It follows the proven layout of PLM's FA20 header, but the primary tubing is enlarged to 48 mm so it is better matched to the airflow and displacement of the 2.4-liter FA24.\u003c\/p\u003e\u003cp\u003eThe unequal-length design keeps the boxer sound people want while targeting stronger low- and midrange response. PLM uses mandrel-bent stainless tubing, TIG welds, bellow flex joints, a true 4-1 merge collector, and CNC laser-cut flanges, so it is built as a functional power part rather than just a sound change.\u003c\/p\u003e\u003ch3\u003eWhy I would choose it\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eFA24-specific 48 mm primary tubing\u003c\/li\u003e\n\u003cli\u003eUnequal-length layout for the traditional boxer exhaust note\u003c\/li\u003e\n\u003cli\u003eHigh-quality bellow flex joints to manage engine movement\u003c\/li\u003e\n\u003cli\u003eStainless-steel mandrel bends and TIG welds\u003c\/li\u003e\n\u003cli\u003eTrue 4-1 merge collector\u003c\/li\u003e\n\u003cli\u003eCNC laser-cut flanges\u003c\/li\u003e\n\u003cli\u003eDirect replacement for the factory manifold\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFitment\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e2022+ Subaru BRZ with FA24\u003c\/li\u003e\n\u003cli\u003e2022+ Toyota GR86 with FA24\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003ePLM references a 28 whp and 14 lb-ft result from testing of its earlier FA20 version; that is context for the design, not a guaranteed FA24 result.
