| NAPA has 90s up to 5 inch dia. I needed a 6 inch stack and 90 and bought a straight 10 ft stick of 6 inch exhaust pipe and made the stack and a 90. Went to heating supplier and borrowed an adjustable 90 furnace elbow. I traced a pattern of the sections and cut them out of the staight stick and welded them into a 90 with the mig. Local KW plant was using 5 inch stacks and is going to 7 in on new engines. A big truck parts supplier would have large diameter elbows. Bob Chillicothe, Oh | |
