Hi there - have fitted my VS 3.8L with pacemaker extractors are the original manifolds had cracked. Do I need to get this modification certified? Theres a slight increase in power but definitely no noise increase (which seem to be the main considerations for a WOF, certification etc). It doesnt look like to need certification but could someone please confirm? Cheers!
