Factors to Consider When Choosing the Best WRX Exhaust Systems
Before we jump into specific brands and models, it's essential to consider the factors that matter most to you. After all, the "best" exhaust system is subjective and depends on your priorities.
Sound
Perhaps the most significant factor for many WRX owners is the sound of the exhaust. Do you crave a deep, aggressive rumble, a refined growl, or a more subtle sporty tone? Exhaust sound is determined by several elements, including piping diameter, muffler design, and the resonator.
Larger diameter piping generally results in a louder, more aggressive sound. Straight-through mufflers provide a louder, more aggressive sound, while chambered mufflers generally offer a quieter, more refined sound. Lastly, a resonator helps to tune the exhaust note and reduce drone. Removing or replacing the resonator can increase the volume.
Performance
While sound often takes center stage, don't underestimate the performance benefits of a good cat-back exhaust. This is especially true when you pair a new exhaust with other performance modifications, like a downpipe or tune.
Upgrading your exhaust can lead to increased horsepower and torque. A quality stainless steel piping will reduce back pressure and allow your engine to "breathe" more efficiently, potentially boosting power. Additionally, a freer-flowing exhaust system can make your engine feel more responsive to throttle inputs, improving throttle response.
Lastly, aftermarket exhaust systems are often lighter than stock options, potentially improving handling and acceleration. For the highest quality stainless steel piping that reduces the overall weight, titanium cat-back exhausts are the way to go.
Material and Durability
Exhaust systems are subjected to harsh conditions, from heat and moisture to road debris and impacts. Choose a system made from durable materials that can withstand the test of time.
Common exhaust materials include stainless steel, titanium, and aluminized steel. Stainless steel offers a good balance of durability, corrosion resistance, and affordability. The most common type is 304 stainless steel. Titanium is the gold standard for high-performance exhausts and is known for its strength-to-weight ratio but often comes with a premium price tag.
Aluminized steel is the most affordable material but is less resistant to corrosion than stainless steel or titanium.
Fitment and Installation
Look for a vehicle specific exhaust system designed for your WRX's year and model for the best fitment. Consider your DIY skills; some exhausts may require professional installation.

What exhaust gives the WRX the best sound?
Sound is subjective, but many WRX owners love the aggressive rumble of Invidia or MBRP exhaust systems. For a more refined growl, AWE Tuning is a popular choice. Ultimately, the sound of your WRX's exhaust will depend on the piping diameter, muffler design, and resonator.
What exhaust adds the most HP to a WRX?
An exhaust alone won't dramatically boost horsepower. However, pairing a high-flow catback exhaust system from Cobb, Invidia, or AWE with a downpipe and a tune can optimize power gains. These power gains can be maximized by opting for a steel cat-back exhaust, or even better, a titanium cat-back exhaust.
Who makes the best overall exhaust systems for a WRX?
There's no single "best," but Cobb, AWE, and Invidia are consistently praised for quality and performance. Ultimately, your ideal brand depends on your budget and what you're seeking in sound and performance gains.
What are the best mods for a WRX?
Besides an exhaust, common and effective mods include a cold air intake, downpipe, a tune, and suspension upgrades. However, prioritizing an exhaust to pair with a downpipe is usually recommended.
Finding the best WRX exhaust systems for you involves considering factors like your desired sound, performance goals, budget, and installation comfort. Whether you prioritize a deep rumble or subtle growl, maximizing power gains, or finding that sweet spot between performance and refinement, there's an ideal WRX exhaust system out there. Remember, the most crucial step is researching options thoroughly to find a system that complements your WRX and driving style.
