Subaru WRX STI Catalytic Converter

The Subaru WRX STI Catalytic Converter changes out the exhaust for cleaner and safe emissions while maintaining the punchy feel that enthusiasts love. Its durable honeycomb core featuring a coating of platinum, palladium, and rhodium continuously changes poisonous gases into inert water vapor and nitrogen without wearing out. The Catalytic Converter of the Subaru performance sedan is designed for optimal functionality. As a result, the WRX STI engine spools quickly thanks to low backpressure. With peak horsepower accessible, highway pulls and back road sprints are thrilling. This unit bolts into the factory exhaust path of every 2015 and newer Subaru sport compact in the WRX STI lineup. This means you get accurate fitment while maintaining ground clearance and proper sensor placement. With minimal obstruction of gas flow, this part enhances fuel economy, reduces fume levels in the cabin, and allows the on-board computer to avoid putting on a check engine light. This means you can rely on it day-to-day as well as on track days. Another advantage of the design is its structural integrity. The strong stainless shell protects the ceramic core from debris, and heat cycles don't crack cheaper models. The stock oxygen sensors work in tandem with the Catalytic Converter to provide real time feedback. This feedback lets the Subaru control module improve air fuel ratios for maximum torque and minimal pollution. These carefully added components make the WRX STI Catalytic Converter a unique product in the performance market that blends environmentally friendly materials with race-bred strength that owners can rely on for thousands of spirited miles. Frequent spirited use in a Subaru WRX STI, especially in colder climates, means the underbody temperatures will be high enough to light off the Catalytic Converter. This reduces cold start smog. The owners of any version of the Subaru WRX STI sedan know how perfectly the device pairs with the stock sensor logic. Because it has been chosen as an original Catalytic Converter for enthusiasts, value would be reinforced.
