    Review & Install Video

    Hey, guys, Stephanie with americanmuscle.com, here with an overview and install of the Pypes Street Pro Touring Axle-Back Exhaust, fitting 2015 and up, GT Mustangs. We're gonna be talking about a few different things with those exhausts today, but mainly we'll talk about the sound of the axle-back and the install. The install for this is easy. It's a two out of three wrenches in the difficulty meter since there is some cutting involved. But I'll get more into that later. The Pypes Street Pro Touring Axle-Back is going to be a good option for you if you're looking for more of a budget-friendly axle-back that still delivers with stainless steel materials and still has more of a standard muffler design. The majority of the less expensive axle-backs out there are muffler delete systems, but the Street Pro Touring Axle-Back doesn't fall into that category. So if you're looking for a system that wakes up the GT, but that isn't too loud and doesn't have drone, then you're in the right place. This is a 409 Stainless Steel Axle-Back, like I mentioned earlier, and it also is mandrel bent. It's four-inch polished stainless steel tips, but Pypes does also offer this axle-back with black powder-coated stainless steel tips instead, if you like that look better. These systems are going to differ in price slightly, but I'll talk more about that in a minute. And I always say this, but stainless steel is always a great option for the cars that see all different types of road conditions, because it offers great corrosion resistance. The sound that this axle-back offers is what I consider a smooth sound. It's not raspy and loud but more deep and smooth. It's not loud just to be loud. Pypes was looking for a system that provided a deep, aggressive sound with no drone. So when you're on the throttle you have a different tone than when you're off. Off the throttle, you're looking at a more mellow sound from this axle-back. Overall, this is an axle-back that doesn't have a ton of raspiness and popping to it. I will say though to keep in mind that this can get even louder with the mid-pipe and headers. With that being said, I'm going to give it a solid three out of five on the loudness scale. At the end of the day though, no matter if you love the sound or hate it, it really all depends on what you're looking for and what you like. And luckily, there are quite a few options out there when it comes to axle-backs. When we start to look at price, like I mentioned earlier, this axle-back is on the more budget-friendly side of things. If you like the look of the polish tips here, you can expect to spend between $400 and $500, while the system with the black stainless steel tips is about $30 more. Either way, both systems are very affordable when you compare them to other offerings. But, just like I said, with every axle-back, if this isn't what you're looking for, feel free to check out some other options since there is a lot to choose from. You're gonna be looking at the typical cut and clamp design with the install for this axle-back, since you need to cut all S550 axle-backs. I'm gonna call this a two out of three wrenches on the scale, but just because the cutting that's involved. It's nothing difficult but I just recommend some eye protection and a fresh blade to make the cutting easier. Overall, you're looking at about two hours to get this all done. A lift would certainly make things easier for you here, but the job can be done on jack stands as well if you don't have access to one. Cutting the factory axle-back isn't hard. Just be sure to measure twice and plan to mark where you'll be cutting so you don't make a mistake. The new axle-back is gonna come with new clamps for you, so you don't have to worry about that. When you go to install your new setup, it'll probably be easiest to leave everything loose until you have it all lined up, and then tighten it down. Overall, the Pypes Street Pro Touring Axle-Back is a good option for someone looking for a stainless steel system that's gonna help with exhaust tone but that isn't gonna be too rowdy. This is a mandrel bent system with four-inch polished stainless steel tips or black powder-coated tips. You can check this axle-back out more online for yourself, and for all things Mustang, keep it right here at americanmuscle.com.

    Deep Aggressive Sound. A Pypes Street Pro Touring Axle-back System will add a deep aggressive tone to the sound of your S550 GT's exhaust with absolutely no drone. Pypes Street Pro Touring Mufflers were designed to provide an aggressive exhaust note when goosing the throttle and a pleasant mellow sound while cruising, with no interior drone.

