Hey guys so I have a 2009 fg g6 completely stock except my knn air filter and “2.5” red back exhaust system I’m on my red p plates so can’t do a whole lot with the car and am getting told a lot of different things will work best so I’m just trying to see what other people have done and getting a few extra inputs was thinking about going for the extractors and high flow cat before a tune is it really worth it or am I better off just re tuning until I can go for the supercharger or turbo??

Need help with upgrading my 2009 fog g6 it is completely stock other than a knn air filter and “2.5” bolt on red back exhaust system what would be best to do before getting it tuned I’ve been told not to worry about to much until I goto the turbo any info is greatly appreciated
