I just installed a Cummins Onan 2.5HGJBB-1121 generator
. It has a 1.25" OD exhaust pipe. I need a 4 to 8 inch exhaust pipe tip (the tail pipe must extend 4" beyond the widest point of the trailer wall). I can't find one anywhere on line. I do find a Gibson 500415 Polished Stainless Steel Exhaust Tip with 1.5" ID, but this is too big. Does anyone know where I can find with a nice looking tip? If not I may need to cut up a longer tail pipe and "McGuyver" it together.
