Prosport Header and Up-Pipe 2002-2014 WRX/2004+ STI

This high-quality WRX header/up pipe combination is fully TIG-welded, with all-stainless steel tubing, cast stainless steel flanges, and a precision-cast collector.

Choose from an unequal-length design, or equal-length.  The unequal-length (UEL) design means you’ll still have that trademark Subaru boxer rumble. The equal length (EL) version gains you even more power, but the boxer sound will be gone.  Note that the equal-length header will NOT fit with the stock EJ20 (2.0 liter) oil pan. You’ll need an EJ25 (2.5 liter) oil pan. The unequal-length header fits either oil pan.

The equal length header will not fit 06-07 WRX, and will not fit Forester XT, because of a slightly different oil cooler design.

The three-bolt flange connecting this WRX header to the included up pipe is designed to reduce the chance of leaks. Includes header, up pipe, and a gasket to connect the up pipe and header. Looking for heat shielding? Try our exhaust wrap kit, and/or our Mach V EJ Header Heat Shield.

This Subaru exhaust header includes up pipe-to turbo studs, and one up pipe-to-header nut and bolt. (You’ll re-use the other two bolts from your factory manifold.)

The Prosport Header and Up-Pipe fits all 2002-2014 WRX and 2004+ STI.  Also fits EJ-motor turbo Legacy/Outback and Forester models.
