Many users assume that all OB 7.3 exhaust parts are basically the same, but my extensive testing shows otherwise. I’ve installed and compared several options, paying close attention to materials, fit, and durability. The GXP Heavy Duty Stainless Steel Bellowed Up Pipe Kit truly stood out in how it handles the heat expansion with its heavy-duty bellows and 409 stainless steel build.
