You love your Subaru WRX STI and whether you drive it on the highway or compete on the racetrack, a popular modification is upgrading your 2015 to 2021 WRX exhaust system. Why? It’s an easy way to enhance your car's roaring sound and improved performance. So what are the different aftermarket Subaru exhaust options that will take your WRX STI to the next level? The experts at JDMuscle have broken it all down for you. Take a look at 5 aftermarket options, each one offering a louder, more enjoyable driving performance and experience.
Cat-Back Exhaust Systems: A Common Upgrade
One of the most popular exhaust upgrades is the cat-back exhaust system. This simple aftermarket upgrade will improve your horsepower, fuel efficiency, and give you an aggressive, roaring sound. Everyone is sure to hear you coming and going! This system replaces the exhaust components from the catalytic converter all-the-way back to the exhaust tips. Plus, a cat-back provides noticeable performance improvements without extensive and costly changes.
Turbo-Back Exhaust Systems: Get Maximum Performance Gains
If you are a Subaru WRX STI owner looking for maximum performance gains, a turbo-bak exhaust upgrade is one to consider. Yes, it is an investment, but if you are looking to significantly reduce back pressure and want your turbocharger to spool up faster, this is an option for you. This upgrade replaces the entire exhaust system all the way from the turbo-charger to the exhaust tip, down-pipes, and mid-pipe. Remember that a turbo-back exhaust system may require other modifications, like tuning your engine management system to prevent problems down the road. If you own a newer model like the 2021 WRX exhaust, make sure it is compatible with the vehicle's electronic systems.
Axle-Back Exhaust Systems: Budget-Friendly Performance Choice
Enhance your WRX STI’s sound without any major performance modifications with an axle-back exhaust system. This is a budget-friendly option that still enhances your sound without major upgrades. It replaces the exhaust from the car axle to the exhaust tips. Yes, the performance gains are less than cat-back and turbo-back systems, but you’ll experience substantial sound improvement.
Resonator and Muffler Delete: Increases Cabin Noise
If you are looking for a louder-than-loud sound, a resonator and muffler delete is a more thunderous option for your WRX Subaru. Removing these components reduces exhaust restriction, resulting in a booming engine sound. Remember that this modification will increase the sound inside your car, affect the car’s warranty, and may lead to not passing emission tests, but wow, the sound might just be worth it.
High-Flow Catalytic Converters: Maintains Emissions Compliance
Upgrading your vehicle’s exhaust with a high-flow catalytic converter could be a win-win for improving performance, increasing sound, and meeting your area’s emissions regulations. However, before installing a high-flow converter, make sure it is compatible with your emission control systems.
