There are many different shapes and sizes of these strap hangers, many are brand and model specific, but they are still universal because they cover a wide range of vehicles and can be used in other applications. These are a combination stamped steel brackets with a belted rubber strap. Older vehicles use the other style of universal hanger. They are easy to replace and readily available. Most newer vehicles use these rubber isolator style hangers. There are different sizes to match the factory isolator. The positions are vehicle-specific, but the isolators are generally universal. One peg is welded to the tubing, while the other is typically welded to a small bracket that it bolted to the chassis itself. These have become the most popular style of hanger. These isolators suspend the exhaust from the chassis, while absorbing vibrations so the exhaust system is quiet and does not rattle. The pegs look like exaggerated arrows, the large cone shaped tip passes through the isolator, but can’t slide back off. Most modern vehicles use a readily-replaceable hanger system that consists of two pegs and a rubber isolator bushing. The old style of hanger, which is still used in most universal exhaust kits, is the strap and U-bolt hanger. There are some cars that use very specific hangers, this was a common practice in the late 1980s to early nineties.

This is because it is much easier (that means cheaper) for an auto manufacturer to simply use an off the shelf parts for the exhaust than spend hundreds of hours developing and manufacturing a bracket and hanger for one car model. You may be surprised to find out that most vehicles use universal-style hangers as opposed to the vehicle specific ones. Exhaust Hangersįactory hangers range from vehicle-specific to universal. We will cover gaskets in another article, this article is focused on hangers and clamps. There are several types of each this article should help you make heads or tails of what you have and what you need. Gaskets and hangers are the most common replacement parts for typical exhaust system, hangers are usually replaced as part of servicing the other two components. These major components are not part of the general maintenance regime, which includes exhaust gaskets, exhaust clamps, and exhaust hangers.Įventually, these parts will fail, usually before the major components. The big pieces-mufflers, pipes, and catalytic converters require cutting and welding in most cases, so you may not want to tackle that yourself (though you certainly can). But what parts are the right parts? There all kinds of different components in the exhaust. Unless you have to replace the entire exhaust system, basic maintenance of your vehicle’s exhaust system can be done with just a few hand tools and the right parts.
