How to Choose The Best Exhaust Pipe Expander Tool Set

Before we get to the reviews, let us talk about the things that should be considered when choosing a pipe expander for yourself. You should always do your research to find the best product for you.

Here are the things you should check:

Size Compatibility

When browsing the options for pipe expanders, you will notice that pipe stretchers have a range of diameters they can work with. The diameter of an exhaust pipe of the vehicle you will be working on must fall within this range, or else the expander will not work.

If you are a mechanic who is likely to work on multiple cars with different exhaust pipe sizes, consider getting an expander kit. Such kits come with several expanders of different sizes, from small to medium to large. So, no matter the vehicle you have, it will work.

You could also try getting universal expanders if you are unwilling to get a kit. Universal expanders can fit the most common vehicles.

Feature Compatibility

Spend some time reviewing the key specifications of the expander you are considering to evaluate if it will be a good fit for the type of vehicle and exhaust pipe you have. For instance, some pipe expanders are durable enough to work with stainless steel pipes, while some are not.

So, you should always check these intricate details to find the best tool for the job.


Take a close look at the materials a pipe expander is made with. This will reflect the quality of performance and durability you will get. An easy way to know if a specific pipe expander is good is to check if it meets the performance standards.

You should also take the build quality and precision into consideration, as both will impact the performance. Lastly, check if the expander can tolerate impact, heat, exertion, et cetera.

Brand Value

I will admit that sometimes, we come across hidden gems from lesser-known brands. But brand value exists for a reason. A reputed brand name is an indicator that the product you are buying will perform at least moderately well.

Other than that, well-known brands also offer a better warranty, free servicing, customer loyalty benefits, etc. So, look for products from brands that are popular in the community.

Due to the aluminum make, some may argue that this set is not eligible to be used with steel pipes. However, that is not true as the kit works perfectly with stainless steel pipes. This is a testament to how durable the individual parts are.

Our first pick for the best exhaust pipe stretcher kit has received rave reviews from DIY custom exhaust makers.

FAQs About Exhaust Pipe Expander Tool Set

1. Can I Expand Pipes Without Heating Them Up?

Ans: Yes, you definitely can. Heating may help with tougher materials, but it is not an absolute necessity for all exhaust pipes.

2. What Materials Are Exhaust Pipes Made Of?

Ans: Because the exhaust pipe is exposed to very high heat and vibrations, the materials used are those that can withstand these with no problem. Such materials include stainless steel, carbon steel, cast iron, aluminized steel, and other alloys.

The durability, resistance, and hardness of the pipes depend on the type of material.

3. What is The Job of a Tailpipe Expander?

Ans: A tail pipe expander is used for increasing the length of a pipe, maintaining equal proportions and the same diameter.

4. Why Do You Need an Exhaust Pipe Expander?

Ans: Exhaust pipes, particularly custom-made ones, do not always fit well. Very often, the mufflers for exhaust pipes are manufactured by a different company and do not properly fit. An exhaust pipe expander can expand the diameter of the pipe to ensure it fits well and can accommodate the muffler.

5. Can I Expand Galvanized Pipes?

Ans: This depends on the model of expander you are using. If the galvanized pipe is too thick, it may strip the threats of your expander tool. So, be cautious if you are trying this.


With the best exhaust pipe expander in your toolset, you can repair, expand, and add accessories to pipes as needed. While it may seem like a very specific tool applicable for niche jobs, in reality, these tools come in handy in many different situations. Just trust us and get one, and you’ll see.
