IAG Performance Equal Length Header & Up Pipe | Multiple Subaru Fitments (IAG-EXT-1001)

Multiple Subaru Fitments Equal Length 3-Bolt Header and Up Pipe by IAG Performance

IAG's Equal Length Headers are the perfect way to add more performance to your Subaru WRX STI. By implementing a 4-2-1 configuration with equal-length tubing and merged collector, IAG is able to improve your turbo spool up by 300rpm. Due to the free-flowing design of this header, you will see gains across the entire RPM range, as exhaust flow is vastly improved. The IAG headers are fully constructed of 304 stainless steel, including cast stainless flanges! The equal length headers feature a 45mm pipe diameter for maximum flow and performance. The header also features a slip-joint expansion section to accommodate for flex caused by heat cycling. Each IAG header is fully TIG welded for maximum strength.

Each header package includes the IAG 60mm uppipe that utilizes a 3-bolt cast flange and multi-layer gasket between the manifold and uppipe, providing a stable connection without exhaust leaks. The IAG Header & Uppipe adds all of the hardware and high quality, multi-layer gaskets needed for installation including specialty copper exhaust nuts, which are proven to maintain their torque even in the extreme conditions of heat cycling present at the exhaust flange.

Due to the equal length design, these headers will alter the exhaust tone from the distinct "boxer rumble" to a smoother exhaust note.
