The stainless 2.5" Elbow X Pipe Kit w/ Small Crossover is constructed from our SS Bros SS304 45° elbows that are pre-cut and pre-cleaned. Our goal is to eliminate the labor intensive fitting, cutting, and cleaning for each and every X Pipe. With each X Pipe kit, the fabricator can immediately jump to the welding and therefore can spend more time putting their own finishing touches on each and every weld.
