PLM Equal Length Headers 2015-2021 WRX

The 2025 redesign of our PLM Power Driven Turbo Header now features premium 304 stainless steel and a 2-piece clamp-on design for enhanced adjustability and effortless installation. By eliminating the bulky and restrictive factory manifold, this turbo header unlocks significant low-to-mid-range power gains, thanks to its equal-length runner design that optimizes exhaust flow for maximum engine performance. Engineered as a direct bolt-on replacement, it seamlessly connects to the stock location while offering superior flow dynamics compared to the OEM manifold. Utilizing 1.5" piping, it efficiently balances heat absorption and dissipation, ensuring durability while maintaining the strength to support turbo weight.
