Invidia Divorced Wastegate Downpipe with High Flow Cat – 2002–2007 Subaru WRX / STI GD | Polished

Maximize turbo response and exhaust flow on your GD-chassis Subaru WRX or STI with the Invidia Divorced Wastegate Downpipe. Unlike conventional downpipes that merge the wastegate and turbine outlets, Invidia's divorced wastegate design routes the wastegate flow through a separate outlet — eliminating turbulence and backpressure at the turbine exit for improved spool, more consistent boost control, and better overall turbo performance. Finished in polished stainless steel and includes a high-flow catalytic converter for improved exhaust flow over the restrictive factory cat.

Key Features

• Divorced Wastegate Design: Separate wastegate outlet routes wastegate exhaust flow independently from the turbine outlet — eliminates backpressure and turbulence at the turbine exit for improved turbo spool, more consistent boost control, and better power delivery
• High Flow Catalytic Converter: Included high-flow cat significantly reduces exhaust restriction compared to the factory catalytic converter while retaining catalytic function — improved flow without going full catless
• Polished Stainless Steel: Premium polished stainless steel construction for superior corrosion resistance, long-term durability, and a clean, show-quality underbody appearance
• GD WRX / STI Specific: Engineered specifically for the 2002–2007 Subaru WRX and WRX STI GD chassis — direct bolt-on fitment to the factory turbocharger and exhaust system
• Invidia Quality: Manufactured by Invidia — a leading Subaru performance exhaust specialist trusted by enthusiasts and professional builders worldwide
