AWE SwitchPath Exhaust for 2018-2024 Audi S5 Coupe B9

The B9 S5 Coupe's 3.0T V6 has plenty to say, and the AWE SwitchPath Exhaust lets you decide how loudly it says it. Valves in the system move between a refined, drone-free cruise and a fully open, unleashed tone, so one exhaust covers the daily drive and the back road.

AWE builds this system in-house in the USA from dual 2.5-inch CNC mandrel-bent, U.S.-sourced .065-inch wall T304L stainless steel. Its clean, straight-through design is tuned for flow, and AWE quotes maximum gains of 16 hp and 17 lb-ft at the crank across its B9 S5 exhaust range. Front pipes and a precision-engineered X-pipe are part of the package.

Four 4-inch (102mm) double-walled tips finish the rear in Chrome Silver or Diamond Black. The valves can run on factory valve programming or with AWE's optional handheld SwitchPath Remote, sold separately. It is a direct bolt-on with a factory-like install.

Frequently Asked Questions

What does SwitchPath do?
Valves let the exhaust run a quieter path for cruising or an open path for full sound.

Do I need the remote?
No. The valves work with factory valve programming; the AWE SwitchPath Remote is an optional add-on sold separately.

Does it fit the S5 Sportback or Cabriolet?
No. This listing is for the B9 S5 Coupe. AWE makes separate systems for other body styles.

Which tip finish should I pick?
Chrome Silver gives a bright polished look; Diamond Black gives a darker, stealthier finish.

Is it street legal?
AWE lists this system as 50 State Legal because it does not tamper with any emissions control or monitoring devices; it bolts on behind the catalytic converters. AWE does not publish a CARB Executive Order number for it, and local sound limits vary, so check the rules where you drive.
