aFe Twisted Steel Long Tube Headers with Catted Mid Pipes 3-to-1 Mitered Collectors 96-99 BMW M3 L6 3.2L S52

Designed to enhance exhaust flow and engine efficiency, these long tube headers with mid pipes (catted) utilize precision-formed 3-to-1 mitered collectors that significantly reduce turbulence and maximize exhaust velocity. The improved gas scavenging translates into measurable gains in horsepower and torque, while contributing to a more responsive throttle feel under various driving conditions.

The headers feature optimized tube lengths engineered to support true pulse control technology. This design ensures consistent exhaust pulse timing, minimizing backpressure and enhancing overall flow dynamics through the system. Materials and construction are selected to withstand high thermal and mechanical stresses typical of performance applications, maintaining durability and long-term reliability.

Key technical features include:

• 3-to-1 mitered collectors: Precisely formed to reduce turbulence and improve exhaust velocity for increased engine output.
• Optimized tube lengths: Calibrated for pulse control technology to enhance scavenging and maintain smooth exhaust flow.
• Catted mid pipes: Integrated catalytic converters comply with emissions while preserving performance gains.
• Heavy-gauge steel construction: Ensures structural integrity and resistance to thermal fatigue.

These components are engineered to integrate seamlessly with the existing exhaust system architecture, maintaining proper fitment and alignment. The design focus on flow efficiency and durability makes them suitable for demanding street and track applications where consistent performance and reliability are critical.
