We recently installed MRT's Interceptor Axle Back on our 2015 Mustang EcoBoost and even though it's a four cylinder actually had a really nice, deep tone to it. We know a lot of GT owners are looking for that deep tone as well. We figured if the Interceptor's have it on the four cylinder, it'll probably sound even better on the GT. Today we're going to install MRT's GT Interceptor Axle Back on my 2015 Mustang GT.

The MRT's Interceptor Axle Back is made in the USA using high quality 304 stainless steel and a nice set of four inch polish tips. These will require cutting as all Axle Backs will. MRT includes the necessary hardware for installation. In case you somehow haven't heard one yet, here's some stock 2015 GT exhaust clips. Now let's get started with our MRT's Axle Back. For this installation need a lift or a jack and jack stands, half inch ratchet, 15 milliliter socket, tape measure, marker, sawzall and safety glasses.

The MRT's going to require you to cut in this neighborhood here just like many other Axle Backs you've installed on the 2015 Mustang. The way they do it is follow the curve until it ends. I'm going to measure over two inches from the end of the curve, mark and cut. Once it's cut now slide it off the hanger. Once you have the cut made, make sure it's nice and clean. Put the clamp up into place first. Start by putting it up into the hanger first, get it aligned. Slide it over and I'm going to grab a hammer to push it all the way over and tighten the clamp. Repeat the process on the other side. Now let's see how the MRT Interceptor's sound. Definitely do have a nice, deep tone at idle. They get louder for sure when you rev them up, not raspy at all. Definitely have a nice tone of not overly loud.

The MRT Interceptor definitely has that deep tone at idle. It's kind of reminiscent almost of the MagnaFlow competition where the exhaust almost sound like it has a loak, cause it has such a deep tone at idle. It really sounds good. Lower RPM's or normal driving I'd probably put this in the same category as the MagnaFlow Street System where it's one step up from your stock system. It's not overly loud. I said it has that real nice, deep tone at idle. When you drive it, it sounds very similar in tone to the stock system at lower RPM's but it's a louder version of it. The one place where it really differs is higher RPM. Once you get above say 4000, 4500 RPM the MRT system changes pitch. It gets a lot more of an aggressive sound. It's not raspy at all but it's more aggressive tone, something the stock system never does.

Here we are cruising 2000 RPM in sixth gear. It does have a little bit of a drone to it. It's not one of those that get inside the cabin and gives you a headache but it seems like the exhaust systems that have that deeper tone at idle that people like, the trade-off is going to be a little bit of a drone on the highway as well. The MRT Interceptors were exactly as advertised. They had a really nice deep tone at idle but still got a nice, aggressive sound when you really get on it. Installation, even though it requires cutting, it's pretty straight forward. Take you around an hour, you'll be back on the road in no time.
