We all know mufflers, well…muffle, but less obvious are which mufflers provide the best blend of volume control and heart-pounding tone. Don’t sweat it. We compare Flowmaster’s most popular mufflers to help you find the series that’s best-suited for your ride.
This is the perfect daily driver muffler. The Super 50 Series is tougher sounding at idle and noticeably louder than your ride’s stock exhaust when you stomp on the gas. But don’t worry about excessive noise—while these mufflers sound incredible, they still allow you to have conversations with your passengers. Perfectly aligned plates, known as “baffles” cancel unwanted sound frequency, and let the classic Flowmaster tone shine through. Best of all, Super 50 mufflers keep interior resonance to a bare minimum, for a smooth, performance tone, at any speed.
Looking for a performance growl without a scowl from your neighbors? Well, look no further than 50 Series Delta Flow mufflers. Think of it as a Super 50 Series, but with a bad attitude. 50 Series Delta Flow mufflers have a finely-tuned baffle design that’s sure to give your ride a classic “muscle car” tone, without driving you nuts on the highway.
The Pro Series muffler stands apart from the rest of Flowmaster’s herd with a new, laminar-flow design. Picture two mesh cones, touching tip to tip—that’s all there is to them. There are no baffles to restrict flow, or fiberglass packing to blow out over time. This gives the Pro Series muffler a bass-filled exhaust tone that never changes. Best of all, this muffler has the same volume as the 50 Series Delta Flow, but with a stronger, deeper rumble.
The 40 Series Delta Flow muffler cranks out an aggressive tone that’s slightly louder than Pro Series mufflers and features the same, low interior resonance. Essentially, Flowmaster took their original 40 Series muffler design and made it more “street-able”, by adding “Delta Flow”, noise-cancelling baffles.
Get down-n-dirty with the bass-filled Super 40 Series. This muffler has an all-out aggressive sound that’s reminiscent of a 40 Series Delta Flow muffler, but with a deeper, meaner undertone. Luckily, sound volume and interior resonance remains the same. This makes the Super 40 Series perfect for giving your street machine a muscular attitude without being overly-loud.
This is the standard that all chambered mufflers are compared to. The 40 Series is the original Flowmaster muffler and a benchmark for classic muscle car tone. It sounds as mean as sin, turns heads like a supermodel and numbs your brain with interior resonance. Basically, they embody everything a muscle car should sound like.
Want a sound that says, “Get out of my way”? If so, the Super 44 series is your ticket to the open road. This beastly muffler adds the deepest, richest, Flowmaster tone possible. Simply tap the gas pedal and watch jaws drop. There’s no doubt about it, the beefy tone of this series is sure to draw crowds.
Don’t let their small size fool you, Flowmaster Super 10 mufflers spit & snarl the wildest performance tone imaginable. These puppies are built for power and funnel maximum exhaust flow away from your ride’s raging engine. Super 10 mufflers are perfect for all-out performance and keeping noise-levels legal at the track. But beware—Super 10’s are too noisy for most street applications.
How to Find the Perfect Balance of Sound and Flow
Flowmaster offers mufflers in a wide variety of performance exhaust tones. And, which sound you choose depends on your personal taste and how you drive your car. But, keep in mind that your ride’s exhaust tone varies, depending on the mods bolted to it. Realize that improving exhaust flow & tone also makes your ride louder. So, it’s best to stay conservative when choosing accessories and follow these tips:
- Install a tubing size that your motor needs and nothing bigger.
- Be realistic when choosing a muffler—if you plan on commuting, don’t use a race muffler.
- Don’t over-buy. It’s easy to lose horsepower by bolting an expensive “racing” exhaust on a stock engine. Instead, choose an affordable kit that’s designed for stock applications—the power gains will surprise you.
