    Review & Install Video

    What's up, guys? Stephanie with AmericanMuscle.com and this is my review of the Magnaflow Street Catback exhaust fitting 2015 and up EcoBoost Mustangs. The Magnaflow Street Catback is going to be great for the S550 EcoBoost owners out there that are looking for more of a toned down or quieter system that isn't over the top or too loud, but one that has a deep sound and a good quality. This is a perfect option for the guys that are not looking for anything too loud, and just want something mild that's going to open up some exhaust flow and give a better sound than the factory exhaust. Like most setups, this catback is going to eliminate the factory resonator and replace it with just a Y-pipe. And not only is this going to open up sound and exhaust flow and ultimately power, but it's also going to bring up some weight too. Magnaflow then gives the system their Street series mufflers, which is a straight through design, but I will say right now that even though they are a straight through design this is not a very loud catback as you guys already heard from the sound clips. This is a two and a half inch catback that is a full stainless steel catback and it's also mandrel-bent. You're looking at four and a half inch polished stainless tips out back, which is awesome in my opinion. Stainless steel's always a great option for the cars that see all different types of road conditions, because it offers great corrosion resistance. And it's nice to see that Magnaflow has stepped up to that two and a half inch system instead of sticking with a two and a quarter inch exhaust, especially considering this is a turbo car and opening up that exhaust is always going to benefit you. I know you can hear that this catback is deeper than the factory exhaust, but it's not very loud. You hear more of the deepness in tone here. And as RPMs climb, this catback stays deep, but it doesn't really increase in volume at all, which is what makes it perfect for those that are looking for a tamer exhaust. I'd even go as far as saying that this catback does maintain some of that stock sound in the higher RPMs, and you can hear it in the sound clips since there isn't a ton of volume here. This catback gives a smooth sound, which makes it sound more like a muscle car than some of the other catbacks that I've heard. Also, I wouldn't say that there's any sound distortion here either because you don't have the volume for that. Maybe more towards red line there's some, but that's normal, even with the factory exhaust. There also isn't any popping or anything on decel. The sound stays smoother as well. And speaking of that, there's no rasp to the system. Some people love a raspy note, and others try to avoid it. So if you're looking for loud or raspiness, then there's some other better options for you on this site. Another plus of having a quieter system like this means there's no interior drone. You almost don't even notice that there's an aftermarket exhaust in the car at cruising speeds, so that means you won't have any trouble having a conversation or listening to the radio on the highway. And so you won't have to worry about dealing with drone on trips. So like most aftermarket catbacks, this one's going to open up some of that nice turbo noise. You can hear the turbo spool and you get some of that blow off noise as well. Now, with all of this being said, you have to keep in mind that this is a four cylinder turbo car. It's not going to sound like a V8. But this catback does have that clean deep type of sound that's relatable to the sound of a V8, so if that's what you're looking for then you're looking in the right place. Overall, this is a deep sounding system that's not over the top at all and is actually quiet when compared to some of the other options that are out there for the EcoBoost, and it's actually one of the quietest systems currently available. So I'm going to give it a two or two and a half out of five on the loudness scale. With catbacks, it really all depends on what you're looking for and luckily there are quite a few options out there. When we start to look at price, we see that this Magnaflow catback is going to be towards the top of the line, costing over $1,000. This is a full stainless steel option so it's not unusual to see these costing more, and this is not the most expensive option that's out there. You're looking at about $1,100, but this is one of the higher quality systems and it also steps up to that two and a half inch diameter. When it comes to the install, you're going to be looking at an easy one out of three wrenches on the scale when we look at difficulty. This is a direct bolt on item, so you won't need to cut anything or modify anything to get it installed. All that you're really going to need is a socket set, and a lift would certainly make things easier, but the job can be done on stands as well. Going to be removing the exhaust from the resonator back, and an extra set of hands can make things easier for you here. You'll be moving the rear hangers to the new catback, so I'd recommend taking them off of the factory exhaust when you drop that. It'll make the swap a little bit easier. The only other thing you'll reuse is the front clamp off of the resonator for the front of the new catback. The whole catback can be dropped as one big piece, which is why an extra set of hands can really help here. When you go to install your new setup, it'll probably be easiest to start from the front and move back. So install the Y and mid-pipe area first, then the intermediate pipes and the muffler assemblies. I'd leave everything loose until you have it all lined up and then tighten it down. The catback does come with four new clamps, so you don't have to worry about picking those up. You can figure on spending an hour or two from start to finish to get all of this done. Overall, the Magnaflow Catback is a great option for those looking for a quieter, but deep sounding system that's not going to be too loud. It's a two and a half inch system that utilizes a Y-pipe, the two Magnaflow Street series mufflers, and it's a direct bolt-on item that requires no cutting. You can check this catback out online some more for yourself and for all things Mustang, keep it right here at AmericanMuscle.com.

