Header tech; do smaller tubes,,,,,,, - 07/18/15 05:48 PM
Work well if you can get them pretty much straight off the flange and out ten inches or better? I built 2 1/8 x 30 x 4 inch headers, and they seem to work well but after reading ANDYF's response on another thread I wonder if there might be enough benefit to try a different tube size, like two inch with a 3 3/4 collector. Andy, or anyone else have back to back data to show the difference?
Here is a pic of my current tubes, and the new ones I could go almost exactly in line with exhaust flow at the flange, for an exit angle.
