More Power and Torque. BBK designed this H-pipe with high-flow catalytic converters to provide a significant increase in horsepower and torque over the restrictive stock factory catted pipes. Increases of 14 to 22 RWHP have been seen when installed in conjunction with BBK Long Tube Headers. Muscle Car Rumble. This free flowing BBK mid-pipe for the 1996 to 2004 Mustangs not only increases power, but it also adds a deep muscle car rumble to the sound of your exhaust with its classic "H" crossover pipe design.
Rugged BBK Construction. BBK constructs their H-pipes from free-flowing 2-1/2" diameter CNC mandrel bent aluminized tubing to ensure maximum flow and features OEM style hangers that attach in the stock locations for a perfect fit.
Application. This BBK Shorty Catted H-pipe is made to fit the 1996-2004 GT, 2001 Bullitt, 1996-2004 SVT Cobra and 2003-2004 Mach 1 Mustangs with BBK Long-Tube Headers installed.
