Enhance Your 2020-2024 Subaru WRX & STI with Premium Exhaust Upgrades

Upgrading your Subaru WRX or STI exhaust system is a key step toward unlocking improved sound, throttle response, and overall performance. Our collection offers a wide range of catbacks, axle-backs, headers, and downpipes designed specifically for 2020-2024 WRX and STI models, ensuring precise fitment and durability for enthusiasts who demand more from their ride.

What does a catback or axle-back exhaust do for your Subaru WRX and STI?

Catback and axle-back exhaust systems replace different sections of your Subaru’s exhaust to improve flow and sound. A catback system replaces everything from the catalytic converter back, offering significant gains in exhaust flow and a deeper, more aggressive tone. An axle-back replaces only the rear section from the axle to the exhaust tips, providing a more subtle sound upgrade with easier installation.

  • Catbacks enhance power delivery by reducing backpressure
  • Axle-backs focus on sound improvement with minimal modifications
  • Both systems bolt directly to factory or aftermarket downpipes
  • Materials like stainless steel improve durability and reduce weight

How do downpipes and headers affect your Subaru’s performance?

Downpipes and headers are critical components that influence exhaust flow and turbo efficiency on turbocharged WRX and STI models. Upgrading your downpipe reduces restrictions after the turbo, improving spool and throttle response. Headers replace the factory manifold to optimize exhaust scavenging, which can lead to smoother power delivery and better overall engine efficiency.

What to expect after installing performance exhaust parts on your WRX or STI?

Installing performance exhaust components will give your Subaru a more aggressive exhaust note and can improve throttle response and engine efficiency. Depending on the extent of your upgrade—especially with downpipes and headers—a custom tune may be recommended to maximize gains and ensure safe operation. Explore our exhaust product range at Subimods to find the right parts to match your driving style and performance goals.
