Flowmaster 40 Series Delta Flow Mufflers Review - SEMA 2013

Video Transcription

Hi, I’m Mark with Flowmaster at SEMA 2013 and I’m here to talk to you about some of the different mufflers that we have and how they function and what makes them so unique. This is a cutaway of one of our 40 Series mufflers. This particular model is our 40 Delta Flow. These are our aggressive mufflers, a lot of times referred to as two chamber. The way these mufflers function is the exhaust pulse will enter and we center it over the deflectors, this is what we call a power chamber in here. As the exhaust pulse gets split around the deflectors, it comes back around, sound frequencies are directed into themselves and cancel themselves out. That’s how we can control sound without using any sort of packing material. These mufflers do not degrade over time so the sound you have the first day is the same sound that you’re going to have 20 years from now. That physical reaction of the sound cancellation behind the deflectors creates a low pressure area that helps pull the next pulse through the system faster. That’s where you get the increased pulse velocity, better performance, better throttle response, increased mileage, things like that. Based on the size and the spacing of these deflectors, we can control what frequencies we’re canceling out with sound. That’s why with the different mufflers that we have to offer we can have different not only sound levels, we have different tones. Some are bass-ier or deeper toned than others. You can really customize the vehicle to the sound that you want. We’ve got 15 different mufflers to choose from just for the street vehicles and you can get them all at
