SwitchPathâ„¢ Catback

The AWE SwitchPathâ„¢ Exhaust is comprised of 3-inch U.S.-sourced T304L stainless steel, a precision x-pipe, and a valved SwitchPathâ„¢ muffler tuned for the S58. Beginning after the factory mid pipe, the precision X-pipe immediately cures the S58 of its rasp, deepening the tone before it's refined further by the bespoke SwitchPathâ„¢ muffler. When the valves are closed, the SwitchPathâ„¢ produces a refined, aggressive howl while remaining full-bodied and powerful - no congested, metallic sounds when you're on it. At cruising, interior acoustics are close to stock with no drone. AWE SwitchPathâ„¢ tech responds perfectly to the many transmission settings and shift points of the G87. Drop the hammer with the valves closed and SwitchPathâ„¢ sings a proper M anthem. If you were to leave the valves closed at all times after equipping SwitchPathâ„¢, we wouldn't blame you - it's that good... all of the time. 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 (aka 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. The AWE SwitchPathâ„¢ comes with quad 4.5" double-walled, slash-cut tips available in chrome silver or diamond black. The exhaust also features inlet adapters to mate to the factory mid-section. When pairing AWE Mid-Pipes to the SwitchPathâ„¢ or Track Edition Exhausts, these adapters are not needed. Due to varying cut points, AWE Exhausts are not guaranteed to mate with another manufacturer's mid pipes. AWE's No CEL Guarantee, Perfect Fitment Guarantee, and Lifetime Warranty come standard.
