What do you guys think about the redesigned ceramic coated complete system??Does anyone have one yet?? if so, does it increase top end power as well as bottom end?? i was thinking of putting on this system, twin air filter, airbox vents, carb rejet. sound good?? thanks

 

I orderd my Big Gun System last night. I to am wondering about the effect it will have. I already have the jets for the carb and will be using a 40 idle jet and a 158 main with the airbox lid vented, also raise the needle 1 notch. I have some buddies that have done this and seen a great power gain. Here is a great link for the Big Gun Exhaust
