Prosport Unequal Length Exhaust Manifold 2002-2014 WRX / 2004-2021 STI / 2005-2009 LGT / 2005-2008 FXT

Be sure to check out the dyno results sheet. The Prosport header & up-pipe added 13ft/lbs Torque and 11 Horsepower to the wheels!! Prosport headers are a work of art, you might be tempted to just hang them on the wall and stare at them all day! They are fully constructed out of T304 stainless steel, including the flanges! This set INCLUDES the pictured uppipe which uses an exclusive 3 bolt flange design between the manifold and uppipe providing a stable connection without air leaks. With a jaw dropping 45mm inner pipe diameter you can be sure your spent exhaust will exit in a hurry.

You have to see this header in person to appreciate it, the welds are just incredible! This Subaru exhaust header includes 5 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.)
