It seems like every VRSF thread theres someone saying it's a copy of another company... Who cares if its a copy? Both the companies your claiming VRSF copied sell very high quality products so I could care less. On top of that it's not a copy, as Tiago said there are difference such as the 3.5" piping, flex pipe, and a muffler. All that makes it different than both AMS and HPF (both very reputable companies). VRSF is offering quality products without having people pay the BMW tax and all everyone does is complain and say it looks similar to some other company...
