Secondly, don't expect to much change with extractors. It makes it sound better so it give the impression of more power. From my experience it did not make much change.

Just bought a 1998 Discovery 2 for the beach with the 3.9 motor. Can anybody tell me of their experiences in fitting Genie Header Extractors please? Is there a significant / noticeable increase in HP, volume, torque etc? I'll be trying to fit them myself so any hints welcomed.
Cheers
