PSR Racing Equal Length Exhaust Manifold/Headers For Subaru Impreza 92-14

PSR all stainless steel exhaust manifolds are a tried and true solution for improving more power and torque through the entire RPM range of your Subaru. These single scroll Equal length exhaust manifolds suit all EJ20/EJ25 single-scroll turbo Subarus including Classic GC8/GF8, GDA/GDB, GH/GE/GR/GV and the final gen VAB STI. Lost wax finished flanges with a 4-2-1 collector design and a smooth inner surface allows for better flow and reliability. Stable connection and air leakage of the exhaust manifold is avoided by the 3 bolts flange design up-pipe. A larger pipe diameter of all sections enables better flow of exhaust allowing for higher power and torque and better turbo spool.

All PSR headers are covered by a limited 1 year warranty.

Note: EJ20 Motors will require EJ25 Oil Pan and Pickup for installation. 06-07 WRX/STI and 03-08 Forester XT will need to modify OEM oil cooler assembly.
