What Makes the Ken Block Subaru Exhaust So Legendary?
If you’ve ever watched one of Ken Block’s Gymkhana videos, you know the sound. That raw, aggressive rumble is as iconic as the driving itself. It’s the sound of pure, unfiltered performance. For years, that sound was reserved for custom-built race cars, but the legacy of that performance lives on. The magic behind that legendary exhaust note isn't a secret; it's the result of purposeful engineering, premium materials, and a direct connection to the man himself. It’s a system designed not just to be heard, but to fundamentally change how your Subaru performs and feels from the driver's seat.
The Crawford Performance Connection
So, what’s the story here? The connection isn't just inspired by—it's direct. The Crawford Performance Gymkhana Exhaust is the official exhaust system born from this legacy, engineered to bring that world-famous performance and sound to your own Subaru. This isn't just a replica; it's a high-quality system built to make your car perform better and sound incredible. It was designed to meet the high standards set by Ken Block, giving you a genuine piece of that Gymkhana experience. When you install this exhaust, you're not just adding a part; you're adding a piece of motorsport history.
The Design Behind the Sound
That unforgettable "Gymkhana sound" comes from a very specific design philosophy. It’s all about creating a raw, aggressive, and deep rumble that makes your Subaru sound like the purpose-built machines Ken Block drove. This is achieved through a special high-flow design that removes the restrictions found in standard exhausts. Think of a stock system as having mufflers and resonators that are designed to keep things quiet. The Gymkhana exhaust gets rid of those bottlenecks, letting the engine’s true sound come out. This free-flowing path is the secret to achieving the authentic auditory experience that enthusiasts are looking for.
Built to Last: Materials and Craftsmanship
An exhaust that sounds and performs at this level needs to be tough. These systems are handmade right here in the United States from rugged, rust-resistant 304-grade stainless steel. This material is chosen specifically for its durability and ability to handle the extreme heat and stress of performance driving. The meticulous craftsmanship ensures that every weld is strong and every bend is perfect, creating a system that not only performs flawlessly but is also built to last. This commitment to quality means you’re investing in one of the best performance parts that can withstand tough conditions on the track or trail for years to come.
How It Improves Your Drive
While the sound is what turns heads, the real magic of the Ken Block exhaust is how it transforms your car's performance. It’s not just about being loud; it’s about being smart, efficient, and powerful. This system is engineered to make your Subaru feel more responsive and athletic from the moment you hit the gas. Let's break down exactly what you'll feel from the driver's seat when you make this upgrade.
Real-World Power and Torque Gains
Think of your engine as an athlete. If it can't exhale properly, it can't perform at its peak. A stock exhaust can be restrictive, creating "back pressure" that holds your engine back. The Gymkhana exhaust system is designed to let your engine breathe freely. This reduction in back pressure translates directly into more horsepower and torque—that raw pulling power you feel when you accelerate. You’ll notice a quicker, more responsive throttle, making your car feel more alive and eager to go. It’s one of the most effective performance parts you can install for a tangible difference in power.
The Secret of Equal Length Headers
The iconic "Subaru rumble" comes from unequal length headers. While beloved by many, they aren't the most efficient design for performance. The Ken Block Gymkhana STi famously used equal length headers, which is the secret to its unique, high-pitched race car sound and a key to its power output. By ensuring exhaust gases from each cylinder travel the same distance to the collector, equal length headers create a smoother, more efficient flow. This design choice sacrifices the traditional rumble for a more balanced and powerful engine response, especially at higher RPMs. It's a modification that signals a serious approach to performance, common in many Subaru STI upgrades.
Better Flow, Less Restriction
At its core, performance is about efficiency. The Gymkhana exhaust is engineered with mandrel-bent tubing, which means the pipes maintain a constant diameter through every curve. This eliminates the kinks and restrictive points found in standard, pressure-bent exhausts. The result is a smooth, unobstructed path for exhaust gases to escape. This improved flow doesn't just help the engine make more power; it allows it to run more efficiently across the entire RPM range. To get the absolute most out of this improved flow, pairing the exhaust with professional engine tuning services will recalibrate your car's computer to take full advantage of the new hardware.
Lighter is Faster: The Weight Advantage
Every pound matters, especially when you're pushing your car to its limits. The factory exhaust system is surprisingly heavy, built with thick, dense materials. The Crawford Performance Gymkhana exhaust is constructed from lightweight, high-grade stainless steel, shaving significant weight off your vehicle. This is what we call "weight reduction," and it pays dividends in every aspect of driving. Your car will feel more agile in corners, accelerate more quickly, and even brake more effectively. It’s a simple equation: less weight means the engine and suspension have less work to do. This is a foundational principle for any performance build, especially for nimble platforms like the Subaru WRX.
Hear the Difference: The Signature Sound
Let’s be honest: a huge part of upgrading your exhaust is for the sound. You want your Subaru to sound as good as it feels to drive, and the Gymkhana exhaust system delivers a profile that’s completely unique—it’s aggressive, deep, and instantly recognizable. This isn't just about being loud; it's about creating a refined, race-inspired tone that tells everyone you’re serious about performance. From the moment you turn the key to the second you hit the redline, this exhaust transforms your car's auditory presence. It’s a sound that matches the legendary performance of Ken Block’s own vehicles, turning every drive into an event.
What to Expect on a Cold Start
The first time you fire up your engine with the Gymkhana exhaust, you’ll know you made the right choice. While it's definitely loud on a cold start, the system produces a deep, aggressive rumble that's unlike anything else. This initial roar is purposeful, setting the stage for the power your car is ready to unleash. It’s a bold statement that quickly settles into a powerful idle as the engine warms up. That first wake-up call is part of the experience—a raw, unfiltered sound that connects you directly to the machine and gets your adrenaline pumping before you even pull out of the driveway.
