Designed using a Maximum Motorsports K-member and manual transmission. May not fit other configurations without modification. 3" Matching Short X-pipes with with converters are also available to connect up to the Cat back Exhaust (Minor Exhaust Fabrication Required) Because they are 3-inch, you will need a new 3" cat-back exhaust system or modify the stock cat-back to fit. We highly recommend a new 3" system. The 87-93 Mustang GT 3" cat-back Flowmaster Part #17396 was used with required modifications.

Note: These BBK Long Tube Headers require the use of Front O2 wire harness extensions - these are not included and are recommended for installation. Please check the GEN Coyote engine that you have and order the correct harness:

- GEN1 Coyote 11-14 requires Part #1112
- GEN2 Coyote 15-17 requires Part #1119
- GEN3 Coyote 18-23 requires Part #1121

Put a Coyote 5.0 in Your Mustang!
These BBK Coyote swap headers are constructed from mandrel bent high flow 1-3/4" tubing with 3" collectors making them perfect for both naturally aspirated and supercharged builds. These full length headers will help give your Coyote powered Mustang a throaty exhaust note. The titanium ceramic coated finish is very durable and helps hold in heat, improving flow and reducing under hood temperatures.

Quality Construction BBK Coyote swap full length Mustang headers are made from 1-3/4" CNC-machined mandrel bent tubing with 3/8" thick die-stamped flanges. The full length primary tube design creates unrestricted and balanced airflow for ultimate horsepower gains. These headers are pressure tested to ensure leak free performance.

Installation These Headers were designed using a Maximum Motorsports K member and manual transmission. May not clear with other combinations. For use with BBK Performance short mid pipe # 1786
