I spoke to 2 different people when I called up. When I asked if it was a direct copy of the Japspeed/J-perfomance and they said no but it's very similar. It also has a 4.5" tip instead of 4". I emailed them telling them about the mistake I made and a mate of mine (joshuaj on here) is going to be selling me his instead. His has only been used for about 1000miles, if that, so I'm fine with that peace of mind as well lol
