    Flowmaster FlowFX 409S Mufflers

    When you’re in the market for a straight through style muffler with that moderate to aggressive tone that is still street legal, you need to check out Flowmaster’s FlowFX line. These mufflers are universal fit and provide great performance tone with a chambered option that will keep the po po’s away--at least we hope, though in your neck of the woods, we haven’t officially tested this theory.

    On Flowmaster’s grand scale of sound, they offer mufflers that are everything from the hyper aggressive, super loud, practically open header options like the Super 10 to the closer to factory, quiet style, OEM like 50 Series Big block muffler. And one of their top sellers is right in the middle of this cross section of aftermarket muffler goodness: the FlowFX series.

    FlowFX Mufflers

    What makes the FlowFX a stand out in Flowmaster’s great line of mufflers is that it has just enough of a deep mellow tone to give you that aftermarket feel without crossing that line into blowing the eardrums off kids riding bicycles three streets over, if you catch my drift.

    They give you that straight through sound via an exceptional design that uses a perforated steel core inside the chamber which is packed with a plethora of high temperature sound absorption material. This combo of performance tone meets street decibel level driving is what catches the eye--and ear--of most aftermarket enthusiasts.

    It really falls into that sweet spot where you get exactly what you want without too much over the top rumble that will have the neighbors calling the police every time you fire up your pickup truck. Sound violations--we’ve all had them. But this muffler gives you that tonal appeal without the decibels that the boys in blue love writing tickets for.

    FlowFX is made of super high quality 409 stainless steel. This muffler is designed to last. Using top of the line mig welding, the FlowFX is a grade above the rest of the market. And perhaps what’s most impressive is the great price that these mufflers come in at. Don’t take that as a cheap muffler either. These babies are performance, through and through. They just won’t break the bank with their price tag either.

    And since they are universal, there’s likely an option for your vehicle. If you’ve got 2 and a half inch (2.5 inch) pipes, Flowmaster has you covered. More like 3 inch? Yup, we’ve got you. Need a 2.25 inch or 2 and a quarter? Done and done.

    And the best part is FlowFX has options that are truly straight through as well as the chambered straight through style, so you can get the muffler you want and make it fit where you need to too.

    If you’re dealing with limited space under your vehicle, consider the round body, very straight through mufflers. If you have more room to work with or want that dual exhaust style, they offer a dual out option as well. So pretty much whatever you’re looking for, chances are good that Flowmaster’s FlowFX can give you what you want.

    If you’re looking for a full exhaust system, Flowmaster offers those as well, including a cat-back option with a FlowFX muffler. You can check that out over on our Exhaust System page too if you’d like to give the whole kit and kaboodle at once. We actually recommend going with a cat-back system if you want a real overhaul of  your exhaust. But if you just want the muffler, this is the page for you, and FlowFX is the muffler for you too.

    Don’t forget to make sure you get some sweet exhaust tips too though for that muffler. We’d call that an Axle-back exhaust system, but you can just call it a muffler with exhaust tips. We won’t judge.

    How do I get my Truck to Sound more Aggressive?

    That’s a question we field all the time. I fear that a lot of us when we think about rugged or aggressive sound think back to those old school glass packs. You know the ones I’m talking about, right? Those red tubes that make your exhaust sound… well… kinda awful, if I’m being blunt and honest here.

    I think there is a misconception that the only way to get the sound we want out of our trucks these days is to use straight pipes or go no muffler or old school glass packs. And the truth is there are other ways to get that sound without risking a ticket from your local police every time you take your truck out on the town.

    I come from a small town where the cops don’t have much going on. And growing up, I can’t tell you how often myself and my friends got tickets for sound violations and the like. Don’t get me wrong, back then I thought fully open exhausts and super loud bass subs were where it was at. These days I know a bit more and have seen a whole lot more of it to boot.

    And the truth is, you don’t have to lose your muffler to get the sound most of us are after. That’s where Flowmaster and FlowFX comes in.

    You can get the FlowFX in a chambered body that looks like a traditional muffler and will keep the decibels at an appropriate level while giving you the tone or sound your after.

    These mufflers are designed by enthusiasts to give you the muffler sound you want. And whether you want the round style or the chambered look, these 409 stainless steel cases are built to take a beating and then some.

    And the sound quality is going to be there. You don’t need to lose your muffler or your cat. You don’t have to go straight pipe to get the tone you’re after. We aren’t in high school anymore. Muffler technology has improved over the years. And now it is finally possible to get that moderate to aggressive tone without opening up your exhaust so much that you lose out on all the scavenging that your engine needs to perform at optimal levels.

    I think we sometimes forget about that part. While stock exhausts are almost always too small, you don’t want to over compensate either. Flowmaster knows all of this. So they are going to make sure you get the size pipe and exhaust you need to make your engine function at optimal levels. And if you’re looking to learn more about that, check out our Exhaust articles in the Aftermarket Academy or explore the Exhaust and Exhaust Systems pages here too. We want you to get the exhaust your truck needs with the tone that you crave. And we think FlowFX is a great option for you to consider to make your truck growl the way you want it too, while still maintaining great performance specs.

    And should you have any exhaust related questions, please don’t hesitate to contact us via chat, phone, or email. We have parts experts standing by to field your questions. Exhausts can seem over complicated at times. There’s nothing wrong with double checking fitment with a parts expert on our team.
