Exhaust Clamp Buying Guide

When the exhaust clamp of your vehicle wears out or gets broken, you will definitely need to buy a new one. There are numerous types of exhaust clamps in the market today, and it can be daunting to get the right one. Below are some of the things you need to check before you purchase an exhaust clamp:

#Size of the Clamp

The size of the clamp is measured from the inside diameter. You need to find the worn out clamp first before the purchase so that you can know the exact size. Exhaust pipes differ in sizes depending on the make of the vehicle and year of manufacture. You can also look at the manual of your car for the recommended size. A larger exhaust clamp will leave the pipes loose, thus causing exhaust leaks.

#Style of the Clamp

The next thing to check is the style of the clamp. Different clamps in the market are made with different styles for multiple uses. Ensure that you know the exact style that will work for the exhaust pipe connections. You can also check the car manual or contact the aftermarket supplier to enquire about the style if you are replacing an aftermarket clamp.


The circumference is the area all-round the exhaust pipe. Ensure that the exhaust clamp fits well around the pipe for proper connections. It should not be too large since it will be loose; neither should it be too small for it will not cover the entire area. Installing the wrong exhaust clamp size can cause problems in the exhaust system, which may later lead to complete replacement of the entire system.

#Materials Used

Another important thing to determine is the materials used to make the exhaust clamp. The clamps will, at times, get into contact with water or in very harsh environments. Most clamps are made of aluminized and stainless steel. Ensure that the exhaust clamp is resistant to rust and corrosion. It should also be made with robust and strong material to prevent it from wearing out fast. The type of material used to make the exhaust clamp will determine its durability.

#Ease of Installation

When buying an exhaust clamp, and especially if you are a DIY, it is important to get one that is easy to install. This will not take you too much time to connect the two exhaust pipes.


Cost is also a major thing to consider. Look for an exhaust clamps that fits your budget, but it should not be at the expense of quality. There are exhaust clamps made with high-quality materials and still sold at a fair price. You can also look for some popular brands with low prices since you will be sure of good quality clamps.

  • Put on your work gloves and safety glasses
  • Disable and loosen the exhaust clamp and remove the hex nuts from the U-bolt
  • Place the saddle on the connection of the exhaust pipe
  • Slide the U-bolt in the saddle and then thread a hex nut on the legs of the U-bolt. Avoid tightening the hex nuts at this point.
  • Apply pressure on the connection of the exhaust pipe and make sure that the connection is seated perfectly
  • Choose a socket with the same size of the hex nuts and attach it to the ratchet
  • Set the ratchet for tightening
  • Slide the socket to the hex nut and tighten it till it’s tight
  • Repeat the process to tighten the other hex nuts
