Universal MeshInterlock Flexible Exhaust Bellows — 1PC (Inlet diameters: 51 / 63 / 76 mm) Key benefits Smoothes exhaust flow: the flexible bellows absorb movement and reduce stress on rigid sections, helping maintain a more consistent exhaust path and supporting engine performance. Improved power response: designed to minimize exhaust backpressure fluctuations, contributing to steadier exhaust flow and potential improvement in power delivery. Durable and weatherresistant: mesh interlock construction resists corrosion, is waterproof and dustproof, and offers strong impact and weather resistance for long service life. Convenient venting: includes an exhaust port to make routing and venting more practical during installation or maintenance. What makes it stand out Mesh interlock design combined with superflexible bellows for flexibility without sacrificing strength. Available inlet diameters of 51 mm, 63 mm, and 76 mm to fit common exhaust pipe sizes. Sold as a singlepiece unit (1PC) for straightforward replacement or integration into custom systems. Function and performance Function: provides a flexible connection in exhaust systems to accommodate thermal expansion, engine movement, and vibration while maintaining exhaust integrity. Performance: engineered to be corrosionresistant, water and dustrepellent, and able to withstand impacts and weather exposure for reliable operation over time. Compatibility and sizing Universal fit for exhaust systems using 51 mm, 63 mm, or 76 mm inlet diameters. Intended as a flexible coupling between compatible exhaust components; confirm pipe inner diameters match the listed sizes before . Practical use scenarios Replacement of a worn or damaged flex pipe on a car or light truck exhaust where a flexible, corrosionresistant joint is required. Custom exhaust fabrication for performance or race vehicles where a flexible bellows section reduces stress on welds and rigid pipes. Marine or outdoor equipment exhaust systems that need waterproof, dustproof, and weatherresistant flexible coupling. What's included 1 piece meshinterlock flexible exhaust bellow (select size: 51 mm, 63 mm, or 76 mm inlet). Notes Verify the inlet diameter needed for your system prior to installation. Intended as a universal flexible exhaust coupling; compatibility depends on matching pipe diameters and installation method.
