2011-2014 Ford F150 5.0L JBA Cat4ward Natural Stainless Shorty Headers | 1688S

Drop-In Replacement, 50-State Legal Shorty headers for your F150 5.0L

The stock exhaust manifolds on your 2011 to 2014 F150 5.0L hold your aggressive truck back from making horsepower and torque that's easily in reach. JBA's Cat4ward Shorty Headers can help unlock your F150 5.0L's hidden potential by making exhaust outflow much more efficient, all in a package that's 50-State Legal and CARB-Approved. JBA's headers improve on your stock exhaust manifold's design in almost every way imaginable, giving your truck a nice bump in power output and fuel economy without removing or displacing your factory mid-pipe or catalytic converters. The F150 5.0L Cat4ward shorty headers use larger tubing, smoother bends, and a specialized collector to reduce back pressure and get your aggressive 2011 to 2014 F150 running at its very best, no matter what state you happen to live in.

Large Exhaust Ports with Mandrel-Bent Primary Tubes and Efficient Collector

JBA carefully designed and constructed their F150 5.0L Cat4ward shorty headers to squeeze every last ounce of performance out of your truck in a CARB-legal package that drops right into place of your F150's stock manifolds. The headers each feature oversized exhaust ports that aid in clearing your 5.0L's cylinders of exhaust gasses, which lead into 1-5/8" CNC mandrel-bent primary tubes that allow for a much smoother flow of exhaust gasses with less back pressure than stock. The primary tubes lead down to a specialized collector that's fitted with JBA's Firecone velocity spike design that greatly improves scavenging for better performance. Each header comes standard with a 3/8" thick, laser-cut flange and installs right in place of your F150's factory shorty headers. Both headers in this kit are made out of 409 stainless steel and have a natural stainless steel finish.
