Exhaust systems come with mufflers, or not. It all depends on what you plan on doing with your vehicle and the noise levels you want while driving. For racing, you might forgo a muffler all together, after all, what is a battling rooster without its roaring squawk! Bottom line, mufflers are for people that want to either eliminate the sound of their vehicle to the minimum, which provides both comforts during the ride as well as silence to the environment. The other option is a nicely tuned rumbling roar of a muffler, when combined with a great exhaust system can make even the simplest of vehicles sound like a hypercar or a stock racing car, whichever you prefer.
Essentially, when buying a muffler, you buy it together with the exhaust system. However, sometimes you want to create your own design or change a muffler within an already applied system. In this case, you will need to consider not only the muffler design and style but its shape and size and compatibility with your vehicle. Also, for pimped up rides, consider the finish and how it looks as well as performs.

Conclusions
There are many brands and makes for different models and applications. These are the five best performance mufflers for reducing sound to a nice low rumble. They are all stainless-steel parts, so they will provide you with the best resistance to corrosion and provide the highest life cycle.
Things to Consider when Shopping for Performance Mufflers
Mufflers provide noise protection, for both yourself while driving and for the environment. Stainless steel mufflers are the best muffler materials for handling salty atmospheres, especially near coastlines as such, they are more than optimized for dry condition performance.
There are two stainless steel alloys used in these parts, either T409 and T304. The T304 alloy provides better corrosion resistance. If you live in a dry area, you might consider using an aluminized finish which is as good as any stainless-steel finish for those conditions.
Different mufflers for different applications. This opening statement means that you need to match the muffler to what you will perform the most with your vehicle. If you intend to race more than ride, then you need a muffler with fewer baffles, this will provide a superior flow rate and increase your HP and torque. It will also make your vehicle loud, which is really what you want in a testosterone flooded atmosphere.
When buying a muffler, you have two considerations to make in regards to local law enforcement. These are the decibel levels permitted and the emission codes for various toxic substances. California is the strictest in this regard. Just make sure your muffler meets the emission codes. Otherwise, you are risking a pull-over.
Muffler Anatomy
Mufflers basically have one inlet, and one or two outlets with a large chamber between. There are different configurations for different applications as well as ranges from various manufacturers. There are two basic structural design differences:
Straight Through Type
These use a single perforated pipe that starts from one end of the muffler and ends at the other end. The perforations are in place to reduce the high-frequency sounds and displace them into the packing materials.
Chamber/Baffle Type
These integrate a series of angled walls that “bounce” sound waves into each another, this cancels out conflicting sounds and reduces the overall effect to a muted output.
Hybrid Type
These models use both perforated pipes and baffles to provide an optimized noise reduction.
What is the best type?
All of them are good, it’s about measured performance gains as well as looks, in the end, these three systems all work the same, and it’s just a matter of perceptual favoritism to decide which one you like and prefer on your vehicle.
Some Muffler Facts:
- Size counts, the smaller the muffler, the louder it will be.
- High-performance mufflers must be welded or will come with special installation hardware.
- 99% of all Performance Mufflers are not OE fitment ready; you will need to make some modifications.
- Flowmaster is one of the few if the not only company that fabricates direct-fit kits.
When buying a muffler, know this:
- Measure your OEM muffler’s case-length, width, inlet and outlet sizes as well the layout.
- Inlet size corresponds to the size the inlet of the muffler will fit over the exhaust pipe.
