One of the most obvious and important parts of any exhaust system is the muffler. The muffler works like a gun silencer to quiet your exhaust note. Basically, the muffler uses a series of baffles and ports to reflect the acoustic waves around the muffler chamber, and they cancel each other out, quieting the exhaust significantly. Because the exhaust gasses do not flow through in a straight line, the muffler is a source of airflow restriction, which is why you want to install a muffler designed to move the gasses through as efficiently and as quickly as possible. The Flowmaster muffler is one such design. Like all Flowmaster exhaust components, the Flowmaster muffler is designed to reduce the pressures that it takes to move the gasses through, and that translates to more power. The Flowmaster muffler is designed for a wide range of applications, but they are most at home on powerful automobiles. You can gain some fairly significant horsepower with a Flowmaster muffler, and they also sound amazing. Every Flowmaster muffler has a deep rumble that can really get you some attention no matter where your tach is positioned. Car hobbyists deserve excellent sales help when purchasing good quality car or truck parts. Thus, we established a round-the-clock information and support desk to support you with your requests. To sweeten the deal, we provide 100% free shipping on every order $50 or higher. If you spot a lower price elsewhere, call us - we will meet or beat any legitimate auto part price.

Flowmaster Muffler Review

  • Price 5
Overall Rating 4.8

Trading your stock muffler for an aftermarket muffler is one of the best things that you can do to give your vehicle a more personalized touch. Choosing the right one for you can be pretty tough, though, as there are so many to choose from in the market. With that said, a Flowmaster muffler is one of the better options out there. Let's see just how good it is.

Features
  • Composed of stainless steel
  • Oval-shaped
  • Specifications: 13 in. length, 9.75 in. width, 4 in. height, 19 in. overall length
  • Uses a single-center inlet and dual offset outlet configuration
  • Uses the brand's patented "Delta Flow" technology
  • Boasts of two-chamber internals for superior power and a more aggressive sound
  • Sports a sleek black finish
  • Comes with a Flowmaster lifetime limited warranty

We tested the product in our Chevrolet Silverado 1500. Below are our observations:

The Good
  • Installing it was a breeze.
  • It made our hulking Chevrolet Silverado 1500 even more badass. The aggressive sound produced by the Flowmaster muffler complemented the image of our vehicle.
  • The Delta Flow technology is the real deal--it helped improve the performance of our Chevrolet Silverado 1500. Throttle response became noticeably better after installing the Flowmaster muffler. Those looking for an extra kick would surely appreciate this.
  • The product features a case that's smaller than those used by most other mufflers. This allowed our vehicle to have greater ground clearance. Two thumbs up for this as we don't have to worry (that much, at least) about it getting damaged!
  • The sleek black muffler added to our vehicle's style points. It's subtle, but it's a very welcome bonus.
The Bad
  • While we found the more aggressive sound rather appealing, there's a chance that others won't. You may not like it yourself. It's more of a taste thing, after all.
  • If you're looking for a muffler that's really quiet, then you're looking at the wrong product. There are numerous other mufflers that do a better job at, well, muffling sound. Still, the Flowmaster muffler isn't so bad at it.
The Verdict

The Flowmaster muffler may not be the perfect muffler for everyone. However, it does have a lot of good things going for it. It's functional, stylish, and rust-resistant, after all. On top of those, installing it wasn't a real chore. Don't forget the lifetime warranty, too. So yeah, it's definitely a good buy with all of those in mind.
