Stainless Bros 3.0in x 4in OAL 304SS Flex Joint w/ Interlock Liner

This is a 3-inch diameter by 4-inch overall length flex joint from Stainless Bros, made from 304 stainless steel and featuring an interlock liner. Flex joints are used in exhaust systems to absorb engine movement and vibration, preventing stress cracks and leaks in the exhaust piping. The interlock liner adds an extra layer of durability and helps maintain exhaust flow even under stress.

Crafted from 304 stainless steel, this flex joint is well-built to resist corrosion and withstand the high temperatures found in exhaust systems. The interlock liner provides a robust internal structure, ensuring the joint can flex without collapsing or restricting exhaust gases. This makes it a solid option for custom exhaust builds or replacing a worn-out flex section.
