Product Details

FlowFX™ 409 SS Cat-Back Exhaust System with Split Side Exit by Flowmaster®. Exhaust System Type: Cat-Back. Exhaust Tubing Material: 409 SS. Main Tubing Diameter: 2.5". Exhaust System Sound: Aggressive / Loud. Introducing Flowmaster's new line of FlowFX exhaust systems.

Installation

Flowmaster® - FlowFX™ 409 SS Cat-Back Exhaust System Installation Instructions

New features include, bright 409S stainless steel tubing, a pair of Flowmaster's new FlowFX straight-through mufflers with a large core for maximum performance and a deep, aggressive sound. The system uses a Scavenger X-Pipe cross-over and mandrel-bent tubing for maximum performance and then is finished off with stainless steel tips that exit within the rear bumper valance. Manufactured in the USA and is covered by Flowmaster's Lifetime Limited Warranty. Designed for an easy installation, this system includes all necessary parts, hardware and detailed instructions.

All Flowmaster exhaust systems give the same improvement of performance. All Flowmaster exhaust systems produce a beautiful deep performance tone. Choosing between the five different exhaust systems is not a technical decision – it is all up to your personal taste. It’s A Sound Decision™. The racing origin is evident in every Flowmaster exhaust system. All the five series of systems are tuned for maximum performance. They differ in technology and tuning, and thus in tone and character, giving you a performance engine sound to your personal liking.

Flowmaster exhaust systems employ two unique technologies, the patented Delta Flow and the Laminar Flow. They give different characters of sound and can be tuned to achieve the desired exhaust note. Flowmaster Exhaust System Technology is so versatile and gives such a high degree of control that it is used both by racers, who want maximum power, and by the U.S. Air Force in Stealth applications, where maximum silence and minimum heat emissions are prime considerations.

Be it for a domestic or import truck, SUV, off-road warrior, daily driver, muscle car, euro-spec cruiser or sport compact vehicle, Flowmaster technicians personally hand select the right muffler, tubing size, resonator, and tip to make the process easy for you. Best of all, Flowmaster stainless steel exhaust systems are covered by a Limited Lifetime Warranty; ensuring that your exhaust will last as long as you own your vehicle. If you choose aluminized steel products, Flowmaster backs them up with a 3-year warranty.

Sounds Great

Install was not too bad. If you're not saving your factory setup then take a Sawzall to it for removal, makes it much easier. Gives the 5.0 a great rumble but not obnoxious. Sounds awesome on acceleration but fairly quiet at idle.

Perfect Exhaust for my 2024 Ford Bronco Sport!

Love the deep sound from the exhaust now! Tons better than stock, better gas mileage, and better acceleration too. Had it professionally installed, and it was done in about 20 minutes! Definitely recommend Flowmaster Products for ease of installation and high quality!

Flowfx Exhaust

It’s a great exhaust for the price. Install was as easy as can be. It is a bit louder than most aftermarket exhausts but won’t wake the neighbors up in the morning. The only thing that I found that it lacks in is the tip will start to fade and the powder coat will start to flake and the tip turns into chrome instead of black. Other than that it is a great exhaust for the price.

Good Bolt On Kit

This is a good bolt on kit. Just installed on my 5.7 ram yesterday. Seems to be good quality. But whoever rates the sound level gave it loud aggressive. I would rate it moderate/medium. I deffintly like the black tips, better than the chrome!

Great Exhaust

Got it put on with some minor tweaks. Sounds great it gives it a throaty sound but if you are not standing on gas it produces very little drone.so highway driving is not effecting your ears. I felt the pick up in power. Love it!

Great Kit

Great kit, sounds great, easy installation. Only con is factory rubber exhaust hangers are too big for new exhaust. Had to replace rubber hangers with smaller size.

Beware

I just installed this on my 2015 Silverado 1500 5.3L. V8 It sounds good and seems well made, HOWEVER, when my truck drops to V4 it sounds absolutely terrible. That can be fixed with a tuner but it's another $400 I have to spend in order to correct the issue.
