Due to popular demand, Invidia has finally released a standard size, equal length raced header for the Subaru WRX, STI and Legacy GT. This header features full stainless steel finish, mandrel bends and thick computer cut flanges for optimal flow and perfect fit. Where this design differs from Invidia's traditional header design is that this header allows your to run your choice of a stock or aftermarket uppipe. This is especially handy for Subaru enthusiasts that want to upgrade to an external wastegate style uppipe but don't want to lose their great quality Invidia header.
NOTE: 2002-2005 WRX must use STI oil pan.
