Downpipe Subaru Sti Upgrade Options and Exhaust Systems

Upgrading the downpipe on your Subaru STI can be a game-changer for performance and sound.

The stock downpipe on the STI is a catalytic converter-style design, which can restrict airflow and limit the engine's potential.

With a high-flow downpipe upgrade, you can expect to see a noticeable increase in horsepower and torque, as well as a more aggressive exhaust note.

A well-designed downpipe upgrade can also help to reduce backpressure and improve the overall efficiency of your engine.
