This Stainless Bros flex joint is a 1.75in by 4in overall length 304 stainless steel exhaust flex coupling with an interlock liner. It provides articulation and vibration isolation in exhaust systems while the interlock liner improves flow consistency. Use it to accommodate thermal expansion and alignment variance; confirm the 1.75in diameter and 4in overall length match your exhaust tubing before fitting.
