We are converting the SuperCircuit twin scroller header to fit this 2.5L single scroll engine.

Ta Da! The final results of the conversion is here! Fit nicely to the Subaru Impreza WRX STI 2.5L (EJ25) single scorll turbo engine for a smoother exhaust flow and higher performance. The mass production version of this header is on the way!
