driving so much more enjoyable. Imagine cruising down the street, turning heads with that distinctive Subaru sound. It’s an experience!
Finally, a new exhaust system can improve the overall look of your car. Many aftermarket options come with polished stainless steel tips or unique designs that add a touch of style to your vehicle's rear end. It’s a small detail that can make a big difference in how your car presents itself. In short, upgrading your exhaust is about performance, sound, and style – a triple win for any car enthusiast.
Types of Exhaust Systems for Your 2007 WRX
Okay, so you’re sold on the idea of upgrading, but what types of exhaust systems are available for your 2007 WRX? Let's break down the most common options:
Cat-Back Exhaust Systems
A cat-back system replaces everything from the catalytic converter to the exhaust tips. This is a popular choice because it offers a good balance of performance gains, sound improvement, and ease of installation. You're not messing with the catalytic converter, so you don't have to worry about emissions issues in most areas. Plus, it's generally more affordable than a full turbo-back system. Think of it as a solid all-around upgrade that gives you a noticeable improvement without breaking the bank.
Turbo-Back Exhaust Systems
A turbo-back system replaces the entire exhaust system from the turbocharger all the way to the tips. This includes the downpipe, which is a critical component for improving exhaust flow. Turbo-back systems offer the most significant performance gains because they eliminate the restrictive stock downpipe. However, they can be more expensive and may require professional installation. Also, be aware that replacing the catalytic converter might affect your car's emissions compliance, so check your local regulations before making this upgrade. If you're serious about maximizing performance, this is the way to go, but make sure you're prepared for the extra cost and potential complications.
Axle-Back Exhaust Systems
An axle-back system is the simplest and most budget-friendly option. It only replaces the section of the exhaust system from the rear axle to the exhaust tips. While it won't provide the same performance gains as cat-back or turbo-back systems, it will still improve the sound of your WRX. This is a great choice if you're primarily looking for a better exhaust note and don't want to spend a lot of money. It’s also the easiest to install, often requiring nothing more than basic hand tools.
Considerations for Each Type
When choosing between these options, consider your budget, performance goals, and local emissions regulations. A cat-back system is a good middle ground for most people, while a turbo-back system is for those seeking maximum performance. An axle-back system is perfect for those on a tight budget who still want a better sound. Always do your research and read reviews to find the best system for your needs.
Choosing the Right Exhaust for Your 2007 WRX
Alright, let's get into the nitty-gritty of choosing the right exhaust for your 2007 WRX. With so many options on the market, it can be overwhelming. Here’s what you need to consider:
Sound Level and Tone
Sound is subjective, but it's one of the most important factors for many people. Do you want a deep, rumbling exhaust note, or something louder and more aggressive? Read reviews and listen to sound clips online to get an idea of how different exhausts sound. Keep in mind that what sounds good in a video might sound different in person, so try to find real-world examples if possible. Also, consider your neighbors! A super loud exhaust might not be the best choice if you live in a quiet neighborhood.
Material and Build Quality
Stainless steel is the most common material for aftermarket exhausts due to its durability and resistance to corrosion. Look for systems made from high-quality stainless steel, such as 304 stainless, for longevity. The thickness of the steel and the quality of the welds also matter. A well-built exhaust will last longer and withstand the rigors of daily driving. Don't skimp on quality – a cheap exhaust might save you money upfront, but it could end up costing you more in the long run if it rusts or falls apart.
Performance Gains
Consider what kind of performance gains you're looking for. A turbo-back system will generally offer the most significant improvement, but even a cat-back system can provide a noticeable boost in horsepower and torque. Look for dyno-proven results from reputable manufacturers. Be wary of exaggerated claims – if it sounds too good to be true, it probably is. Also, keep in mind that exhaust upgrades often work best when combined with other performance modifications, such as a cold air intake or a tune.
Brand Reputation
Stick with reputable brands that have a proven track record of producing high-quality exhaust systems. Some popular brands for the WRX include Invidia, Cobb, Borla, and Perrin. Reading reviews and forums can give you a good sense of which brands are well-regarded in the Subaru community. A well-known brand is more likely to offer good customer support and stand behind their products.
Price
Exhaust systems can range in price from a few hundred dollars to over a thousand. Set a budget and stick to it. Remember that you often get what you pay for, but there are also good value options available. Don't be afraid to shop around and compare prices from different vendors. And don't forget to factor in the cost of installation if you're not planning to do it yourself.
Legal Compliance
Make sure the exhaust system you choose is legal in your area. Some states have strict emissions regulations and noise limits. Check your local laws before making a purchase to avoid potential fines or having to swap out your exhaust later.
Installation: DIY or Professional?
Okay, you've picked out your new exhaust – awesome! Now comes the big question: should you install it yourself, or should you pay a professional? Here's a breakdown to help you decide:
DIY Installation
If you're mechanically inclined and have some experience working on cars, you might be able to install the exhaust yourself. An axle-back system is usually the easiest to install, often requiring just basic hand tools and a bit of elbow grease. Cat-back systems are a bit more involved, but still manageable for many DIYers. Turbo-back systems, on the other hand, can be more challenging, especially if you're not familiar with working around the turbocharger.
Before you start, make sure you have all the necessary tools, including a good set of wrenches, sockets, and a torque wrench. Also, it's a good idea to watch some installation videos online to get a better understanding of the process. And remember to disconnect the battery before you start working to avoid any electrical issues.
Professional Installation
If you're not comfortable working on cars, or if you're installing a turbo-back system, it's best to leave it to the professionals. A professional mechanic will have the tools and experience to install the exhaust quickly and correctly. They can also spot any potential issues and address them before they become bigger problems. While it will cost you more upfront, professional installation can save you time and headaches in the long run. Plus, you'll have the peace of mind knowing that the job was done right.
Tools You Might Need
Whether you're doing it yourself or hiring a pro, here's a list of tools that are typically needed for an exhaust install:
- Wrenches and sockets
- Torque wrench
- Penetrating oil
- Jack and jack stands
- Hangers and pliers
- Saw or cutting tool (for removing old exhaust)
Maintaining Your New Exhaust
Congrats, you've got your new exhaust installed! To keep it in tip-top shape, here are some tips for maintaining your new exhaust system:
Regular Inspections
Check your exhaust system regularly for any signs of damage, such as rust, cracks, or leaks. Pay particular attention to the joints and connections. Catching problems early can prevent them from becoming more serious and expensive to repair.
Cleaning
Keep your exhaust tips clean to maintain their appearance. Use a stainless steel cleaner and a soft cloth to remove dirt and grime. Avoid using abrasive cleaners, as they can scratch the finish.
Tightening Connections
Periodically check the exhaust connections to make sure they're tight. Vibration and heat can cause bolts and clamps to loosen over time. Tightening them will prevent leaks and ensure that your exhaust system is performing optimally.
Avoiding Harsh Conditions
Try to avoid driving through deep water or snow, as this can accelerate corrosion. If you do drive in these conditions, rinse off your exhaust system afterward to remove any salt or debris.
Conclusion
Upgrading your 2007 Subaru Impreza WRX exhaust is a fantastic way to improve performance, enhance the sound, and add a touch of style to your ride. Whether you opt for a cat-back, turbo-back, or axle-back system, make sure to do your research, choose a high-quality product, and install it correctly. With the right exhaust, your WRX will not only perform better but also sound amazing. Happy driving!
