What is a Flex Pipe?

A flex pipe, also sometimes known as a flex coupling, is a section of bellowed steel, which as it’s name implies, is designed to flex or bend. The purpose of a flex pipe in an exhaust system is to absorb or relieve vibrations from the engine and from the motion of the vehicle and prevent other more expensive components from being broken or cracked. Some parts of the exhaust system such as exhaust manifolds, (which are often made of cast iron) are brittle and easily break. Flex pipes prevent these components from being exposed to excessive stress. Flex pipes are NOT intended to make bends such as those found in tailpipes. Such use is not covered by warranty and is likely to damage the flex.


How to use this flex pipe

This flex pipe is designed to slide over your exhaust pipe in the size shown above (i.e. 2" flex pipe will slide over 2" exhaust pipe). It must be welded, and cannot be clamped. In most instances, it is designed to replace an existing failed flex pipe. The longer the flex pipe, the more flexibility you will have. It is meant to slide over your exhaust pipe, never inside. It may not be welded directly to an exhaust flange, but must be welded to exhaust pipe, which is then welded to the flange. Damage may result if used incorrectly, such as, but not limited to: using the flex pipe to replace a bend, road damage, overheating, missing hangers, broken motor mounts, etc. It is not designed to be used in such a way, but to relieve vibrations from the engine and other motions of the vehicle. It is not meant to be installed near the engine as it will overheat.


Anatomy of a Flex Pipe

A flex pipe is made up of a variety of components. These components may vary somewhat from manufacturer to manufacturer, but typically are made up of steel accordion type bellows. These bellows are often covered with a braided steel reinforcement, which prevents the flex from stretching too far and protects it from damage. Some will also contain an inner braided steel covering or a solid, floating insert, which functions to reduce exhaust turbulence. The ends of the flex usually have a solid steel shield, which joins the braided covering and reinforces the connection to the exhaust pipe. In the case of replacement flexes, they may or may not have pipe extensions which allow it to be easily welded or clamped into and existing exhaust system. The flex pipes are rated by diameter and length from end to end, not including pipe extensions. Pipe extensions are approximately 2" long, adding approximately 4" to the total length on the unit.


Differences in Flex Pipes

Flex pipes can be made from a variety of different materials and can also differ in their construction techniques. Some companies use ordinary steel, which can rust and corrode and/or may use aluminized steel (ordinary steel with an aluminum-based coating). These materials typically do not last very long as compared to stainless steel. Additionally, many companies will crimp the fittings together, which allows water to become trapped in the crimped joint, encouraging corrosion. Some flex bellows are formed as a continuous helix, which can create exhaust turbulence and, in general, indicates that poor construction techniques are used. Some companies have a loose braid pattern on the outer and inner coverings, which allows the flex to stretch too far, causing premature failure. There can also be variations in the gauge of materials, as well as the exact type of materials that are used, which has a significant influence on the price and longevity of the joint as a whole.


Bear River Flex Pipes

We do not compromise on our flex pipes, which are made entirely of stainless steel. We use 304 stainless to form the non-helical bellows as well as the braided reinforcements. We use a tightly woven braid pattern for greater strength. Most of our flex joints also have an inner braid and are built from heavy gauge materials to last for as long as possible. We believe that you want the best product for your money and that is why we do not offer second rate products.


Warranty

We are so confident in the quality of our flex pipes, that we offer a guarantee that our flex pipes will not fail do to corrosion, cracking, or splitting for 5 years/50,000 miles, whichever happens first. This warranty does not cover damage that may be the result of improper use, including, but not limited to: using the flex pipe to replace a bend, road damage, overheating, missing hangers, broken motor mounts, etc. If for any reason our flex joint fails under normal use, we will replace it free of charge. Our warranty does not cover labor costs or other installation costs. It also does not cover any incidental or consequential damages.

Due to issues we have been having with the United States Postal Service, namely lost or misdirected packages, no accountability for lost or misdirected packages, the lack of a good tracking, and the lack of customer service when a problem does arrise. We are encouraging all buyers who wish to receive their items in good time with minimal hassle to select UPS as the shipping method. UPS has shown that they are more consistent on their delivery times, and their tracking system is much better, and the incidence of lost packages is much lower.

We are open from 10AM - 5PM MST Mon-Fri. We are closed on most major US holidays. If you have a question please use the contact seller link. We do NOT accept orders over the phone. _gsrx_vers_526 (GS 6.6.6 (526))
