How To Install Exhaust Band Clamps

Unless you have to supercede the entire exhaust organization, bones maintenance of your vehicle's exhaust system can be done with just a few hand tools and the right parts. Just what parts are the right parts? There all kinds of different components in the exhaust. The big pieces—mufflers, pipes, and catalytic converters crave cut and welding in near cases, and so you may not desire to tackle that yourself (though you certainly can). These major components are not part of the general maintenance authorities, which includes frazzle gaskets, exhaust clamps, and frazzle hangers.

Eventually, these parts volition fail, usually earlier the major components. Gaskets and hangers are the almost mutual replacement parts for typical exhaust system, hangers are usually replaced equally function of servicing the other ii components. There are several types of each; this commodity should assist you lot make heads or tails of what y'all take and what you demand. We will cover gaskets in some other article, this commodity is focused on hangers and clamps.

Exhaust Hangers

Factory hangers range from vehicle-specific to universal. You may be surprised to find out that almost vehicles use universal-fashion hangers as opposed to the vehicle specific ones. This is because it is much easier (that ways cheaper) for an car manufacturer to just apply an off the shelf parts for the frazzle than spend hundreds of hours developing and manufacturing a subclass and hanger for one motorcar model. There are some cars that use very specific hangers, this was a common exercise in the late 1980s to early on nineties.

The old style of hanger, which is yet used in most universal exhaust kits, is the strap and U-bolt hanger. They work.

Nigh modern vehicles utilize a readily-replaceable hanger system that consists of two pegs and a rubber isolator bushing. The pegs expect like exaggerated arrows, the large cone shaped tip passes through the isolator, but can't slide back off. These isolators append the exhaust from the chassis, while arresting vibrations so the frazzle system is quiet and does not rattle. These accept become the most popular style of hanger. One peg is welded to the tubing, while the other is typically welded to a pocket-sized bracket that it bolted to the chassis itself. The positions are vehicle-specific, merely the isolators are mostly universal. There are different sizes to match the factory isolator.

Most newer vehicles use these safety isolator style hangers. They are easy to replace and readily bachelor.

Older vehicles utilise the other mode of universal hanger. These are a combination stamped steel brackets with a belted rubber strap. There are many unlike shapes and sizes of these strap hangers, many are brand and model specific, only they are still universal because they comprehend a wide range of vehicles and can exist used in other applications. The truly universal strap hanger is a single strip of safe with a several equally-spaced holes in information technology (this is the part that bolts to the chassis), and a unmarried metallic bracket on one end which is designed to be secured using a U-commodities frazzle clamp. When changing these manner of hangers, it is a good thought to replace the clench too.

Exhaust Clamps

At that place are numerous mode of exhaust clamps, and the blazon that your vehicle's exhaust arrangement uses depends on the car. The main types are brawl and socket, U-bolt, flat band, and V-band clamps. Each have their place in the exhaust system and you may detect 2 or more than styles of clamp on your mill organization.

U-Bolt

This is the most common blazon of frazzle clamp , fifty-fifty though it is the worst one. And then many aftermarket exhaust systems use these types of clamps, even manufactory systems have used them. They are cracking, they are certainly functional and useful for hangers and sideslip-fit pipe connections. They get the job done when properly installed. The problem arises when you need adjust or remove a section of the exhaust for service, such as drivetrain or rear suspension repairs. The minor diameter of the clench crimps the pipes together, so y'all can twist them, but usually you tin't actually separate the tubes. If you lot don't get the clamp tight enough to crimp the tubes, they leak.

U-bolt clamps do work, but they are non really reusable, and they beat the pipage, and then information technology is really had to take them autonomously for service. Not to mention the nuts tend to rust, locking them together forever.

Ball and Socket

This is not quite a clench, but too not a flange. But like it sounds, there is a rounded ball terminate that fit within a flared socket end of piping. The two halves are compressed together with a two or three-commodities ring on either side of the joint. This is a gasket-less connection that is quite common on factory exhaust systems, peculiarly used betwixt the exhaust manifold and the catalytic convertor . The true cat is a service slice, so they have to be hands removable. The ball and socket can be reused over and over again, so it works really well. These can be bought as weld-on sections for custom exhaust as well.

This is 1 type of ball and socket, information technology is a hybrid betwixt a clamp and brawl and socket, with a sealing ball clamp in the middle.

This is the most common type of ball and socket. sometimes the factory will utilize a compressible donut to seal the joint, but commonly it is simply metallic on metallic.

The two halves fit together similar this and so are compressed together with the two nuts.

Band

The band clench is a wide strap of metal, typically stainless or mild steel, which wraps around the frazzle pipe joint. These come in two subtypes, a pre-formed ring or a flat strap that y'all wrap effectually the pipe and bolt together. The pre-formed blazon is now more commonly used in college-end aftermarket exhaust systems using skid-fit, whereas the flat band strap clench is sold a "sealing clamp", designed for use in butt-joint seams. The biggest do good of this style is ease of apply, they are relatively cheap, and are reusable without dissentious the pipes. You tin can easily remove the system for service and reinstall everything without cutting anything.

This is a band clamp. These are available in narrow and wide. Wide clamps are designed to seal two butt-jointed pipe together, whereas this narrow clamp works for sideslip-fit pipes. These are easily separated for service, which is why they are more popular than the u-bolt clamps.

Five-Band

If your last name is Warbucks or Rockefeller, so y'all can afford V-band clamps . All jokes aside, these things are really expensive, easily fetching $20-30 each (and much more than), just if y'all have a high-end vehicle with a turbo, they are worth it. Typically these clamps are used on turbo exhaust systems, considering they are like shooting fish in a barrel to piece of work with, seal better than annihilation else, and await good. Each clench consists of ii machined interlocking rings that get welded to the pipes, and a large outer ring that sandwiches the two rings together for a perfect leak-complimentary seal. If you are edifice a custom exhaust system and you may need to remove information technology afterward, or want a loftier-end await, dropping a few hundred bucks on some stainless steel Five-band clamps may be worth the price. Is information technology overkill for a daily-driver Accord or Saturn? Yep. Does it look absurd anyhow? Admittedly.

The V-band clench is the best of them all. they are serviceable, cocky-sealing, and they look amazing. Note the two ring halves, they interlock to provide the all-time seal.

In one case welded to the pipes, the V-band clamps lock in place, and yous but wrap the clench ring over and commodities it down.

Servicing your vehicle's exhaust system is not the most glamorous task. If you have a worn out exhaust hanger or busted exhaust clamp, fix information technology equally shortly as possible, otherwise you could exist shelling out big bucks replacing the entire system later on yous drive over it on the throughway.
