ok I been searching and searching but I cant remember where I seen the post at. I am looking to buy and make a header for my 2010 1.6 ecotec sedan. I cant remember if it was a b16 or a d16 header I needed to buy. also can the factory mani mount be cut off and rewelded (welding to be done by local welding shop) to the new header instead of having one made. thanks for any input.
