What is the purpose of a flex joint in an exhaust system?

A flex joint is designed to absorb engine movement and vibration. This helps to prevent stress from being transferred to other parts of the exhaust system, reducing the risk of cracks or leaks.

What does the interlock liner do?

The interlock liner is an internal component within the flex joint. It helps to create a more secure seal and can add an extra layer of durability, further preventing exhaust gases from escaping.

Can this flex joint be used in California?

No, this flex joint is not CARB approved and cannot be shipped to California due to emissions regulations.

About this part

Product Details

This Stainless Bros flex joint measures 1.75 inches in diameter and has an overall length of 4 inches. It's constructed from 304 stainless steel and includes an interlock liner, which helps to prevent exhaust leaks and adds durability. Flex joints are used in exhaust systems to absorb engine movement and vibration, preventing stress on other exhaust components.

The 304 stainless steel construction means this part is well-built and resistant to corrosion, which is important for exhaust components exposed to heat and moisture. The interlock liner is a notable feature that adds an extra layer of protection against leaks, especially under flex. This makes it a solid option for custom exhaust builds or repairs where flexibility is needed.
