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.

    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.

    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).
