Exhaust ring for the FG-73R5 radial engine. This ring is especially nice if you plan on cowling in the engine and exhaust to be directed out the bottom.
The exhaust stack is at the bottom and long enough to fit most applications. Simply cut off the excess. When installed, it has a clean look and a cool sound.
Ring dimensions: Diameter: 7-1/2 inches OD Diameter: 6-3/8 inches ID Distance from back of ring to firewall: 1-9/16 inches Tailpipe: 1.25 wide, 3.5 long
Same Principle Applies to FG73.

This is a fantastic addition to the Saito 5 cyl radial. It sounds absolutely FANTASTIC!!!
One word of advice: RTFM and follow the on-line installation instructions. If you don’t follow the instructions, installation will simply make you crazy and you will fail to install it no matter how hard you try. Follow the instructions and it just pops right on!!!!!
