California Residents: Proposition 65 Warning
Novice skill is required for this installation.
The KR series axle back from MRT is a T304 stainless steel high quality mandrel bent muffler delete. Features a set of four inch polished tips and like all axle backs, will require a cutting for installation. MRT includes both pipes and necessary clamps for install.
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 axle back.
For this installation, lift or a jack and jack stands, half inch ratchet, 15mm socket, tape measure, marker, sawzall and safety glasses.
The MRT is going to require you to cut in this neighborhood here, just like many other axle backs you've installed in a 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. Start the install, take the supplied clamp, put it over the factory pipe, start my putting the MRT exhaust up into the factory rear hanger. Line it up with the pipe and slide it over. Once the pipes in place, you can tighten down the clamp. Repeat the processing other side and your installation is finished.
Now let's see how our MRT KR axle back sounds... Nice deep tone at auto... Definitely loud and aggressive when you get on it...
The MRT KR series also has a very deep tone at auto. It's honestly not as deep as our receptor series, but it still has that kind of deep tone to it. Again, these are designed pretty much just to be... I mean it's wide open, it's a muffler delete so it's meant to be loud.
I'll be the first to admit, I didn't expect to like this. Usually my experience, as soon as we take the mufflers off, usually I'm getting a pretty bad tone out of it, but in this case, in fact we still have the factory resonator and the factory casts. Doesn't sound bad at all, actually sounds pretty good.
When you get on it, I bet it's loud. I got the window's up obviously which keeps the interior nicely insulated, but it's loud, you can definitely hear it, but it's not painful loud. It's loud kind of in a good way.
The whole tone is just... It's a different tone than a lot of systems we put on the car. A lot of them have a little bit of raspiness to it, but this is just... It's a deep tone to begin with and sounds going to cross the RPM but never gets that raspy tone a lot of the systems do.
When you get on it, you will hear more crackles and pops and when you're talking about a muffler delete, that's just going to happen. That's the sound you're going to get and there's a lot of people who like that. If that's the sound you're going for, this might be the one you want to consider.
All right, here we are cruising 2000 RPM's on the highway, the dreaded drones zone and yes you get a little drone out of these. I'm not going to lie. I've said before, when you get the mufflers with the deeper tone, often times the trade off is a little bit of a drone. In the case of these, yeah you're getting a deeper tone, but you've got no muffler to change your one. When you're cruising, you do get a little drone out of it.
As I said, this system has a nice loud aggressive sound. I can only imagine it with one of our resonator lead H-pipes or X-pipes on here. If you're looking for obnoxious, that might be the way to go.
MRT advertises the KR series as their loudest and most aggressive exhaust system, I'm going to say, it probably is one of the loudest one's we've heard on the 2015 as far as an axle back goes. Remember this still has the factory resonator. If you did the delete, I can only imagine how loud it would get then. Installations pretty straight forward. You do have to cut, the whole install will take you about an hours, be back on the road in no time.
