Hmmm
More Power ...
Extractors will improve power :
A 2.5inch high flow single is more than enough ....
But expect to lose some bottom end , at the same time , from around 2500RPM - youl feel more power ....
You need some back preassure , so the larger you go [ AKA free flowing ] the less back preassure there will be , so you lose some power while back preassure is built to a more fav level [ More RPM ] ....
You could go 3 inch , but the power might come on at around 4000RPM , possibly great for drag racing , but P Poor for daily driving ....
So , you want more power - worse fuel ecconomy ? [ Full 2.5 System ]
More power - Better fuel ecconomy ? [ Extractors ]
Stuff the price of fuel - I wana buy new tires every week ? [ How much $$ you got ? ]
