3" Stainless Steel Downpipe w/ High-Flow Cat

The Invidia High Flow Cat Downpipe is a performance exhaust component engineered specifically for the 2008-2021 Subaru WRX and STI models. Constructed from durable 304 stainless steel, this downpipe features a 3-inch diameter to optimize exhaust gas flow. The divorced wastegate flange design is a crucial element, as it separates the exhaust flow exiting the turbocharger. This separation minimizes exhaust turbulence, leading to a more efficient flow path and consequently, increased horsepower and torque. This downpipe is designed as a direct-fit upgrade, simplifying installation for enthusiasts. However, it's important to note that this product is not CARB Legal and therefore not for sale or use in California or any other state that has adopted California emissions standards. Verification of local regulations is recommended before purchase.
