Wildcat Headers WILD288 – Toyota Supra MA61 2.8L 5M-E 1983–1986

Wildcat Headers WILD288 are engineered for the Toyota Supra MA61 fitted with the legendary 2.8L 5M-E inline six-cylinder engine. The tuned 3-2-1 interference header design improves exhaust pulse scavenging to deliver stronger mid-range torque, improved throttle response, and smoother overall engine performance.

Designed as a direct-fit replacement for the factory cast exhaust manifold, these Australian-made headers are ideal for restorations, classic street performance builds, and enthusiasts wanting improved exhaust efficiency without compromising drivability.

Engine Airflow Data

The Toyota 2.8L 5M-E engine draws approximately 5,600 litres of air per minute at 4,000 rpm and expels approximately 16,800 litres per minute of hot exhaust gas at operating temperature.

As engine rpm increases, efficient exhaust scavenging becomes increasingly important. Tuned-length headers help reduce backpressure, improve cylinder evacuation, and maintain exhaust gas velocity for stronger torque and improved throttle response.
