Fits 2008-2021 Subaru WRX and STI.

The Invidia HS02SWIAPD 3" Downpipe to 2.5" Exhaust Adapter is the professional solution for eliminating exhaust leaks when mating mismatched piping diameters. When upgrading to a high-flow 3-inch downpipe while retaining the factory 2.5-inch cat-back exhaust (or an aftermarket street-spec system), the flange interface often fails to seal properly. This adapter bridges that gap, providing a secure, flared transition that ensures optimal exhaust flow without the soot-staining leaks common with makeshift gasket stacking.

Precision-manufactured to withstand the high thermal loads of turbocharged EJ and FA engines, this adapter is a necessary component for a clean, reliable exhaust installation. It maintains correct backpressure characteristics and ensures your exhaust system remains quiet and efficient at the flange junction.

  • Manufacturer Part Number: HS02SWIAPD
  • Inlet Diameter: 3 inches
  • Outlet Diameter: 2.5 inches
  • Construction: High-grade stainless steel for corrosion resistance
  • Application: Connects 3-inch aftermarket downpipes to 2.5-inch cat-back exhaust systems
