Exhaust systems have become increasingly performance-enhancing, durable, and stylistic over the years. However, they’re kind of a basic upgrade for most people and there’s no need to get worked up thinking about it.

But that doesn’t mean that it’s not worth looking into. In fact, if your current system is losing compression and you don’t give it an upgrade, you could be storing up problems for yourself in the future.

Other than that, well-designed mufflers look pretty cool and really help the tone of your engine, especially if they’re of a different size than the standard ones. Such an upgrade can breathe new life into your ride and make it an even more enjoyable experience.

We’ve researched exhaust systems from some of the top-rated brands and narrowed down the list to the 10 best on the market and listed them below.

Frequently Asked Questions (FAQ)

What are the best exhaust systems?

What are the different exhaust systems?

  • Vertical Exhaust Systems These are the most common type of exhaust systems installed in homes simply because they are the least expensive. This system vents exhausting warm indoor air straight outside, usually through an overhang or vent in the roof.
  • Horizontal Exhaust System These are also common because they’re a bit less expensive than the others typical systems. This system vents warm indoor air outside through the attic space, and then the heat exits through the ridge vents in the roof.
  • Geothermal Heat Pumps These heat pumps are used to both heat AND cool your home for maximum efficiency. The system pulls warmth from the outside and pushes it through an air-to-air heat exchange system before sending it into the home. Note that when used for this purpose, it can also be referred to as an Air Handler.

Which is better flowmaster or MagnaFlow?

Flowmaster and MagnaFlow are among the most competitively priced mufflers on the market. While Flowmasters are highly popular, MagnaFlow mufflers carry an excellent reputation for being top-notch, quality products that are reasonably priced.
