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. Â 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. Â 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. Â Also fits EJ-motor turbo Legacy/Outback and Forester models.
