its a pipe, its 2.5'' in diameter and can only really be routed in one way. You just took what nissan did with a smaller pipe and made it bigger should they sue you? Look at how many diff fab companies there are for tons of other car products do you see them on the net bitching about ohh you stole this or that? Yeah the ams MSP manifold thing was low, I dont agree with it, but to say it about pipes just sounds retarded. You can only make a test pipe one way. I dunno I think this sounds like a cry for "look people are ripping off my shit buy my stuff and not theirs."
