        If I start my mod with a Borla s-type axle-back exhaust system, can I complete the upgrade later with the other components of the cat-back exhaust?

        • Unfortunately, the mid pipe, and intermediate pipes included with the Borla Stinger S-Type Cat-Back Exhaust are not available for purchase separately.

        there is a big difference between catback and axelback in sound or power expected with borla S-Type or Attack??

        • Hello! Catback exhausts will almost always be louder and produce more power than their axleback counterparts, which is the case for both the Borla S-Type and Borla ATAK

        I want to get this along with a catted H pipe and long tube headers. Will this make my check engine light come on without a tune and will the catted H pipe by BBK fit unto this without having to remove the resonator?

        • The Borla Stinger S-Type Cat-Back Exhaust will not cause a check engine light or require a tune. High flow cats on a catted H pipe should not set a check engine light or require a tune either, however long tube headers will require a tune for your Mustang to run properly. The resonator can still be used with the BBK Catted H pipe for long tube headers.

            Its Good but...

            Came packaged great and showed up within 2 days so thumbs up American muscle. Took about 2.5 hours to install, amateur home mechanic, I just put the back end up on Race ramps, no jacks, and I was able to reach everything and get it off/install by myself. I unbolted all the hangers, seemed to be a lot easier less fighting with it and made install easier. Now for the product, It has a great Tone to it but judging from the video I thought it would be louder, you can hear it, unlike stock exhaust which you cant, but it wasn't as loud as I was thinking from watching the video, really quiet at idle almost unnoticeable. 2-4k RPM is its sweet spot, I drove it with just the driver window down, again was hoping for a little more, maybe the ATAK would fill in that sound void? I just replaced the stock cat back, I did nothing in front of that so maybe with some changes it can be louder. Its pricey, not sure the level of sound I got was worth the cost, it doesn't sound close to a v8 if that's what your looking for as I was, you can tell its a 6cyl. To be honest it sounds like my girlfriends 350z. I got a cool Borla hat with it too free so there's that.

            Amazing tone from the S types. Exactly what I was looking for with the v6. Paired with the KandN filter this really woke the car up. Not a Loud exhaust but a very fine sound with real performance.

            Worth every penny!

            I got this installed at a local shop for $150. The sound tone is perfect but I’m still considering getting an H-pipe to get the loudness out of this set up. I find myself lately using a lot more gas simply because I love the way it sounds revving up lol.

            Pretty much a must buy

            This exhaust is just awesome. It is the perfect balance of quiet when need be, and wake the neighbors if you want. The idle is still quiet and at slower accelerations while in Drive, but the second you touch that throttle it opens right up into a nice rumble and is pretty loud. I always felt the "sport" mode on my automatic mustang was kinda wonky, but with this exhaust it changes everything. The rumble stays at all times cause the RPMs naturally stay higher, and the down shifting while breaking has a great rumble with crackling to it. It's just impossible not to smile when driving it.

            One of the best sounding out there.

            Soon after I installed the long tubes and h-pipe, I knew I needed these. Although, I needed to get that straight piped sound out of my system. I took off the OEM cat-back and drove around for a bit with my buddy. Man is it loud but rasp is too much. Put it this way, upon startup, all my mirrors were shaking and if I revved above 3k people had to cover their ears. Very tasteless sound and would be a terrible daily. Onto the important stuff. After that little bit of afternoon fun, we got to work. OEM cat back removal: We loosened the clamps holding the resonator to the h-pipe. Then unbolted the 2 hanging mounts in the middle and then slid the OEM cat-back out towards the engine. Borla Stinger S-Type Installation: We had connected the cat-back together before going underneath the car and tightened all the clamps enough to keep it from falling apart but, enough to swivel the parts if need be. Then we slid it under the car, raised it, slid it into the rear hangars, bolted on the mid hangars that we removed earlier, and then clamped the resonator to the h-pipe. NOTE: the resonator that comes with the S-Type is directional. We had installed it the wrong way and the h-pipe didn't line up with the resonator pipes. Once we turned it around, it was okay. Startup was amazing, this is the best my 3.7 will sound. Once it's down to idle you don't really hear it but, putting around at 1-3k rpm sounds deep and throaty. Get on the throttle and it sounds amazing. The resonator really controls the rasp. But man is it loud. OH AND deceleration is my favourite. Since I drive stick, I get a lot of resonated gurgles and the occasional pop. One of the best purchases I've made so far. All in all, about 2 hours. I've put 1000km on it and I'm starting to get engine codes. The computer thinks my catalytic converters are dying but, they're just free flowing. Mind you, I have long tube headers and a catted h-pipe, so this could be part of the reason why. If you're hesitating, don't. It's worth every penny.

            Great exhaust

            At 1st is actually quite deceiving because it’s so quiet inside the cabin but I let my friend drive it so I can hear it from the outside and it’s EXAXTLY what I wanted my mustang to sound like! Not too loud but loud enough to be a very pleasant sound

            Stop thinking about this and buy it!

