The runners were the most time consuming. We used oval bar stock and then split it down the center and hand fabricated them to go from the smaller dia. head flange to our much larger CNC oval velocity stack. We use no round to oval or square tubing of any kind. The plenum is CNC D-Shaped and angle tappered for the T/B. And lastly we machined our billet bungs for the direct port nitrous.

All and all I'm very happy with the out come. I saved 5ft. of turbo piping by swithcing to right-hand side T/B mount and improved overall flow of this unique system.