The Unmistakable Subaru Rumble
One of the most distinct characteristics of the Gymkhana exhaust is how it modifies the classic Subaru boxer rumble. Because Ken Block’s Gymkhana 2 STI used equal length headers, this system is designed to replicate that sound, which actually deletes the traditional uneven rumble. Instead, you get a smoother, more exotic, and higher-pitched race car sound. This is a direct result of the exhaust pulses being timed perfectly. It’s a more refined and focused tone that screams performance, moving away from the typical burble and toward the sound of a purpose-built rally car. It’s a signature part of our performance parts philosophy—sound engineered for power.
How It Sounds Through the Gears
This is where the Gymkhana exhaust truly comes alive. As you accelerate and move through the gears, the sound builds into a raw, aggressive, and deep roar that will have you searching for the nearest tunnel. The exhaust note is tuned to sound incredible under load, creating a symphony of performance that directly corresponds to your throttle input. It helps your Subaru sound just like the cars Ken Block drove in his famous Gymkhana videos. Whether you’re driving a Subaru WRX or an STI, the sound is addicting, encouraging you to enjoy the full range of your engine’s capabilities.
Get Those Signature Pops and Crackles
What’s a high-performance exhaust without some pops and crackles on deceleration? The Gymkhana system delivers those satisfying sounds that make every downshift more exciting. As one owner put it, the exhaust "pops nicely" once it's warmed up. These pops and gurgles are the sound of unburnt fuel igniting in the exhaust pipe, a hallmark of a free-flowing system that’s working efficiently. It’s the car talking back to you, adding a layer of drama and excitement to your drive. This auditory feedback makes the driving experience more engaging and is a constant reminder of the performance lurking under your right foot.
Your Installation and Compatibility Guide
So, you’re ready to bring that legendary sound to your own Subaru. That’s awesome. Getting the exhaust installed is a pretty straightforward process, but it’s always smart to know what you’re getting into before you start wrenching. Let’s walk through compatibility, the tools you’ll need, and a few key tips to make sure everything goes smoothly.

The process mainly involves removing the two 14mm bolts holding your factory muffler in place. If you’re a visual learner, our installation video is a great resource that shows you exactly how to do it, step by step.
DIY or Call a Pro?
This is a classic question for any car modification. The Crawford Gymkhana Exhaust is a "bolt-on" system, which means it uses your car's factory mounting points without any need for cutting or welding. This design makes it a great project for DIY enthusiasts who are comfortable working on their cars. However, there’s absolutely no shame in calling a professional. If you’d rather have an expert handle it, a trusted mechanic can get it done quickly. The most important thing is that the job is done right and you feel confident with the result.
Installation Tips to Know Before You Start
Here’s one crucial tip you can’t skip: after installing the exhaust, you need to get a professional engine tune. This isn’t just a suggestion—it’s essential for your engine’s health and performance.

Putting It to the Test: The Data
It’s one thing to talk about design and materials, but it’s another to see how an exhaust system actually performs. The numbers and the real-world feel are what truly matter when you’re investing in an upgrade for your Subaru. This isn't just about making your car louder; it's about unlocking measurable improvements in power, response, and even engine health. We're talking about the kind of data that shows up on a dynamometer and the feedback you get through the steering wheel and the seat of your pants.
So, let's get into the specifics. We’ll look at what the dyno charts reveal about horsepower and torque, and then translate that into how your car will feel on your daily commute or a weekend track day. We'll also tackle the big question everyone has—the sound—and explore a less obvious but crucial benefit: how this exhaust helps your engine manage heat when you're pushing it hard. This is where the engineering behind the Ken Block exhaust proves its worth with tangible results.
What the Dyno Says
On the dyno, the results are clear. The Gymkhana exhaust system is engineered to help your engine breathe more efficiently by significantly reducing back pressure. Think of it like an athlete taking a deep, clear breath instead of breathing through a straw. This improved airflow allows your engine to produce more horsepower and torque across the powerband. You’ll see gains that aren't just peaks on a chart; they represent a stronger, more capable engine. This translates directly to quicker throttle response and a more eager feel every time you press the accelerator. These are the kind of proven performance parts that deliver on their promise.
How It Feels on the Road
Numbers on a screen are great, but the real magic happens when you’re behind the wheel. The torque gains you see on the dyno translate to a stronger pull when you accelerate from a stoplight or merge onto the highway. That quicker throttle response means the car reacts instantly to your inputs, feeling more connected and agile. It’s a noticeable difference that makes driving more engaging, whether you're navigating city streets or carving up a canyon road. For Subaru WRX upgrades, this enhanced responsiveness is exactly what you’re looking for to make your drive more exciting.
Just How Loud Is It?
Let’s be direct: this exhaust is not for the faint of heart. It’s loud, but it’s a purposeful, well-tuned sound. The Gymkhana exhaust delivers a deep, aggressive rumble that is unmistakably Subaru, just amplified. It avoids the tinny, raspy notes you might find in lower-quality systems. Instead, you get a rich, resonant tone that builds as you climb through the rev range, punctuated by those signature pops and crackles on deceleration. It’s a sound that announces your arrival and turns heads for all the right reasons, giving your car the aggressive soundtrack to match its performance.
Keeping Things Cool Under Pressure
An often-overlooked benefit of a high-flow exhaust system is its impact on engine temperatures. By helping hot exhaust gases exit the engine more quickly, the system reduces heat buildup. This is incredibly important for maintaining consistent performance, especially during demanding situations like track days or spirited driving. A cooler engine is a happier, more reliable engine that can deliver peak power run after run without heat-soaking. This thermal efficiency is a key part of a comprehensive approach to performance, complementing services like our expert engine tuning to ensure your Subaru runs at its best.
How Does It Stack Up?
