This high-quality header/up pipe combination is fully TIG-welded, with all-stainless steel tubing, cast stainless steel flanges, and a precision-cast collector. The unequal-length design means you'll still have that trademark Subaru boxer rumble. The three-bolt flange connecting the 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.
New! Prosport equal-length headerLike the header above, but equal-length design for more horsepower. You'll lose that boxer thump, though. Note that this header will NOT fit with the stock EJ20 (2.0 liter) oil pan. You'll need an EJ25 (2.5 liter) oil pan.
Dyno results!These numbers are before and after installing a Prosport unequal-length header/up pipe on our 2005 Legacy GT.
Turbo to Up Pipe studs The Prosport Header does not include up pipe studs. We highly advise you pick up some new ones, since it can be impossible to extract the studs from your stock up pipe without destroying them.
Set of five studs.
Prosport Header to Up Pipe Gasket This Fits only the Prosport header with 3 bolt flange.
