If you are here to find out the cost of muffler deletion, you have come to the right place. In this guide, I have explained how much it costs if a professional shop does it and the cost of doing it yourself. 

Take into consideration that muffler deletion is a big decision. That’s why I have also mentioned the pros and cons of deleting the muffler so you can make a decision that suits you and does not result in regret and loss of money as well. 


How Much Does a Muffler Delete Cost?

A muffler delete can cost anywhere from 10$ to 250$ depending upon many factors, such as paying a professional to do it or doing it yourself. Below, I have mentioned the cost for both:

Muffler Delete Cost at a Professional Shop

A muffler delete at a professional shop can cost 100$ to 250$. Depending upon vehicle make and model, the quality of the job, and the location of the shop. The price includes both labor and material charges that will be used. 

DIY Muffler Delete Cost

A DIY muffler can cost as low as 25$ to 80$, considering you have all the required tools. All you need to buy is pipes, clamps, and hangers. If you already have the material, the cost will be almost nothing. 

If you do not have the cutting and welding equipment, the cost will increase significantly and would cost even more than a muffler delete job by a professional shop. So, it does not even make sense from a cost perspective. 

Note: Deleting the muffler by yourself can be unsafe since it requires expertise and experience. If you do not have the skill set to do it, I recommend you let a professional handle that. 


Pros and Cons of Muffler Delete

Deleting the muffler is a modification that comes with both advantages and disadvantages. As mentioned before, you need to consider these pros and cons before you make a decision. The pros and cons are:


  • Better exhaust sound
  • Performance gain
  • Reduced weight (Mufflers are heavy)
  • Less expensive than aftermarket exhausts


  • Legal issues
  • Warranty may void
  • Increased emissions
  • Reduced fuel efficiency
  • Reduced resale value of the car
  • Louder exhaust can be uncomfortable during long drives



Q. Is a Muffler Delete Worth It?

A. If it’s legal in your city, you can go for it. I do not feel like it’s worth it since, after a certain period, the loud exhaust gets annoying for me. 

Q. Is a Muffler Delete Illegal

A. It depends upon where you live. They are allowed in some states and cities and illegal in others. 

Q. Does a Muffler Delete Increase Horsepower?

Yes, in some vehicles, deleting the muffler can slightly increase the horsepower. Removing the muffler decreases the back pressure, which can result in engine performance due to the engine expelling exhaust gases freely. But engines are tuned for a certain amount of backpressure for optimal performance. An increase in backpressure can damage the engine in the long term. 

Q. Can You Install a Muffler Without Welding?

Yes, you can install a muffler without welding. You can use clamps and exhaust hangers instead of welding. Keep in mind that installing a muffler without welding is easy and less permanent, but welding is considered the most durable and leak-proof method. So if you want a permanent method of installing the muffler, it’s better to go with welding.
