Slip couplers allow the first 24" of the head pipes to be dropped in seconds, so the transmission to be easily removed for service.

Rectangular polished exhaust tips fit below the rear valance panel (designed for use with plain rear valance panel that does not have cutouts or notches at the bottom). Includes hardware and instructions. Backed by Hooker Blackheart's Limited Lifetime warranty. Note: These exhaust systems were specifically designed to be installed with Hooker Blackheart HEMI® swap engine and transmission mounting components and headers for this same application. Attempts to install these exhaust systems with any other type or combination of engine and transmission mounting components may cause them to not provide their intended ground or vehicle component clearances.

  • The vehicle is a uncontrolled vehicle - Vehicles that were manufactured before emission control regulations took effect are called uncontrolled vehicles. Aftermarket parts regulations and anti-tampering laws do not apply to these vehicles
  • An EO legal engine swap kit is utilized (such as a GM EROD)
  • The vehicle is being used for Competition Use Only - Racing Use Only Vehicles are vehicles that are used exclusively for competition that are not registered and that may never be used on the street
