Yeah it actually doesn't say who the manufacturer of the header is...
The other thing is that if that is an actual picture of the header they are selling they are lying about it being a 4-2-1 header... the picture is of a 4-1 header... normally a 4-2-1 would be about double the price they are selling that one for... Just a bit of info for you & your bro...

that is a copy of the pacesetter header
just like the obx and weaponr stuff is , it was prob made from the same company over seas with child labor