            You will not regret this system! With the BBK long tubes, BBK H-Pipe, and the Borla Stinger cat back, it sounds amazing. Prior to this I had Flowmaster Outlaws. There is a huge difference. The best way to describe it is the exhaust now goes out of the back instead of the interior. The Borla S is not too loud, no drone through 80 mph any beyond, has a nice racy tone, yet still can be noticed. It’s a bit loud during cold start, however, my neighbors stopped complaining. This is a must for the V6 S550!

            Sounds Great

            I have long tube BBK headers, and H-pipe with this combo these are loud. A stock 2015 GT mustang started to rev his engine next to me at a light, and I could not hear him. Some of the pipes at the ends were dented, and would have been difficult to install myself, luckily I took it to an exhaust shop and for $150 I was able to get them to fix it and install it. They are not raspy, and have nice low growl to them, with a few pops here and there.

            Do yourself a huge favor and install this system MUFFLER FIRST per included Borla instructions. Trust me in that it will go much, much quicker. My install took about one hour after I put my mustang on car jacks since I also wanted to replace all the rotors. The sound from this exhaust is ok but I wish it had a lower growl. Anyway, the quality of this exhaust is great and the service from American Muscle is world class.

            Very fine. Very fine indeed.

            This is my second go round with aftermarket exhaust systems on my car. The first one was the Flowmaster Outlaw axle-back, which I've previously reviewed. I did a lot of research before deciding to replace the Flowmasters with these Borlas, and I can't believe how much better I like the Borlas. These give a nice deep, throaty growl to my car. Unobtrusive, but definitely noticeable. You're never going to get V8 sound from a V6, but in my opinion, this is as good as it gets. Lots of energetic pops and burbles on decel with the manual trans, and acceleration gives you snarls, growls, and good hearty bellows, like Vikings decimating their latest bounty in Valhalla. However, even with the abundance of auditory pleasings when she's going wide open, at highway speeds there is nary a whisper. I dare say they are even quieter than the stock. This is an excellent cruising system that isn't fatiguing in the least on those long road trips. Overall I am very, very pleased with the performance and sound from this package. Highly recommended.

            Turn Heads

            Brief - GET THEM, they are amazing. I have had these on my S550 for 1 year now (40,000 miles, yes I drive alot) and I will say this, if you have the 3.7 V6 you absolutely must get a set of the Borla cat-backs (touring/s-type/atak). They are worth every single dollar. For those on a budget, if I had to choose between getting the s-type or $1300 of other mods I would choose these every time. How it sounds: The completely change the sound and feel of your V6. They sound amazing and high performance, not at all raspy like some old sedan with a rusty muffler. They give a deep throaty roar with just the right amount of bubble and crackle when you shift. When driving around town I noticed that when you take your foot off the gas around 2-3k rpm they make a pleasing and mean gurgling and crackling (manual transmission, don't know if they do this for auto). I've heard all 3 in person and I chose the S-type because I think it has the best note. They are just loud enough to stand out and be heard in traffic but not enrage your neighbors at night. The Touring are a lot softer and the ATAK are more loud and raspy. The finish is great (made it through 1 salty snowy winter just fine) but I felt the fit leaves something to be desired. They are simple to install, but out of the box they fit flush with the rear bumper, which is not really my style. So i spent an afternoon bending the hangers so the tips stick out just far enough that you can read the word "BORLA" on them. On the performance side of things I was completely surprised at the difference they made. These were the first performance affecting part I put on my V6 and I immediately noticed the car pulls harder, even more than that the engine was really responsive, perky, and more fun to drive. The stock exhaust must really choke the engine. Don't be shy because of the price, they are worth every dollar.

            Amazing Exhaust!

            This is a must buy, not only is the power gain noticeable but it makes the exhaust almost sound like the V8. I have people and friends tell me how good the exhaust sounds all the time. The exhaust is loud but it does not drone at all which is very nice. I would definitely recommend buying this exhaust, it has made the car a whole lot more enjoyable to drive (as if it wasn't anyways).

            Disappointed with the sound

            Very easy to install, about 1 hour, had the rear up on ramps. Disappointment occurred during start up. Exhaust tone is much higher than I expected. From the sound clips, i expected a deep throated sound. Instead it almost sounds like a hot rodded honda instead of an American muscle car. I would not buy these again, tempted to put my stock exhaust back on.

            Great exhaust, but a tad pricey

            Sounds amazing on my V6. Took a couple hours to put it on with my Dad's help. It gets loud when you want it to, but stays quiet when you're just cruising. It drones a little bit when going above 70mph on the highway, but you'll forget it's there if you're talking with a passenger or listening to the radio. The pricetag is a bit steep, but you can definitely tell that it's made out of higher quality materials than the stock exhaust. The huge upgrade in sound over stock is worth the money, imo.
