aFe Power Twisted Steel Long Tube Headers with Mid Pipes (48-36316-YC) improve flow and performance for 1996-1999 BMW M3 L6 3.2L S52 engines. These headers use 3-to-1 mitered collectors to reduce turbulence and increase exhaust velocity, resulting in gains in horsepower, torque, and throttle response. Optimized tube lengths support pulse control technology, and 3/8-inch laser-cut flanges provide a leak-free seal. The system includes 400 CPSI high-flow catalytic converters, 1.625-inch mandrel-bent stainless steel tubing, and a single 2-inch transition for reduced back pressure. OE-style flanges, band clamps, and O2 extensions ensure a hassle-free direct fit installation.
