    Review & Install Video

    The AWE SwitchPath will be a premium cat-back for the S550 GT owners out there looking for an active system giving you the ability to control both your volume and your tone through the included remote control. Now, prospective buyers can look forward to some extremely high-quality components here, including the materials which is going to be 304-grade stainless steel throughout, along with those chrome silver tips for the $1,600 to $1,700 price point. Your installation will be a little bit more difficult compared to your traditional cat-backs, because there is a small amount of wiring to get your SwitchPath valve hooked up. So I am going to knock it up to a soft two out of three wrenches on the difficulty meter, with some more detail to come later in the video. So even though AWE is kind of this new kid on the block in the land of aftermarket Mustang exhausts, they're certainly not new to creating systems, as they've been doing so for other high-end cars for almost 20 years now. Since their introduction into the Mustang world, they've quickly become a hit with the S550 crowd, thanks to their exceptional build quality, which we've kind of already covered, their aggressive tone. H-pipe configuration, by the way, which is a bit of a rarity in the premium category. Then, finally, their SwitchPath technology here, which is the latest entry into the active exhaust market. AWE's approach is a unique one when compared to other options out there from Ford Performance or Roush, for instance, which utilize an actuator a little bit closer to the physical muffler, dramatically changing up the sound. AWE here, on the other hand, well, as you can see, they mount their valve, or their actuator, on the H-pipe portion, and uses the open or closed positions to change up the sound, using the included remote control. But let's break down the sound profile. With the valve completely open, you're essentially getting a Touring cat-back from AWE, incorporating that H-pipe. It is still pretty aggressive overall, good enough for a strong three out of five, or one to Wake the Neighbors scale. Now, with that valve fully closed, on the other hand, you're essentially eliminating the H-pipe and giving the car more of the straight-piped kind of feel. Now, I'll be the first to tell you, guys, you aren't going to be getting a huge difference in volume like you would with those Roush or Ford Performance systems. Instead, the difference between the two systems, or options, with the AWE cat-back is going to be minor in regards to volume. But you do pick up a little bit more of an aggressive tone when you eliminate that H-pipe. Now, even though the difference between the two valve openings or positions isn't exactly huge, per se, it is good enough to knock that three out of five up to a four out of five with the valve in that fully closed position. As I just pointed out, the exhaust characteristics do take on a little bit more of an "unruly vibe," I like to call it. It kind of gives you more of those crackles and pops coming down off the revs or in between shifts, which is something I've always enjoyed about this particular system. Another thing I do really enjoy about the AWE stuff is that they take the road less traveled here in regards to your mid-pipe configuration, giving you this H-pipe in place of an X-pipe. Now, the reason I say that is because most, if not all cat-backs in this price range do utilize an X-pipe, which does help attribute to a more raspier note overall. Whereas I think the H-pipe here is going to help keep things a little bit deeper in regards to overall tone, and it is something I think a lot of S550 owners will enjoy. But moving inside the car, on the other hand, you can expect a completely different experience, thanks largely in part to AWE's proprietary technology, known as their "180 Tech," which the company incorporates with ta good portion of their mufflers, or "resonators," as AWE likes to call them. Now, this patented tech is AWE's way of determining these unwanted frequencies, otherwise known to you guys as "drone," and then designing the system