Hi Everyone, its nice to be back from Sweden and back driving the car again. I just bought the Vectra C air intake pipe , High airflow filter and some wipers.I also had to get the timing chain done which was not cheap. I also kill a sheep the other day which wreck the dumper, big dent in the bonnet, pushed in the head light and fog light. Still have to get them fixs yet tho. My question is this .... while im getting these items fixed i thinking of removing the precat but im concerned about the level of noise that follows. i have read that most say they do love the new sound but did not expect how loud it sounded, Can you tell me out of 1 to 10 and 10 being the max how much louder it is since being removed and can you live with it.
