Silver Soldering a Cast Iron Flange to Aluminized Steel Tubing for RX 7

169 Josh Colson from Auburn Muffler and Auto Repair in Auburn, Washington, is using SSF-6 Silver Solder to braze a cast iron flange to aluminized steel tubing for better air flow. Josh cut off the restrictive cast pipe and welded on the steel tubing with an oxyacetylene torch at 1150 degrees F. The parts came off a 2000 Mazda RX 7 Turbo in desperate need of exhaust work.
