XForce Header & Metallic Cat Kit - Subaru Impreza GC GD GG N/A (1996 - 2007) - H2-SW11B-KIT

Transform the performance of your Naturally Aspirated (Non-Turbo) Subaru Impreza with the XForce Header and Cat Kit. Engineered for Flow, this kit features a high-efficiency 4-2-1 Tri-Y design and a 100-cell metallic high-flow cat. This combination significantly reduces backpressure compared to the factory manifold, providing a noticeable increase in power and throttle response. Please note: This kit produces an equal-length exhaust pulse and does not maintain the traditional "boxer rumble" note. It is designed only to fit with XForce cat-back systems.
