BBK 351 Swap Shorty Unequal Length Exhaust Headers; 1-5/8 in. Titanium Ceramic; Ford Mustang 1979-1993 (1511)

Fits 1979-1993 Ford Mustang models, including GT, LX, SVT Cobra, and SVO, for 351W-based engine swaps.

BBK Performance unequal length shorty exhaust headers (MPN 1511) are engineered specifically to facilitate a 351W engine swap into the Fox Body chassis while maintaining compatibility with factory-style exhaust systems. Built using 1-5/8-inch CNC mandrel-bent tubing, these headers eliminate the restrictions of OE manifolds to provide increased exhaust flow, supporting improved horsepower and torque.

Each header features a 3/8-inch laser-cut flange for added structural integrity and a guaranteed leak-free seal against the cylinder head. The headers are robotically and precision hand-welded, then pressure-tested to ensure long-term reliability under high-heat conditions. This set is finished in a durable titanium ceramic coating for superior heat management and corrosion resistance.
