More Horsepower and Torque. Improve the performance of your 2011-2017 5.0L Mustang with a set of BBK 304 Stainless Steel Long Tube Headers. These BBK Long Tubes will greatly improve your Mustang's exhaust flow over the restrictive factory manifolds and increase your Pony's horsepower and torque. Significant increases of about 30+ HP have been seen when installed with a matching BBK Shorty X-pipe or Midpipe Adapter.

Quality Construction. BBK Long Tube Exhaust Headers are manufactured from 1-3/4" CNC mandrel bent 304 stainless steel tubing for unrestricted airflow. One piece laser cut 3/8" header flanges are featured for added strength, leak-free performance and OEM fit. These headers are completed in a polished finish for good looks and include new gaskets and the necessary hardware for installation.

Recommended Upgrade. To realize the full power potential that these Long Tube Headers have to offer, AmericanMuscle recommends a custom tune with a Handheld Tuner to reprogram the Pony's computer (ECU) for proper operation.

Additional Required Upgrades. BBK Long Tube Headers require the use of a BBK Shorty Midpipe, part# 1655 or 1658, for S197 (2011-2014) GT or the BBK Long Tube Header Adapter Mid-Pipes part# 1816 or 18160, for the S550 (2015+) GT for proper installation.

Application. These BBK 1-3/4" Stainless Steel Long Tube Headers are specifically designed to fit the 2011-2017 GT Mustangs equipped with the Coyote 4 valve 5.0L V8 engine.
