Subaru WRX STI EJ Downpipe Kit - ES-SW07-KITB

Enhance the performance of your Subaru WRX or STI with the Xforce high-quality Downpipe Kit. Designed specifically for the legendary EJ20 and EJ25 Turbo engines (1994–2007), this kit drastically improves exhaust gas flow by replacing the restrictive factory unit. Experience increased power, faster turbo spool, and improved throttle responsiveness. The precision-engineered cast bell-mouth design ensures that exhaust gases exit the turbine wheel and wastegate with minimal turbulence, unlocking the true potential of your Subaru.

Note: This downpipe is specifically engineered to bolt up ONLY to an Xforce cat-back exhaust system. Tuning is highly recommended after installation to ensure engine safety and peak performance.
