How To Cut An Exhaust Pipe With A Reciprocating Saw?

A reciprocating saw is a handy tool to have around, whether you’re a professional carpenter or just doing some DIY projects around the house. But when it comes time to cut an exhaust pipe, many people don’t know how to do it properly.

In this blog post, we’ll show you how to use a reciprocating saw to cut an exhaust pipe like a pro. Keep reading for tips and tricks!

How To Cut An Exhaust Pipe With A Reciprocating Saw:

Step 1.

Prepare the exhaust pipe for cutting. Using your hands, bend back the rubber portion of the exhaust so you can access the metal part without it flapping around.

Step 2.

If there is any wiring in the area that you want to cut, remove the wire by gently pulling it through until you get to where it starts. You can then safely cut right next to this section of wire without accidentally cutting into it while making your cuts on the pipe.

Step 3.

Clamp off any other wires or electrical components that are near where you’ll be working once they’re out of the way and fully exposed. This keeps them from being damaged as well as keeps you from accidentally cutting them.

Step 4.

Cut the pipe at its base closest to the exhaust manifold using an upward motion. The exhaust will start to fall down after you’re done cutting, so hold it up with one hand while making your cuts. If you just pull the saw directly out of the exhaust pipe, it may create some sparks that could burn you or someone nearby.

Step 5.

After you’ve made all cuts above where the rear flange is, cut through this crucial part of the pipe so it falls down completely. Use a downward motion for this rather than pulling away from it as you did before.

Step 6.

Dispose of any pieces of still attached old parts in accordance with local regulations and practice safety precautions when doing so. By following these steps, you can cut an exhaust pipe with a reciprocating saw very easily and safely. Cutting this type of material isn’t too difficult with the right kind of saw and preparation.

Safety Tips:

Keep all bystanders away from the area you’re working in.

Make sure you have proper ventilation and breathing protection when cutting any kind of material, including exhaust pipes.

Always wear protective gear such as safety glasses or goggles.

Be aware of any electric currents you might come in contact with.

Don’t wear loose clothing that could potentially get caught on the saw if it kicks back during use.

Don’t make your cuts too deep or you could damage other components around where you’re cutting.

For best results, cut only partially through the first time to create a groove for subsequent passes. This way, the remaining material doesn’t have anything to grab onto as you finish up your work and can fall away more easily instead of hanging up on something you’ve already cut through.


What are the dangers of cutting an exhaust pipe with a reciprocating saw?

Cutting through metal pipes creates sparks and can produce dangerous fumes, so it’s important to work in a well-ventilated area and wear proper protection when using this type of saw.

Is it safe to cut an exhaust pipe with a reciprocating saw?

Yes, as long as you follow the safety precautions mentioned earlier. If you don’t, there is potential for burn or electric shock risk if the hot exhaust hits bare skin for instance.

What are some tips for avoiding mistakes when cutting an exhaust pipe? 

Don’t cut too deeply into the pipe in one pass. This way, if you do make a mistake or something goes wrong with your saw, there’s less chance of it getting stuck and causing injury.

How should I prepare to safely cut an exhaust pipe?

Make sure you have proper ventilation in the area where you’re working. Also, remove any loose clothing that could be caught in moving parts if necessary.

Can I cut both metal and PVC pipes with a reciprocating saw?

Yes, but when using these types of tools always follow safety precautions outlined in your owner’s manual to avoid the risk of burn or electric shock when coming into contact with fluids that may spurt out during use.