            Best sounding exhaust for the EcoBoost.

            I love the sound of this exhaust. It was exactly what I was looking for. The build quality is good and looks great on the car. Just make sure who ever installs it tightens everything properly. I had a shop do it for me and when I got home I could smell plastic burning... The Exhaust tip shifted on one side and was resting on the plastic bumper cutout. Thankfully I discovered this right away and fixed it myself. Luckily I had a floor jack and stands. Other note is that the exhaust tips don't stick out very far past the plastic bumper, so all the heat goes straight up and could cause you reflectors directly above the tips to warp. I had to remove mine. Other than that, very happy with my purchase.

            Good Exhaust for the EcoBoost

            This is probably one of the best exhausts for the EcoBoost if you don't want that "ricey" sound from the four cylinder. I'm very impressed with how deep the tone is from this exhaust. Volume-wise though it's not much, if any, louder than the factory exhaust. Only gave it four stars on fit and finish as the driver's side fitment was rather close to the sway bar, no matter what adjustments I made. Wish Magnaflow would package a little better too, as UPS Freight was not kind during shipment and one of end tubes ended up getting bent (not the driver's side where there was a fitment issue). Overall still very pleased and most of all, the wife likes the way her car sounds!

            Convertible issues

            Looks great,sounds great. However, regardless of what is written by Magnaflow or other reviewers, first installer couldn't do the job, and second installer who has done exhaust for over 30 years had to make modifications to the braces under the car. These are braces that are only on the convertible model. Unfortunately, time is money,and it cost me 2 1/2 times what it should have.

            Quality upgrade over stock system

            I was very hesitant before purchasing an exhaust system for my 2018 Mustang Ecoboost. I looked at all options but wanted something on the quiet end due to the quite awful sounding systems out there. This isn't a boxer engine or a v8 and honestly I think a lot of the systems sound like trash. The Magnaflow Street cat-back is not one of them, though. Fit and install was about 1 hour on jack stands during my lunch break while working from home. Definitely helps to have another set of hands for removing the existing exhaust and lining up the new one. Also, don't worry about the smoke. My exhaust shipped with what I assume is a cosmoline alternative or something covering it. This WILL cause white smoke when your car is running while the coating burns off. For me, driving in sport mode for 5-10 miles per day, I was able to get rid of smoke after about 4 days. You may still notice a smell after as well. The look is great and fills out the space nicely.

            Not Bad!

            My car is a convertible so it fit very snug to the point of vibration. I made adjustment to passenger side brocket and started to brake the weld. Not cool. So now I have to welded. Could have been better experienced.

            Absolutely Perfect Sound

            After doing quite a bit of research into a "mild" Cat-Back that could transform the Ecoboost sound from non-existent into an actual muscle car, I settled on this MF and I could not be happier. Perfect deep resonance and after breaking in the sound is the way the stock car should have sounded. One point of note that I had to fix after the fact is that the exhaust hangs low enough on the convertible to contact the sub-frame support which was causing me some annoying vibration noises anytime there was uneven pavement. This was fixed by purchasing some heat resistant padded self adhesive "tape" which I used to make a pad and slid between the points of contact. All vibration noise is gone and I couldn't be happier with this system.

            EcoBoost headache maker

            Deep sound, but still not what I was hoping for. It vibrates at certain RPM's and the drone gives me an actual headache. Wish I could turn off the ANC in the mustang to see if that is the issue ( it was in my Infiniti ) I have the convertible and had a Ford dealer install it, I also have the Ford performance tune \ air cleaner. Other than that it is stock.

            What a nice deep tone. It's exactly what my pony needed. People are right...sound clips on the internet do this system no justice. No rasp...no fartcan sound. This is the system that should have been in the eco mustang from the start. It's a perfect match to the 2.3l engine. Had a shop install it. Took about 90 minutes. No problems. Gives the car a nice deep classic sound. Not loud...but very cool. Love it.

            5 Stars but I kinda wish.....

            So the Magnaflow is a great exhaust but after having it on for about 6 months, I kinda which I had the competition. I didn't wanna sound too RICER and loved the reviews of how deep tone and subtle it is. But honestly, its a little too subtle. Kinda wish it was a bit louder. I didn't want to the drone which this doesn't have but just about every car I come across sounds better than my car. If you haven't purchased it it, go with the competition instead of the street. I'm pretty sure I'll upgrade my exhaust yet again.
