Description

The JBA Performance Exhaust 6689S long tube headers are designed to be the number one choice for maximum performance gains and high RPM efficiency in 2015-2019 Mustang 5.0L vehicles. They also include oversized exhaust ports to accommodate ported cylinder heads, extra thick 3/8" one-piece flanges to prevent leaks caused by warping, and patented JBA Firecone® merged collectors for smooth flow and improved exhaust scavenging. The design aims to maximize ground clearance, which is beneficial for lowered vehicles. Installation includes O2 sensor provisions for proper connection with EFI systems. Note that these headers are intended for specific 2015-2019 Mustang 5.0L applications.
