vauxm Hi there! Im thinking of removing my pre-cat and i was just wondering if i have to remove the lambar sensors from the down pipe or can i just unplug them from the loom and keep them untouched on the pipe? I heard that they can get dameged if moved?
vocky you can leave them in place, but it's better to remove them if possible whatever you do DO NOT SPRAY THEM WITH WD40, it kills the lambda 🙁
