When to Replace Your Exhaust Muffler
If your vehicle’s exhaust system is making loud rumbling noises, it’s probably time for a new muffler. An exhaust muffler muffles the noise from the exhaust gasses leaving your engine. Once it’s damaged or rusted out, it won’t do its job properly.
Signs you need a replacement muffler include:
- Loud, rumbling noises coming from under your vehicle. This indicates holes or leaks in your muffler that need to be repaired or replaced.
- Loss of power or poor engine performance. A faulty muffler can restrict exhaust flow, reducing engine power.
- Rust or damage. If your muffler shows visible rust, dents or holes, it needs to be replaced.
- Fumes in the cabin. If you smell exhaust fumes inside your vehicle, the muffler likely needs replacement. This is dangerous and should be addressed right away.
Replacing an exhaust muffler is not a DIY job for novices. It requires detaching the old muffler from the exhaust pipes, then installing a new muffler and reattaching the pipes. It’s best left to a certified mechanic with the proper equipment, tools and experience. They can also inspect the rest of your exhaust system to ensure there are no other issues.
A new muffler will get your vehicle running safely and quietly again, so you can continue enjoying the open road. Regular exhaust inspections and maintenance will help maximize the life of your new muffler.
How to Choose the Right Exhaust Muffler
Choosing the right muffler for your vehicle is important for performance, sound, and your wallet. ###
First, determine if you want a stock muffler replacement or an aftermarket performance muffler. Stock mufflers typically offer an OEM-level of sound deadening at a lower cost, while performance mufflers generally provide a deeper, throatier sound and may increase power slightly. It depends what’s most important to you.
Next, consider the muffler’s construction. Aluminized or stainless steel mufflers tend to last the longest. Fiberglass packs more sound deadening material but doesn’t last as long. For most drivers, an aluminized or stainless steel muffler with a moderate amount of sound deadening material is a good, affordable choice.
You’ll also need to choose a muffler that matches your vehicle’s exhaust system. The most common types are single in/out, dual in/out, and dual in/single out. Choose the configuration that matches your existing exhaust piping to avoid having to replace more of the system.
Finally, have a trusted mechanic install the new muffler. They have the proper tools, training and experience to remove your old muffler and install the new one correctly. A poor installation job could lead to exhaust leaks, strange sounds, or the new muffler not functioning properly.
With some research on the options and professional installation, you’ll have a new muffler that provides the right sound and performance for your needs and budget. Your vehicle and ears will thank you!
