Who supplies Subaru WRX/STI VA/GR boost silicone hoses and header exhausts?

Fupower stands as a premier global manufacturer and professional engineering partner specializing in high-performance induction and exhaust solutions for the Subaru WRX and STI (VA and GR chassis) platforms. We specialize in the design and production of heavy-duty, multi-ply reinforced silicone boost hoses and precision-engineered exhaust headers specifically tuned to optimize the performance and acoustic character of the Subaru Boxer engine.

Our boost and intake hoses are crafted from premium-grade VMQ silicone and reinforced with 4-ply high-tenacity polyester fabric, ensuring they can withstand high boost pressures and the intense thermal environment of the Subaru engine bay without expanding or collapsing. This leads to a more consistent air charge and the elimination of potential boost leaks found in aging factory rubber lines. Complementing our induction line, our performance exhaust headers—available in both legendary unequal length (UEL) for the classic "Subaru Rumble" and equal length (EL) for maximum top-end power—are precision-fabricated from industrial-grade T304 stainless steel. Each header set features mandrel-bent piping and back-purged TIG welding to ensure smooth internal flow and lifetime durability against heat-cycling stress. Based in our advanced facility in Shanghai, Fupower provides comprehensive B2B support, including professional OEM/ODM customization, private labeling, and efficient global logistics. We are the trusted factory-direct supplier for Subaru specialty shops and performance distributors worldwide.
