Invidia Equal Length Big Tube Headers and Up Pipe Subaru WRX/STI/FXT/LGT (EJ20/EJ25)

This Invidia equal length big tube header kit with up pipe is listed for Subaru WRX, WRX STI, Forester XT (FXT) and Liberty GT (LGT) models with EJ20 or EJ25 engines. Invidia says the larger piping diameter and equal-length design are key factors for builds chasing 600+ horsepower that the factory manifold would otherwise limit. Smooth bends are used wherever possible to give the exhaust gases an unobstructed path, and Invidia says the equal-length layout removes the boxer rumble in favour of an aggressive, race-inspired four-cylinder sound. The headers suit stock turbos or stock-replacement aftermarket turbos with the same inlet flange, and EJ20 engines need an EJ25 oil pan and pickup for installation.
