Your source for detailed Flowmaster exhaust comparison
Considering a new Flowmaster muffler? Among many factors influencing your decision, size and design are the two greatest influences on a mufflerās sound quality and volume. While a chambered muffler will create a raspier sound, laminar or āstraight-throughā muffler designs tend to offer a smoother tone. Either way, the larger the muffler, the quieter the sound that is produced. Here in our comparison guide, weāll look at the loudest Flowmaster muffler, the quietest, and others available in-between. Weāll help you decide on the best fit for your ride, with advice you can trust from experienced experts, so read on, absorb and follow up with questions! We want to help you make a well-informed decision, and whatever you decide, RealTruck has your new Flowmaster.
If youāre not familiar with the brand, you should know that Flowmaster mufflers are the gold standard for controlling the sound of a vehicleās engine. Below in our Flowmaster muffler chart, we look at Flowmaster, loudest to quietest. We compare various factors in their popular models, including the exterior and interior sound levels you can expect to experience with each, whether itās made with stainless steel (and a limited lifetime warranty), Delta Flow chambered technology for a distinctive performance growl, Laminar Flow (straight-through) technology for reduced interior turbulence or Cool Shell (heat reduction) tech to keep the muffler cooler, particularly when itās mounted near fuel systems. We also make note of recommended applications for use.
Flowmaster places each of its mufflers into one of three sound-level categories: Aggressive, Moderate and Mild. Aggressive mufflers are the loudest, offering significant exterior sound with a noticeable concurrent level of sound and vibration within the vehicle. While many Flowmaster mufflers in this category are indeed street legal, theyāre also considered racing-level mufflers. Within the Moderate category, which is popular with truck owners and those with V6 or V8 engines, users can expect to experience a moderate level of exterior sound, with minimal interior sound and vibration. In the third category known as Mild, drivers will experience lower sound levels which resemble stock or factory-level volumes, while adding some distinctive tonal character.
With several muffler options at each Flowmaster sound-level rating available now and shipping free to the lower 48, RealTruck makes it easy to find what you need. Within each Flowmaster category, your muffler options at RealTruck include the following:
