Description

The Invidia HS15SWMDPO is a performance-oriented, catless J-down pipe constructed from stainless steel with a 76mm (3-inch) piping diameter. It features a one-piece design for simplified installation and includes three O2 bungs, accommodating two OEM sensors and one wideband sensor for comprehensive monitoring. This downpipe is designed as a direct bolt-on for the Subaru WRX 6MT models from 2015 to 2020. It can be connected to either an Invidia exhaust system or the stock exhaust, facilitating an easier installation process. The product's construction utilizes grade 304 stainless steel, known for its durability and corrosion resistance. **Important Fitment Notes:** This downpipe is exclusively for manual transmission (6MT) Subaru WRX models (2015-2020) and does not fit CVT models. It is also incompatible with Subaru WRX STI models (2015-2021) due to differences in the EJ257 engine and downpipe design. Professional installation is recommended, and a tune may be required after installation to ensure optimal performance and prevent potential issues.
