    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 S550 Upgrades. Installation of these BBK Long Tube Headers on a 2015-2017 S550 Mustang will require the use of a set of BBK Long Tube Header Adapter Mid-Pipes part# 1816 or 18160 and an O2 Extension Harnesses and Hardware Kit part# 16332. Please see options listed above.

    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.

    Application Note.

    Can I use these with the Borla ATAK 3” exhaust?


    Can i run these headers with cats and no tune?like if i run them no tune would I destroy my engine ?


    • The BBK 1-3/4 in. Stainless Steel Long Tube Headers for the 11-17 GT Mustang will recommend a tune with the Long tube headers installed. It could cause potential damage after time without a tune. The tune will provide you with maximum performance gains as well for this product as well.

    Which strikes a better balance between heat reduction and corrosion resistance, these? Or the BBK Ceramic coated long tubes?


    • We would go with the ceramic headers. The ceramic will be less prone to heat and will not rust!

      BBK Stainless Long Tube Headers

      My research led me to go with BBK for their reputation for good quality with the sound I wanted. I combined the headers with the BBK catted shorty X-pipe, and with Borla's Type S axle-back. The sound is phenomenal in my humble opinion. You can easily hold a conversation or listen to music when cruising. This combination gives me drone free cruising. When you get on it and the revs go beyond 3000 RPM, the growl is vicious. I had a shop install these who specialize in Mustangs. It took about 6 hours. It is hard to be specific on performance gains because I installed a Steeda CAI along with a Bama tune at the same time. With all of these changes, the car is a different animal. Very quick!
