Exhaust is completed, instead of using Pat's well engineered exhaust system. I made my own exhaust system,1" ID flex stainless steel tubing, two exhaust clamps of 6061 T6 aluminum the finned one at the engine and one to clamp the exhaust pipe to the B&S 3/4NPT muffler intake side. Also two strap clamps, one to hold the exhaust pipe to the frame and a larger one to clamp the muffler.. The strap clamps are of HRPO steel1mm steel thick] that I formed and drilled for mounting screws. The strap clamps got a black oxide finish, then hot waxed for corrosion resistance. Photo captures it all.
