Grimmspeed 113008 Equal Length Exhaust Header for 2015+ Subaru WRX

The Grimmspeed Equal Length Exhaust Header transforms the 2015+ Subaru WRX's exhaust system by replacing the restrictive factory unequal length header with a true equal length design. This upgrade eliminates the characteristic Subaru rumble in favor of improved performance, smoother power delivery, and reduced turbo lag.

Key Features:

• Equal length runner design ensures consistent exhaust pulse timing for optimal turbo spooling
• Increased piping diameter reduces backpressure and improves exhaust flow
• Precision mandrel-bent stainless steel construction for durability and longevity
• CNC laser-cut flanges ensure perfect fitment and reliable sealing
• Improved mid-range torque and horsepower gains throughout the powerband
• Designed specifically for 2015+ Subaru WRX FA20DIT engine
• Professional installation recommended due to complex fitment

This header is engineered to work with both stock and aftermarket turbochargers, making it an ideal foundation for future performance upgrades. When combined with a proper tune, expect noticeable improvements in throttle response and overall engine performance. Note that installation requires removal of the factory header and may require additional components such as gaskets and hardware.
