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°F. The parts came off a 2000 Mazda RX 7 Turbo in desperate need of exhaust work.