in a way to cancel this bad stuff out. But shaping that deep muscle car sound, you've got a few things working for you hear. We've already covered the H-pipe. But AWE also does include two bullet-style resonators here, midstream before everything does pass through their Touring-style resonators. No. That was not a mistake. AWE insists on calling these things "resonators" and not "mufflers." I just wanted to clarify that for you guys. Now, the Touring resonators are a straight-through by design, which AWE claims will help free up the exhaust a little bit, give you a little bit more power, and they are loaded with the 180 Tech that we've already mentioned. But enough about sound, let's break down the quality and construction of the AWE system. As I pointed out earlier, you're going to find an A-plus build quality and materials here, with this and other AWE systems. The USA-made cat-back uses nothing but premium-grade 304 stainless steel. Believe me when I tell you, guys, this is how you want to see things built when you're spending this kind of dough on a premium cat-back. The guys at AWE have done a great job, and it really does show when you unbox this thing for the very first time. But going even further with the construction, you've got three-inch mandrel-bent tubing, essentially, from tip to tip here with this system, leading through those bullet-style resonators before going through the Touring resonators, all exiting out the four-inch chrome silver tips etched with the AWE logo. Now, as far as price is concerned, well, listen guys. I know the $1,600 to $1,700 price tag is a bit hard to swallow for most Mustang owners out there/. But you have to compare similar products, and then you'll see that the AWE stuff is on the more affordable side of things compared to other active systems in the category, or on the site for matter. The Roush, for instance, it's going to hit you for nearly $2,600, and that's only an axle-back. So these are some of the things you have to consider when shopping for an active system. But getting into the install, and again I'm going middle of the road two out of three wrenches on the difficulty meter here. Because, yes, there is some light wiring needed for the SwitchPath valve. But it's very basic power and ground-type stuff. So a few hours from start to finish, before you're up and running here with the AWE cat-back. Basic hand tools, guys, including a socket set, in addition to your wiring tools. I'm talking wire strippers, soldering iron or crimpers, whatever you like to use. I always recommend a little spray lubricant to help you with some of those bolts, in addition to the rubber hangers. Then, last, but not least, a lift, jack and jack stands, or race ramps, whatever you have access to. Getting started, you have to remove that factory exhaust system. So grab your 15-millimeter socket to remove the two band clamps closest to the resonator. Then, remove the two 13-millimeter bolts securing the hangers to the rear subframe, and drop that factory system from the car. Next, disconnect the battery and get ready to route some wires through the trunk and underneath the car, leaving the control box in the trunk area. At this point, you will need to splice the red wire into an ignition switch power wire in the factory trunk area, or factory trunk harness, and then just connect that black wire to a ground. From here, you can start installing the AWE system, beginning with the H-pipe and the SwitchPath portion. Connect the SwitchPath harness and check that it's operational. At this point, you can now work your way from front to back, using the included clamps. Snug these things up, but don't fully tighten everything up quite yet, until the very end, because you may need to move some of the pipes around slightly. Now, you can align the tips in the bumper openings, and tighten up all your clamps, and your installation is complete. Wrapping things up, guys, the SwitchPath from AWE is a beautifully-constructed, unique system that will give you some flexibility with your tone, thanks to that built-in SwitchPath valve, all for around $1,600 to $1,700.

