SwitchPath™ Valved Exhaust:

Featuring AWE's patented drone-canceling 180 Technology®, the AWE SwitchPath™ brings no drone, minimal bends, maximum flow, and push-button attitude. The SwitchPath™ Exhaust is composed of 3-inch U.S.-sourced T304L stainless steel, a precision x-pipe, and a valved SwitchPath™ muffler tuned specifically for the S58. 

Beginning after the factory mid-pipe, the precision X-pipe immediately helps smooth the S58 of its rasp, deepening the tone before it's refined further by the bespoke SwitchPath™ muffler in the rear. 

The closed valve experience

When the valves are closed, the SwitchPath™ Exhaust produces a refined, aggressive howl while remaining full-bodied and powerful – no congested, metallic sounds when on the throttle. At cruising speeds, interior acoustics are close to stock with no drone at cruising speeds. AWE SwitchPath™ tech also responds perfectly to the many transmission settings and shift points in the G87. Drop the hammer with the valves closed and SwitchPath™ sings a proper M anthem. If you were to leave the valves closed at all times after equipping SwitchPath™, we wouldn’t blame you — it’s that good… all of the time. 

The opened valve experience

Open the valves and the S58’s roar is uncorked. Sport and Sport+ modes achieve the ultimate contrast in behavior when compared to comfort driving modes (valves closed). In Sport mode, the exhaust note is powerful, clean, and aggressive. In Sport+ mode, the same aggression applies… but with grin-provoking burbles.  Thanks to the precision X-pipe, the rasp is still kept in check while allowing the exhaust note to reach full aggression.

If you’re looking for the best of both worlds (i.e. drone-free, clean aggression), and want to retain your factory valve behavior all while gaining peace of mind (i.e. emissions compliance), look no further than SwitchPath™. 

The Track Edition:

AWE’s Track Edition takes all of the precision engineering and performance of its SwitchPath™ counterpart, minus the valved muffler in the rear. The result is a constant “valve open” mode, at an affordable price. If you’re craving rich and rowdy tones at all times, and a hefty 13 lb weight savings, this is your dose of steel. 

The Track Edition Exhaust, also 50 state legal like its SwitchPath™ sibling, comes complete with AWE valve simulators to accommodate your factory exhaust valve motors. Happy ECU, happy life.  

Note: This version is known to get rowdy, and may be too much for many. For that reason, this particular version cannot be returned due to sound preference. Prepare yourself (Sport+ mode can be pretty raucous)!

The Non-Resonated Performance Mid Pipes:

Ditch the factory mid-section and replace it with two 3”, non-resonated mid-pipes designed to up the ante in the aggression department. Mate the mid-pipes to the SwitchPath™ or Track Edition Exhausts if you prefer the party to start right behind the factory secondary catalysts. 

Very important fitment notes (please read this too):

• Mid Pipes: AWE’s Non-Resonated Performance Mid-Pipes are designed to be paired to AWE Exhausts only. Due to varying cut points, they’re not guaranteed to work with another manufacturer’s exhaust configuration.
• Exhausts: AWE Exhausts feature inlet adapters to mate to the factory mid-section. When pairing AWE Mid-Pipes to the SwitchPath™ or Track Edition Exhausts, the aforementioned adapters are not needed. Due to varying cut points, AWE Exhausts are not guaranteed to mate with another manufacturer’s mid pipes. 
• Valances: AWE Exhausts are confirmed to fit all factory valances.

WHAT IS 180 TECHNOLOGY®?

AWE's patented 180 Technology® works a little something like this: As exhaust gases exit the engine and flow into an AWE 180 Technology®-equipped 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.  Depending on the sound requirements of each vehicle, AWE acoustic engineers adjust the size and location of the ports and the chambers.  By controlling the size and location of these key elements, we also control when the sound waves exit the chambers.  The specific timing of when the reflected sound waves re-join the main exhaust flow creates a one-hundred-and-eighty-degree out-of-phase sound wave that cancels out problematic frequencies.

CONSISTENCY THROUGH CHANGE.

AWE 180 Technology® is not on a “one size fits all” concept. Rather, AWE engineers design sound cancelation resonators based upon the specific acoustics generated by vehicle types, thereby ensuring perfect sound, every time. It’s one of the reasons AWE exhausts have earned a reputation for the perfect tone, regardless of application.

WHAT IT MEANS TO YOU.

The result? The removal of unwanted tones in all AWE 180 Technology®-equipped exhaust systems. The sound produced by this formula is the perfect, signature note. Unlocked performance and spot-on tone, every time.
