Product Description
Presenting the first AWE SwitchPath™ configuration for BMW to incorporate patented drone-canceling 180 Technology®. No drone, minimal bends, maximum flow, and push-button attitude. The SwitchPath™ Exhaust is comprised 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 factory mid pipe, the precision X-pipe immediately helps smooth the S58 of its rasp, deepening the tone before its 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 automatic vehicles. 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™.
Important Fitment Notes That You Should Read:
- 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.
- Convertibles: AWE's Exhaust suite for G8X is not guaranteed to fit on convertible models due to additional factory bracing.
- Valances: AWE Exhausts are confirmed to fit stock and M-Performance valances.

S&B 75-5133D COLD AIR INTAKE FOR 19-20 DODGE RAM 2500/3500 6.4L HEMI (DRY)
The manufacturing and engineering was great. You can see the quality in the final product and the installation fit was perfect. It took me 30 minutes to do the install. Definitely woke the engine up and gave it a nice rumble but not over bearing on acceleration. Not enough miles on it to know if the fuel mileage will increase but overall very satisfied with the product.
