An MBRP performance exhaust system is the starting point to getting the most from your cold air intakes, tuners and other bolt-ons. Paired with a set of longtube headers, this system will not only sound amazing, but also show immense power gains. Aiding in those power gains is a high-flow H-Pipe and large 3” mandrel-bent stainless steel piping all topped off with flashy 4-1/2” polished tips.
Installation is a breeze with a lift and not too bad with a jack, considering it’s a 100% bolt-on installation with basic hand tools. MBRP designed this exhaust system with longevity in mind considering it features rugged 16-gauge T409 stainless steel construction that will withstand whatever the road throws at it. Right out of the box, this cat-back system is polished to give off a show quality mirror finish to match the tame, yet pronounced exhaust tone.
The 5.0L Coyote engine from Ford has been around for a few years and makes a huge amount of power, but the exhaust note just isn’t there to back up the powerhouse that lies under your hood. This cat-back system from MBRP will take your S550 to the next level without making your ears ring. The exhaust notes of this particular system are subtle and civilized during normal driving, but quite aggressive when your gas pedal hits the floor.

What's decibel is this exhaust? WOT (wide open throttle) and idle? In your opinion Is this one of the loudest systems for the 2015 GT?
Hi, do you ship to mexico?
How much would it be to send a cat back exhaust to 2671. , Nsw , Australia
Are you able to ship an MBRP Cat back Street in stainless steel for the Mustang 2016 5.0 GT to the UK? If so can you give a total price? Many thanks
Read that the refector above the tip melting but also read that the tips are double walled. If they are it seems unlikely for this to happen. Any info on this?
Do you you know what the max noise level would be for the street series exhaust is please?. In New Zealand the max we can get away with is 90dBA, and from what I can see California is the strictest state in the US, and its max level is 95 if I'm not wrong
Same sound from the Stainless Steel vs the Aluminized? I am looking for a no drone application.

It starts by replacing the resonator with a true H-pipe to give you that muscle car sound and goes through true 3 inch mandrel-bent pipes, through a set of their street mufflers and even a set of 4 and 1/2 inch polished tips.
We're going to start with some sound clips of the factory exhaust. First a few in our studio and then we'll take it for a ride.
For this installation your going to need a lift or a jack and jack stands, 3/8" ratchet, 13mm shallow socket, 15mm socket, 8mm Alan key, 6" extension and a flat blade screwdriver.
Like we've shown you many times in the past, removing the stock exhaust system is actually quite easy but we do suggest a second set of hands to make it easier.
The first thing you want to do, remove the two bolts for the two rear brackets. Don't worry about removing the bolts. There's actually a little hook so they're not going to fall off.
Now we move forward and loosen the clamps that hold the resonator to the front parts.
And we want to move this little tab up. Little stud that will stop it and then you can slide the clamp down.
Now you can pop these little hangers off here.
Okay, now the weights going to go forward and you sort of shimmy the system forward off the rear clamps.
We're going to remove these clamps off the factory pipes. Move them over to our MBRP.
First we're going to install the factory clamps back on the factory pipes. I'll grab our new H-pipe.
Install the H-pipe with these flat sections with the circles facing downward.
Now we'll just snug them up a little bit.
To install the MBRP, we also have to remove the rear hanger bracket to the tail pipe. There's one bolt here and one up on the side.
To prepare the new pipe for installation we're going to install all the factory hangers as well as the new clamp.
Alright, now we're going to tighten the front clamp to the H-pipe.
Now you can put the tip up into place and you can kind of put it wherever you want, as far as you want. Usually try to line it up right with the edge here. And repeat the process on the other side.
Has a very aggressive tone as well. Very similar to the Race, just a little bit less volume overall, but still that nice deep tone and idle and an aggressive sound when you hit it.
Considering how loud it is outside the car, it's actually surprisingly quiet inside the car. There you go, there's 60 miles per hour, 2 grand. I would say a hint of a drone at most. This wouldn't bother me at all for daily driving, for long highway commutes, whatsoever. You can really barely hear it. Even with acceleration, you can hear the aftermarket exhaust, it's not overbearing at all. Definitely considering how loud it is outside the car.
Has a nice deep tone at idle, too. Just sitting at a traffic light you can definitely hear it's an aftermarket exhaust but it's got a nice tone to it. I mean it's a really muscle car sound, a really deep muscle car tone.
If you like the sound of the Race system and want something a little more mellow, the street is going to be the perfect choice. You still get that nice deep tone from the H-pipe. The Street muffler just keeps the volume a little bit lower. Inside the cabin it's nice and quiet but still has a nice aggressive sound outside. As far as bang for the buck, MBRP's going to be tough to beat.
