I dont have any clips that are good quality... But, I currently have it set up to VTA. It's VERY loud.
People say that it makes your car back fire, hesitate between shifts, burn out your catalitic converter, fowl your plugs... (blah) I personally have not experienced any of that behaivor. Others claim they have.
