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.

* H-pipe allows exhaust from both banks to exit using both sides of the exhaust system, for the least restriction and greatest exhaust flow
* Makes it easy to connect BBK full length, long tube headers to the stock exhaust system
* Large diameter tubes are CNC mandrel bent to maintain consistent flow throughout the length of the exhaust
