Upgrade your Subaru WRX’s performance and efficiency with the IAG Performance Equal Length Header, engineered to optimize airflow and reduce turbulence for maximum power. Designed specifically for the 2015-2021 WRX with the FA20 DIT engine, this header addresses the limitations of the OEM and unequal-length (UEL) headers.

Features:

• Optimized Airflow: Equal-length tubing minimizes turbulence, allowing exhaust gases to exit the engine ports efficiently, improving throttle response and overall performance.
• Protects Your Engine: By reducing hot spots and maintaining lower, more stable cylinder temperatures, this header helps mitigate the risk of ringland failure common with UEL setups.
• Premium Stainless Steel Construction: TIG-welded 304 stainless steel pipes and cast stainless flanges ensure long-lasting durability. Inner diameter is increased to 45mm for improved flow, and turbo port flanges are widened to 42mm. A slip-joint expansion section accommodates thermal flex.
• Complete Installation Kit: Comes with engine port gaskets, turbo port gasket, and all necessary hardware for a straightforward installation. Average installation time is 3-4 hours for those with moderate mechanical experience.
