Performance Highlights
Dyno testing shows this BBK system adds over 30 horsepower at the wheels compared to stock, with gains starting low in the RPM range for better throttle response and peaking at higher speeds for top-end pull outpacing factory components and many rival brands in real-world acceleration and quarter-mile times.
The CNC-mandrel bent design minimizes restrictions, while the high-flow cats maintain a deep, aggressive exhaust note without drone.
Installation and Warranty
This direct-fit kit installs in about 6-8 hours with basic tools and mechanical knowledge remove the stock manifolds, bolt in the headers, connect the mid pipe, and torque to spec. Professional help is advised if you're new to exhaust work. Backed by BBK's 1-year limited warranty.
Choose the BBK 16333 for a header system that transforms your Mustang's exhaust into a high-revving powerhouse, backed by decades of American-made expertise perfect for anyone serious about extracting every bit of potential from their 5.0L Coyote engine.
BBK
BBK Performance has been building bolt-on performance parts in the USA since 1988, focusing on dyno-proven gains for Ford, GM, Dodge, and Jeep platforms. Founded by Brian Barry in Southern California, BBK has grown to two U.S. facilities with nearly 200,000 square feet of R&D, manufacturing, and distribution space dedicated entirely to domestic performance. Popular Upgrades BBK cold air intakes are among the most popular first mods for Mustang, Camaro, and F-150 owners, delivering 10–20 hp gains on naturally aspirated engines with no tune required on most applications. Performance headers improve exhaust scavenging and add noticeable low-end torque on V8 and V6 engines. BBK throttle bodies, fuel injectors, and mass air meters complete the intake side upgrade path for owners building toward larger power numbers. Do BBK cold air intakes require a tune? Many BBK cold air intakes are designed to work on stock or lightly modified engines without a tune by using the factory MAF sensor...

Headers & Manifolds
Performance headers and exhaust manifolds are among the most effective bolt-on upgrades for improving exhaust scavenging, increasing horsepower, and giving your engine a more aggressive exhaust note. Whether you're building a street machine, a track car, or a diesel work truck, the right header or manifold set unlocks real performance gains across the RPM range. Popular Upgrades Top-selling header and manifold products include long-tube headers from BBK and Kooks for V8 muscle cars and trucks, stainless steel shorty headers from Stainless Works for tight engine bay fitments, high-flow cast iron exhaust manifolds for diesel platforms from BD Diesel and ATS Diesel, and turbo manifolds from aFe Power and Invidia for forced-induction builds requiring optimized turbo positioning. What is the difference between long-tube and shorty headers? Long-tube headers route exhaust primaries farther down the chassis before merging at a collector, which improves mid-range and top-end power but requi...
