Justin: Hey, everybody. I'm Justin with AmericanMuscle.com. And I'm going to be breaking down a very budget-friendly catback system for your S550. I'm taking a closer look at the MBRP street catback exhaust system, fitting all 2015 GT's. MBRP is a Canadian-based performance exhaust company that's been making exhaust systems for a wide variety of applications for nearly two decades. Now their systems are definitely known to be on the more aggressive side, and as you guys heard, even though this is their street system, it still offers plenty of bark for that low muscle car rumble, thanks to the included H-pipe. A big thing I do want to point out here, though, with the MBRP systems is the price. Now as I mentioned at the beginning of this video, these things really do offer a great bang for your buck, and they come in at nearly half of the price of some other catback systems available for your 2015 GT. Another thing to point out here, when choosing a street system for your S550, you do have a few options here at American Muscle, including a full blacked-out version like you see here. They also offer a fully polished version of the stainless steel polished mufflers and polished tips. And if you're really looking to save a few bucks, well then they do offer a aluminized steel tubing version, which is basically the same exhaust I have with me here, but utilizes aluminized steel tubing in place of the stainless steel tubing, if you're looking to keep things on a very tight budget.All right. With that all out of the way, guys. Lets get into some of the details here with the MBRP street system. You are going to be looking at 3" mandrel-bent stainless steel tubing again with this kit here, leading into the street series mufflers and then out the 4 1/2" slash cut tips, etched with that MBRP logo. Now since this kit does utilize a true H-pipe design here, you are going to get that low, thumping muscle car tone that's typical when using an H-pipe, as opposed to that raspiness that comes along with an X-pipe. You'll be happy to know that catback installs with a 2015 Mustang are definitely much easier, compared to older generations, thanks largely in part to that new independent rear suspension, meaning there's no over axle pipes or anything like that. And because the MBRP is a direct bolt-on modification, meaning you don't have to cut whatsoever, you should be able to get this thing knocked out in under two hours, especially if you're working with a buddy.So if you guys are looking to crank up the volume on that new GT, but you want to leave some money left over for a few other mods, then be sure to check out the full MBRP lineup here at AmericanMuscle.com.

Great Sound, Great Price!
As I said, Great sound! Loving the deep sound my car has. Easy to install and though the price seems low, the sound is worth it! It’s loud, not super loud but loud enough to hear you come in and out of the neighborhood. So far I got no complaints from the neighborhood. There’s no drone by the way. Just a deep sound.Helpful (0)

So the install for me was about an hour and man, this was worth ever penny. also, if you put down both back seats, put the passenger seat all the way up, open the passenger door all the way, and then put the window down, you can def put the box in the carHelpful (0)

Iam always looking for the perfect sound...found it!...I had borla racing...very raspy. I had it paired with kooks green catted headers. To me, it was raspy and tinny sound, hard to explain. Did not care for it, so I figured go with the street since I had headers, didn't want it crazy loud with the race. Man, the combination of the headers and the street is absolutely amazing...much deeper, with a deeper rasp on WOT...In my opinion, the best combination I have ever heard. AMAZING and the price...as amazing! The quest for the perfect exhaust note is now DONE!Helpful (5)

Amazing tone and value.
Just received this MBRP Street stainless system. It came in only 3 days and was in perfect condition. I couldn’t wait to get it installed and since I only have a single car garage at my condo I took it to a local shop and had it installed in under an hour. It sounds amazing. Nice and throaty at idle but when you step on it it really wakes up. For the price I just don’t see how you can do any better than this system. Oh and no drone.Helpful (2)

Major upgrade over factory cat back
I just installed this last week and was immediately impressed with both the look and tone. I initially hesitated on the black but now think the black exhaust is the way to go. Great aggressive look. Lastly, the value is unparalleled!Helpful (0)

Just as advertised
Product came in quick and took about an 1 1/2 hours to install. Love the quietness inside the car and the loudness outside the car. That was the main reason I went with this cat back systemHelpful (0)

