GrimmSpeed Leading Front 4- Piston Brake Calipers - Gunmetal - BRZ GT86 GR86 FRS

The GrimmSpeed Equal Length Header for the 2022+ Subaru WRX is a high-performance upgrade designed to optimize exhaust flow and enhance durability. It features CNC-bent, precision-trimmed runners from a single piece of tubing to minimize welds and ensure uninterrupted flow. The true equal-length design reduces variation between runner paths, crucial for maximizing the FA24's twin-scroll turbo performance. A cast 304 stainless steel merge collector ensures smooth transitions and unrestricted flow, fitting cleanly between the stock skid plate and oil pan. The 1/2-inch thick, CNC-cut, and surface-faced 304 stainless steel flanges provide excellent gasket sealing, preventing exhaust leaks. The header's runners are crafted from heavy-duty 1.75" 14-gauge stainless steel, with internal and external welds at the flange for improved structural integrity and flow. The kit includes premium gaskets and stainless hardware for direct, bolt-on installation without requiring tuning. It maintains stock ground clearance and is compatible with the OEM skid plate.