    Stainless Steel Construction. Pypes manufactures its Street Pro Touring Axle-back Exhaust from 16 gauge 409 stainless steel tubing for long lasting durability and excellent corrosion resistance. All Pypes Exhaust Systems feature smooth mandrel bent tubing to eliminate any power robbing kinks. Complete with a set of brightly polished stainless steel 4" tips, this Axle-back also adds bold muscle car styling to your Mustang.

    Cut & Clamp Installation. The installation of this Axle-Back Exhaust system requires cutting and removing the factory muffler assemblies and clamping the new muffler assemblies in place. Clamps and instructions are provided.

    Application. This Street Pro Touring Axle-Back Exhaust System with Polished Tips is specifically designed to fit 2015 to 2017 GT Mustangs, including both the Fastback and Convertible models. Cutting the factory exhaust is required for installation.

        Hello Can you tell me how much dezibel is there? Thanks.

        • The Pypes Street Pro Touring Axle-Back Exhaust will have an exhaust decibel level that varies somewhat from car to car. In addition, all mods done to a car will have an effect on this. On average we see around 80-95db, but again there will be a variance in this depending on a number of factors, and from car to car.

        How loud would this be with an H Pipe? Also, would adding an H Pipe introduce rasp to the sound or would it still have that clean, deep, muscle car sound?

        • Adding an h-pipe will likely increase the sound depending which h-pipe you are looking at specifically. Since sound is subjective, it would be difficult to provide an accurate description of how loud this axle-back would be, we apologize. Additionally, H-pipes generally produce a clean, deep muscle car sound without the rasp. If you are interested in the raspy exhaust note, we would highly recommend a x-pipe.

            Does just what I was hoping for.

            It took me longer than expected to install as one side of the axel back pipe was more oval than round at the end. Had to use c clamp to hold correct shape to then instal. I felt the welding was not as good as it could be , or on par with the factory units. Performance wise, they are nice and deep sounding. Transforms the experience when you put your foot down. True to other reports, no drone at all which was so important . I kept factory resonator. Overall worked out great on my car, very happy.

            Sweet Sound

            Got these to replace a muffler delete Axel Back cause it was too loud. At first these seemed quiet (by comparison) but once the sound of the others faded from memory I really started to appreciate the great balance between pushing the RPM's and cruising down the interstate. It has the perfect balance between a aggressive performance sound without being obnoxious on trips. One negative; one of the pipes apparently got "bent" on the end and it took some time to get the opening hammered out so it would fit over the cars pipes. Once I got past that the install was simple since I had already cut my pipes for the previous axel back install.

            Very loud when paiered with an H-pipe

            I had these installed today replacing my stock mufflers. I had already removed the factory resonator a while back but was looking for a deep and slightly louder tone. These gave me a great rumble with a deep tone, but far too loud when paired with my H-pipe. I will be going back to the shop tomorrow and try to have my resonator reinstalled. Hopefully this will give me a good outcome.

            Nice Axle-backs

            First of all, I have these Pro Touring axle-backs paired with catless longtube headers and resonator deletes on my 2017 GT auto, so my setup is a lot louder than what these were designed for. I'm sure with cats or resonators at least, they would be perfect. But on mine, they are extremely loud lol. I love the tone, but cold starts are pretty brutal. Once it warms up though, the rpms drop and it becomes bearable. The plus side is that they have absolutely NO drone as stated, up to 70mph on the interstate. And I daily these 60 miles a day. The installation wasn't bad at all for me as it was my first time cutting off the stock 15-17 mufflers. Fit and finish were great.

            Excellent quality and sound...

            The fit was perfect and the sound amazing. I will say, louder than I thought but I do have long-tubes and no cats, so that doesn't help in the loud department. Gained a little in hp/tq in the wheels but not much. The quality and sound is what I was looking for. Almost 440rwhp and 390rwtq SAE with this setup. Also, took away the annoying drone at around 2200rpm.

            Excellent bang for your buck!

