what would be the best performance brand of extractors to suit vn/vp v6 at the momment im told pacemaker
Real cars don't power the front wheels, they lift them
It depends on what you are doing to the car.
Pacemakers will be one of the best as far as flow goes, so if you are planning big engine mods they are the way to go. There are two different primary pipe sizes to choose from though.
But for most street applications, the difference in price between Pacemaker and a cheaper set won't really be justified in the performance difference. EG: $100 difference in price won't net $100 worth of improvement.
