It’ll work for my needs. 459cc HF engine. Regarding the “weld quality” I don’t know if I’d truest screwing rigid pipe coupler>rigid pipe>muffler without some bracing.Also I had to grind out the edges to fit the wider bolt hole pattern and make sure to line up the exhaust outlet holes so there wouldn’t be exhaust flow interference/turbulence.
