Whether it's the Mustang GT or the EcoBoost, the number one question I always get asked is, "What exhaust sounds the best?" My answer is always the same. Exhaust is very subjective. What sounds good to you, doesn't necessarily sound good to me. That's why we do as many videos as we do so you can listen to the sound clips for yourself and make an educated decision. The one thing I can guarantee you is that EcoBoost is never going to sound like the GT. You have to have that V8 growl, I suggest getting a V8. Doesn't mean though, the EcoBoost can't sound better. MRT has been involved in the EcoBoost since the beginning, really should do their Turbo-Back system, they have several Axle Backs as well, including the Interceptor. Today we're going to show you how to install this and give you some sound clips.

The Interceptor series designed to give you a nice, deep tone. These 304 stainless steel mufflers feature mandrel bends, are made right here in the USA, are also far lighter than the factory mufflers. They end is a set of polished four inch tips, and like all axle back systems, will require cutting for installation.

First installation, need a lift or a jack and jack stands, half inch ratchet, 15 millimeter socket, tape measure, marker, sawzall, and safety glasses.

We're going to be installing the MRT Interceptor on our EcoBoost fastback, but it'll also fit your convertible. Like I said, it's an axle back, it will require cutting. Regular viewers are going to know we've cut the exhaust system off this car a long time ago, but the basics of what you're going to do is follow the curve of the muffler, when the muffler curves into a flat section, measure over two inches, cut it straight off.

The pipe almost has a mark where you want to cut. Follow the edge of the curve where it's flat ... Make a little mark and that's where we're going to cut.

We're going to make sure once you cut it, just go back through, just de-burr it real quick and make sure there's no sharp edges.

Beginning installation, take the MRT provided clamp, just put it over the stock pipe, now we'll put the muffler up into place.

What you do here is get it started in the rear hanger ... You want to basically push it into the hanger till it lines up with the pipe and slide it over.

Pull the clamp over into place and tighten it down.

You want to repeat the process on the other side and installation is finished.

All right now let's start it up with our MRT Interceptors. Soon as you fire it up, it does have a nice, deep tone at idle. I got to say, this is definitely one of the deeper tones I have heard on EcoBoost. Now let's take it out and do some driving.

The first thing you'll notice about the MRT Interceptor is they've got a nice, deep tone at idle, but they're not particularly loud. You're looking at a little bit of sound to your EcoBoost Mustang, but don't want that loud, regressive, four-cylinder tone, these are a really good choice. The factory exhaust in this car, you pretty much can't hear at all. Well these ... I would say this would be the perfect, maybe first step. It's definitely louder than stock, you can have a cue that it has an exhaust, it has a nice tone to it, but it's not intrusive at all, I mean really ... If this could be a factory exhaust system, it'd be perfectly acceptable as far as the volume goes.

Again, highway speeds, 2,000 RPM, nothing back there. Sounds like a stock exhaust. No drone. No unnecessary sound. Perfectly acceptable for driving all day long on the highway. You could have a conversation inside of the car, got no problems at all, no louder than stock.

Right there is 2,000 RPM. That's where you're going to get your most likely drone ... Nothing. Zero. I mean I said, not only does it doesn't drone ... Doesn't really make any sound. It's perfectly quiet.

Wide open throttle ... It's got a nice sound to it. It's not, again ... It's mellow. If you're looking for a system when you install it, you go, "Wow this things real loud and aggressive." This is not the one for you. MRT has plenty of other choices including their Turbo-Back or their KR that will do just that. This has got a nice ... Like I said, just a nice mellow, cruising tone to it.

You looking for a nice, deeper tone at lower RPMs and more of an aggressive sound at higher RPMs, the MRT Interceptor is going to be an excellent choice. The installation is pretty straight forward. It will require cutting, but even with the cutting the whole process should only take you around an hour start to finish. Should be back on the road in no time.
