Quote: Since we're talking about building headers, where can I get that star shaped filler piece that fills in the space between the primary pipes before the collector is put on? I don't know what that piece is called, so its hard to find it online.
The "merge collector"? or just the piece with the 4 holes in it that is filler?
I beleive he is asking about the filler where the 4 tubes come together and form a point in the collector.
