Browse & shop Turbo Downpipe Exhausts for your car or truck.
Downpipes are a critical component in turbocharged exhaust systems, connecting the turbocharger to the rest of the exhaust. Upgrading the downpipe improves exhaust flow, reduces backpressure, and supports increased horsepower and torque by allowing the turbo to operate more efficiently.
Performance downpipes are a popular upgrade for Subaru WRX and STI owners looking to improve throttle response, power delivery, and overall performance. Depending on configuration, downpipes can also influence exhaust sound and emissions compliance.
Downpipes for Subaru WRX & STI
Downpipes designed for the Subaru WRX and STI are engineered to handle increased exhaust flow from turbocharged engines. Compared to factory downpipes, performance options reduce restrictions and help unlock additional power when paired with proper tuning.
These downpipes are commonly installed alongside other exhaust upgrades such as catback systems and are often required for higher-performance turbo setups. Proper fitment is critical, as downpipe design varies by model year, engine platform, and turbo configuration.
Choosing the right downpipe depends on your performance goals, vehicle setup, and local emissions requirements. Some drivers prioritize maximum flow and performance, while others prefer solutions that balance power gains with street legality and daily usability.
Catted vs Catless Downpipes
Catted downpipes use a high-flow catalytic converter to help maintain emissions compliance while still improving exhaust flow. Catless downpipes eliminate the catalytic converter entirely, offering maximum performance potential but typically requiring additional considerations for emissions regulations and off-road use.