Convertible Install is More Involved
The street version is pretty loud. Not crazy loud but a bit raspier and louder than anticipated. It is very high quality and install on jack stands by one person is very doable. I have a 2017 convertible and it required removal of the under car bracing which wil roughly double your install time. Took me 3 hours but I went slow. The convertible version is two pieces on each side after the h-pipe rather than a single piece as on the fastback application. That adds some complexity to get it all lined up right. With a multi piece set up that relies on clamps, it tends to sag a bit and there doesn’t seem to be a remedy for that. One side is touching the under bracing which had me worried about possible rattles. Fortunately there is no rattle and all is good, so far. Definitely worth the money and your s550 will sound much more aggressive. My wife hates it but if you’re going to pay up for a V-8 might as well get that muscle car sound you wanted in the first place. The only reason I didn’t give it five stars is the slightly limp set up with multiple clamped joints on the convertible version.Helpful (3)
To those who already own this exhaust system, how is the drone on this? I used to have a 2016 v6 with outlaw axle backs and the drone was terrible, I hated it so much, is this bearable with this one?
The MBRP Black Series Cat-Back Exhaust has little to no drone at any speed. MBRP builds mufflers specific for the vehicle, and drone is one of the many attributes they account for, with having no drone being their ideal goal.
I have the base gt. I see in some pictures some have the base without much less prominent valence (like me) and others have the premium or pp version with a full rear valence. The fitment in the pics is really variable. Some with the larger valence protrude much more. Is this adjustable and to what degree ? What’s the min and max inches length it will protrude from a base Gt? I know it won’t be flush. I want to make sure what I see in pics was adjusted vs luck of the draw with pipe length.
The MBRP Black Series Cat-Back Exhaust has a slight adjustment to it based on how far the slip fit connectors are pushed together prior to clamping. We do not have a measurement on this, but typically ~1" from full forward to full backward can be achieved with this style exhaust.
Could anyone tell me about the boxes that the exhaust came in? I'm trying to figure out if I can fit them in my mustang with the back seats down, or if I'm going to need someone to haul them for me when I take it to get it installed. Any help is appreciated!!
It is not going to arrive pre-put-together inside the box, so you shouldn't have a problem fitting this inside of your Mustang.
Has anybody experienced rattling where the H-Pipe connects to the factory exhaust pipes/Catalytic converter ? I have tightened and adjusted the exhaust several times now, and about every month, the rattle reappears and I need to readjust the pipe in the factory clamps. The H-Pipe has cone-shaped ends and they seem to "slip" out of the of the clamp and cause a rattle at the connection point, the noise almost always seems to come from the passenger side (the side with the flex coupling in the exhaust) once the connection is loose, the flex coupling/clamp/pipe rattle until readjusted.
The MBRP Black Series Cat-Back Exhaust should not produce a rattling. With the pipes loosing connection, this is most likely a case of under or over tightening of the clamp, as too little tension can cause not enough pressure to be applied, allowing this to slowly slip loose, and over tightening can also cause the pipes to be slightly deformed when under load, allowing them to be essentially squeezed out of one another. We would recommend installing the exhaust with a small dab of blue Lok Tite on the threads of the clamps to prevent loosening, and torquing the clamps to the OEM spec of 35 Lb-ft.
Since this is a direct bolt-on for the factor set-up, how does this work with MBRP 3" long tube headers? The headers say they're designed to go with an MBRP cat-back, but they have a 3" connection where it looks like these are smaller to accommodate the factory headers. I could not seem to find an MBRP product that would bolt up to their 3" long tube headers. Thanks!
There would be a step down used to allow them to fit together and bolt up correctly. In the case of an S550 you have adapter tubes that come off of the headers that will accommodate the size needed to bolt these up.
The MBRP Installer Series Cat-Back Exhaust w/ H-Pipe will be aluminized tubing which will eventually rust over time. Whereas the XP series will use stainless steel tubing which will not rust.
There should not be any issues with rubbing with this exhaust kit. We also do not have the measurements available for exactly how low it will sit.
The Stainless Works 3 in Retro Chambered Cat-Back Exhaust w/ H-Pipe - Fastback (15-17 GT), item # 384842, (http://www.americanmuscle.com/stainlessworks-catback-sm-2015gt.html) weighs approximately 64 pounds. The MBRP Street Cat-Back Exhaust w/ H-Pipe - Stainless Steel weighs approximately 61 pounds. Both are significantly lighter than the stock exhaust system. Both of these Cat-Backs will give you a great power gain when installed with other accommodating parts and a custom tune.
The MBRP Street Cat-Back Exhaust w/ H-Pipe - Black Tips (15-17 GT) does jut out a little past the rear valance. The exhaust can be maneuvered and moved around to adjust where the tips will sit but they will not sit flush.
These have not been submitted for Carb Certification at this time, so no, they will not be carb legal.
This includes a straight through muffler, which the most aggressive exhausts feature either a straight through muffler, or a muffler delete. Now, compared to the other straight through mufflers, this is going to be on the quieter end. However ultimately we would be comparing really loud, to really really loud, meaning this exhaust will still be one of the more loud and aggressive mufflers we have to offer, and therefor more susceptible to droning.
It could be an issue with the catalytic converters. We recommend having an exhaust shop take a look to confirm.
This MBRP Black Tipped Street Cat-Back Exhaust Kit is specifically designed to fit all 2015-2017 GT Mustangs equipped with the 5.0L 4V coyote engine. This will not fit a 2012 Mustang without heavy modification, and at that point, we would not be able to guarantee that this would still work as designed.
