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 Unequal 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 4-1 collector 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.
