BBK 86-93 Mustang 5.0 High Flow H Pipe With Catalytic Converters - 2-1/2
Hi-Flow Catted H-Pipe (1521) by BBK. Emissions: EPA compliant. Main Piping Diameter: 2.5". H-pipes increase exhaust flow to gain horsepower by allowing both cylinder banks to make use of both sides of the exhaust system. These high-flow H-pipes are constructed from large diameter tubes that are CNC mandrel bent to ensure maximum flow and the most horsepower increase possible. These short versions are designed to connect to BBK full length, long tube headers, and come with catalytic converters or in off-road style without converters. Pipes without catalytic converters are for off road, race use only. Bolt-on installation; no cutting or welding required.
