Quality Construction. Borla Long Tube Exhaust headers are CNC mandrel bent from 1-3/4" 16 gauge aircraft-quality T-304 stainless steel tubing for unrestricted airflow. They feature one piece 3/8" header flanges for added strength, leak-free performance and an OEM style fit.
Recommended Upgrade. To realize the full power potential that these Long Tube Headers have to offer, AmericanMuscle recommends a Bama custom tune with a Mustang Handheld Tuner to reprogram the vehicles computer (ECU) for proper operation.
Required Upgrade. The Borla XR-1 Long Tube Mustang Headers will require the use of a Borla ATAK, Borla 'S' Type, or Borla Touring system with included X-pipe for proper installation (See drop down option above).
Application. These Borla XR-1 Long Tube Headers are specifically designed to fit the 2011 to 2014 GT Mustangs equipped with the 4 valve 5.0L Coyote engine.
