BBK's R&D department developed these Mustang GT Long Tube Exhaust headers with one thing in mind. Getting even more horsepower and torque out of your 4V 5.0L V8 Coyote Mustang!
These BBK long tube headers are constructed with 1-7/8" (recommended for Supercharged or highly modified application) CNC Mandrel-Bent tubing and solid 3/8 laser cut exhaust flanges. Topped off with a chrome finish, these headers will greatly improve your Pony's exhaust flow for power gains around 30+hp.
To get the most from your American-made muscle car's new upgrade, it's recommended to get a tune with SCT's X4 or BDX handheld tuners. Reprogramming the car's ECU will allow you to reap the full benefits of these BBK Longtube Headers.
For use with S197 Mustangs GT/Boss 302, you'll need to purchase BBK's High-Performance Shorty Mid-Pipes (1655 or 1658). For use with the S550 Mustang GT, you'll need to purchase BBK's Longtube Header Adapter Mid Pipes (1816 or 18160) and the O2 Extension Harness and Hardware Kit (16332).
