Expreme Exhaust Manifold (Equal Length)

The Tomei Unequal Length Exhaust Manifold is engineered to boost performance and sound for Subaru WRX, STI, Legacy GT, and Forester XT models from 2002-2021. This upgrade features an unequal length design that optimizes exhaust scavenging, leading to improved turbo spool and greater power potential. The manifold's precise construction, including CNC-machined flanges and TIG-welded pipes, ensures minimal flow restrictions and a professional appearance. It helps maintain engine bay temperatures with included thermal wrap and hardware, contributing to consistent performance. The design also preserves the authentic Subaru boxer engine tone, providing a distinctive and aggressive exhaust note. While installation can be managed by experienced DIYers with basic tools, professional installation is recommended for optimal fitment and sealing, especially when combined with other performance modifications. Tuning is highly recommended after installation to maximize gains and ensure proper engine management. This part is not CARB compliant.
