Ultimate Guide on How to Choose the Best Exhaust Repair Tape

There are certain factors that you’ll have to focus on while picking the right repair tape for yourself. In this section, we’ll discuss these factors in detail, so you know what to look for.


You won’t get good service from a repair tape if it isn’t compatible with the type of crack you’re trying to seal. So, you better check whether the tape is suitable for sealing the specific area you want to fix.

Time Taken

You can’t fire up your car right after applying the tape because most tapes take some time to cool off after application. Tapes that take less time to cool down and seal are mostly better, but they’re likely to cost more.


This is one of the most crucial factors that you need to keep an eye out for. The exhaust of your vehicle will become heated pretty soon, and that heat will retain as long as the vehicle is turned on.

If the tape fails to handle that temperature, then it will come off, and you’ll have to seal it again. This is why you should look for heat-resistant tapes that can handle any vehicle’s exhaust easily.

Ease of Usage

You don’t want to purchase a product that takes a whole day to apply, especially because there are tons of products on the market that are easy to apply. We suggest looking for products that can be used in one step.


Products from a quality brand can beat non-branded products by a mile. This is why we highly recommend looking for products that are manufactured by good brands. LLPT, FiberFix, 3M, etc., are amazing brands that you can rely on.


Last but not least, you must consider the price. We certainly don’t recommend going all out on a product that offers everything. Rather, we encourage you to save money by getting products that can provide exactly what you need.

  • Compatible Material: Can be applied on any surface
  • Temperature Rating: Up to 350-degree Fahrenheit

The Newtex Z-Flex is considered the best repair tape for exhaust pipes by many because of the amazing features they provide. This is essentially aluminum foil that was coated with pressure-sensitive adhesive for heat resistance and insulation.

While most tapes come with a 2” width, this comes with a 1.5” width, making it a much better choice for sealing smaller cracks. Installing this is very easy as well. All you need to do is remove the tape backing and apply it on a dry and clean surface. If the crack spans across a long area, just wrap the tape around that area.

Once you’re done wrapping, you’ll need to seal the final wrap with a cable tie clamp or a worm gear clamp. This doesn’t take any time for curing.

Frequently Asked Questions About Exhaust Repair Tape

1. How to Make a Good Seal?

Ans: To ensure the seal is good and won’t fall off after a few days, you need to clean the area first. Once the area is clean, make sure it’s completely dry. If there’s even a bit of wetness there, the adhesive won’t stick properly.

After the area is completely clean and dry, apply the heat-resistant adhesive tape of your choice. This will make sure that the tape lasts a long time.

2. Are Products that Require Time to Cure Better than the Ones that Don’t?

Ans: Not really. The products that require time to cure usually take that time to get harder. These tapes harden like steel and offer a solid surface that’s not easily distinguishable.

On the other hand, the ones that don’t require curing time are generally softer. However, both are viable options, and which one you’ll choose depends on personal preference.

3. How Much Time Should You Wait After Applying a Tape?

Ans: The time required for the tape to cure and settle is addressed on the packages of the tapes. While you’ll need to wait around an hour with some of them, you won’t have to do so with some products.


Now that you know what each of the products is offering, hopefully, it’ll be easier for you to pick the best exhaust repair tape for yourself.

All the products listed here are amazing, and we guarantee that you’ll have a great time using them. Just focus on what they’re offering and pick the one that suits your requirements.