    From Smooth to Aggressive. With just the push of a button you can change the sound of your GT Mustang from smooth to aggressive. AWE designed their SwitchPath Cat-Back with an electronically valved H-Pipe. In the open position the H-Pipe will balance out the exhaust pulses for a smooth muscle car tone. However, in the closed position the H-Pipe will act more like a set of old school straight pipes that will create a louder, more aggressive sound. Besides the SwitchPath H-pipe, this system includes a set of bullet style resonators that replace the bulky factory resonator and a pair of straight-through Touring resonators that feature 180 Technology®. Together these components will give your Coyote powered Mustang a more pronounced sound that is louder than stock without any irritating drone in either the open or closed position.

    Performance and Power. Featuring a clean, non-baffled, straight-through design the AWE SwitchPath Cat-Back not only improves the sound of your GT Mustang, but it will also improve its performance. By reducing back pressure and giving your GT a free-flowing exhaust, you will see increases in both horsepower and torque. AWE has seen gains of 8 hp and 18 ft-lbs of torque to the crank.

    180 Technology®. AWE designed their Touring resonators using their own proprietary 180 Technology® to give your Mustang a smooth muscle car tone without annoying interior cabin drone. As exhaust gases flow through a AWE 180 Technology® equipped Touring resonator, they pass through strategically located ports, and into reflection chambers. Sound waves, carried by these exhaust gasses, bounce off the walls of the reflection chambers. Restricting the size and location of these ports and chambers, will control when the sound waves exit the chambers. The specific timing of when the reflected sound waves rejoin the main exhaust flow creates a 180 degree out-of-phase sound wave that cancels out problematic frequencies.

    T304 Stainless Steel Construction. AWE proudly engineers, designs, and manufactures their Cat-Backs in-house, in the good old USA. This exhaust system is handcrafted from U.S.-sourced CNC mandrel-bent 0.65” wall T304 stainless steel tubing for superior strength and corrosion resistance. The system includes a SwitchPatch H-pipe with two bullet style resonators and features two straight-through resonators that end with chrome silver 4" double walled, slash cut exhaust tips.

    Direct Bolt-On Installation. Engineered to be a direct bolt-on replacement upgrade, this AWE SwitchPatch Cat-Back replaces everything from the mid-pipe resonator to the exhaust tips. This exhaust system with SwitchPath H-Pipe includes all necessary clamps and hangers to ensure a simple, straight forward installation with no modifications required.

    Application. This AWE Stainless Steel SwitchPath Cat-Back with Touring Edition Resonators is designed to fit 2015-2017 Fastback GT Mustangs equipped with the 5.0L 4V coyote engine. This 3" Cat-Back steps up from 2.5", so that it can be installed with the factory 2.5" exhaust system. Does not fit convertible models.

    In terms of installing the remote wiring. The AWE instructions seem to assume that everyone has a premium model Mustang GT that has a subwoofer and an accessory cable powering that subwoofer in the trunk which can be spliced into. I have a base model GT so I do not have said wire. Is there another accessory wire in the trunk area that I can splice into or will I have to look into wiring it somewhere else?

    • For proper installation of the wiring for the AWE SwitchPath Cat-Back Exhaust, I would refer to a wiring diagram to accurately find an ignition-switched power source in the trunk area of the car, if accessible, and then a good known ground source for proper installation. If there is not a proper ignition-switched power wire in the trunk of your car, it would be advised to find the next closest circuit that would not interfere with the circuit that would be spliced into.

    Exhaust installation aside, how is the installation for the "switch" mechanism? Is there anything in the exhaust that gets hooked up to power to enable the "switch" between quiet and loud?

    • The AWE SwitchPath Cat-Back Exhaust w/ Chrome Silver Tips Would utilize a solenoid that needs power and ground in order to function.

      Love this system

      I had the MBRP Race cat back for about 2 years. Honestly I got sick of the drone and one of the baffles broke in the muffler and i would rattle from time to time. I got this system because I wanted to make it quieter while pulling out of the driveway in the morning. I have had people say that inside the house it is very noticeable when its in the different modes. When I looked at other sets up (roush and varex) i either didn't like the set up or the cost (roush=$2600 ). As for the sound. It is MEAN in the "off" (quiet) setting and just gnarly loud in the "on" (loud) setting, but a little quieter than the Corsa Extreme w/out the rasp). The difference is noticeable, but not going to be night and day. cold starts have a lot more "lope" sound in loud than the quite mode does and while driving the loud mode crackles and pops more as well. Best comparison is that quiet modes sounds a bit quieter than the MBRP Race system (without drone but just as mean) and Loud has a racecar type sound (especially at higher RPMs).

      Big Change!

      Wanted something louder than stock with the ability to make it very loud if I wanted. This fits that requirement but I would say, I wish there was a little more difference between open and closed at certain RPM levels. This is not to say I'm disappointed though. The quality of this system is extremely high! The sound makes my stock GT 5.0 sound VERY aggressive! Even the price is fair when you compare other systems with the capability of switching exhaust paths from inside the car. Took longer to run the wiring and find a 12 volt source that was switched than anything else.
