that was i think 1 1/2" or 2" angle that i welded flat bar to and closed the ends , became a hollow triangular tube . As i noted i measured intake volume be fore and after . 5litres before pretty close to 4litres after . It was a trial as there weren't many using that intake when i ran/did that . It was fairly new release when i bought it .