            As many new S550 Mustang owners probably have done I agonized over 100's of exhaust videos wanting to pick just the perfect one. I met a few locals who had amazing sounding setups from a range of companies and then stressed even more as some were just too loud for my taste, others so subtle that I couldn't understand why bother spending the money..I also realized quite quickly I was going to be saving for quite a while as it seemed easy to spender over $1K and in many cases nearly $2K!!!! Enter the Black Friday sale, and the Pypes touring axle back. For me, my wallet, and my ear, the perfect compromise between sound while not breaking the bank. They arrived quickly, packaged well, and appear to be high quality. Nice polish, great looking welds, and I like the fact the tips aren't welded on so I can change them if I'd like. Install was easy following any of the great online tutorials... highly recommend! Note - I paired mine with a cut-n-clamp X-pipe and it sounds even more glorious, maybe 15 louder, still no drone whatsover, cruising just a bit louder than stock, goose it a bit and you'll know you have a beastly V8 but won't raise the dead 3 counties over!

            It is really fun and aggressive, but watch out if you have a set of headers and mid pipe it’s going to be really loud and will have drone

            Pypes Street Pro Touring Axle-back are awsome!

            Bought these to replace a non branded axle back exhaust from another store. It was too loud and drony (I have an automatic). The Pypes Street Touring fit perfectly over the cut from the previous axle back. The the sound is just perfect for me. Nice aggressive sound outside but quiet inside. Now I can hear my subwoofer, and I can have a conversation with my passenger, and no drone! Fit and finish is very good. The polished tips look awsome. Thank you Pypes, thank you American Muscle!

            Loud Good Bang for Your Buck

            Bought these because i needed an exhaust system that was not as loud as Roush. Good sound level. Sounds like thunder is coming down the road when you floor it. Sound is increased with an X/H Pipe

            Best bang for the buck

            The mufflers were well constructed, the welds were as good as any I have seen. when the stock mufflers were removed the Pypes exhaust was installed with no further adjustment. The stainless exhaust tips slid on the mufflers and clamped in place making for a very easy install. The sound is just what I was looking for, noticeably louder than stock but not obnoxious, just a nice deep rumble. At highway speed there is no drone. If you give it a little gas it perks up just to let you know its still there. I am satisfied, and would purchase again.

            Bad to the bone!

            I was debating on getting these Pypes Pro Street Axel back vs the Roush Axel backs. I then decided that what I really wanted was something to make my 5.0 California Specials sound different then Every other mustang in my area. I sure am glad I got the Pypes they sound beautiful and mean. Not too loud and not quite at all, just puts a big smile on my face while shifting gears!

            Overall Happy

            I have a new 17' convertible gt. I wanted an exhaust that sounded like the a mustang should have sounded from the factory. Being a convertible I didn't want a system that was too loud and No Drone. I've had this kit a week and love it. The sound is perfect. Deep rumble at idle. Mid rpm sounds amazing and up high it sounds really good. While cruising it is almost stock quiet and has absolutely no drone like Pypes advertises. The reason I gave 4 stars is fitment. The right side needed quite a bit of bending because it hung an 11/2" lower than the left. I also cut the muffler exit pipes 2" because the tips stuck out too far from the diffuser. Quality of materials is great sound is great price is great but workmanship off a bit. If you don't mind a little mechanizing these are awesome

            Great Sound, Great Price, Easy Install

            This exhaust will give your GT that nice rumbly sound when you put your foot on the gas (and on a cold start). However, when you're just cruising, its just a tiny bit louder than the stock exhaust. I wouldn't even call it louder...you can just hear the rumble a bit better. But I'm telling you as soon as you put your toe on that accelerator it opens up. It is a great muscle car sound coming from an axle back under $500. What more could you want? Did the install myself. Pretty easy if you have jack stands, a sawzall, and some patience. I did have to file down one of the stock pipes to fit the new exhaust but that only added about 15 minutes of work.

            Great sound

            If you want that deeper rumble without shaking the pictures off the wall this is a great option. It is noticeably louder than the stock exhaust, but not so loud the neighbors are going to be upset. The real difference is the lower note and tone which is how the car is supposed to sound. I couldn't believe how easy the install was. Once the car was on jack stands it was 30 minutes and we were done.
