Hellion 1-3/4" 4 into 1 Turbo Header – 2015–2026 Mustang GT (Coyote 5.0L)
Maximize the performance of your S550 or S650 Mustang with the Hellion 1-3/4" 4 into 1 Turbo Header, engineered exclusively for use with Hellion Twin Turbo Systems. Whether you’re chasing big dyno numbers or laying down 8-second quarter-mile passes, this header delivers the flow and reliability your build demands.
Featuring 1-3/4" stainless steel primaries and a 4 into 1 collector, this header is designed for serious horsepower — proven to support up to 1700whp. Compared to restrictive factory manifolds, the tubular design dramatically increases exhaust flow, feeding your turbochargers more efficiently for greater power gains. With provisions for front O2 sensors, these headers are as functional as they are powerful.
Whether paired with the Hellion Sleeper or Hellion Top Mount System, this bolt-on header ensures a factory-like fit and uncompromised performance. Built from premium stainless steel and tested under extreme conditions, it’s the ultimate foundation for any mild-to-wild turbocharged Mustang build.
