STI Performance Exhaust (STI)
Mounted behind the catalytic converter, the STI Performance Exhaust System provides smooth mandrel bend construction to help reduce exhaust flow restrictions, allowing the engine to `breathe` more efficiently. The exhaust system includes a free-flowing center pipe after the catalytic converter that splits into two pipes and mufflers with engraved STI tips.
