H-Pipe by BBK®. BBK Performance mid H pipes are specifically designed to be used with BBK full length headers to complete the installation to the cat back exhaust system. All BBK Short mid off road H-pipes feature 2.5” diameter CNC mandrel bent aluminized tubing to ensure maximum exhaust flow for increased horsepower and torque. They are designed to be used for Off road Racing only as they do not have any catalytic converters.
- Provides optimal exhaust flow for the most possible increase in horsepower while retaining an exhaust system
- 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
- Bolt-on installation; no cutting or welding required
- Available with or without high-flow catalytic converters
- H-pipes without catalytic converters are not street legal and are intended for off-road use only
- Limited 1-year warranty
- Proudly made in the USA
Get the most horsepower possible from your V8 engine with a BBK High-Flow H-Pipe. On a typical V8 engine, one cylinder on each bank fires within 90 degrees of crankshaft rotation of another cylinder on the same bank. The resulting exhaust pulses are very close together as they travel through the exhaust system. These close firing cylinders are competing for space in the exhaust pipe, which creates backpressure and reduces power. When the two close firing cylinders are exhausting on one bank, there is nothing happening in the other bank, so connecting both sides with an H-Pipe effectively enlarges the exhaust system, allowing these exhaust pulses to exit through both sides of the system. The exhaust pressure on both banks is equalized and power is increased at all engine speeds. H-Pipes work similarly to X-Pipes, however they generally will provide more low end grunt instead of high rpm power, and the exhaust note is somewhat deeper.
These H-Pipes are designed to connect BBK full length, long tube headers to the factory exhaust system, in a bolt-on installation, with no cutting or welding required. They’re constructed from large diameter tubing that is CNC mandrel bent. Mandrel bending ensures that exhaust flow will be consistent for the length of the tube and CNC control ensures that every bend is made according to design. Each pipe includes bungs to mount the O2 sensors and street legal versions come equipped with high-flow catalytic converters. The off-road pipes do not have catalytic converters and these are intended for off-road, race use only. In some cases a tuner will be required to switch off the rear O2 sensors.
BBK High-Flow H-Pipes come with all necessary hardware, as well as detailed instructions to guide you through the installation. Every H-pipe is backed by a 1-year limited warranty against defects in materials or workmanship, as long as the product was installed according to BBK guidelines.
