Our famous stepped head pipes now have an OEM-correct O2 sensor port (bung) welded in and ready to plug the factory EFI closed loop sensor to. The port is positioned in the same location and exit angle of the factory version. We have also ensured that your sensor is seated the same distance as the factory version. A set of bung plugs have also been included for pre-07 bikes that are not running the later closed loop EFI system.
Testing of the New Hooker Troublemaker pipes found an additional 18.8 rear-wheel horsepower and 5.5 lb/ft of torque over a stock 2001 88ci Fatboy. Independent testing performed at Speed’s Performance Plus.
Each set of Hooker Rebels and Troublemakers comes with competition baffles and all the mounting hardware
