For Audi S5 4.2L owners seeking an even more aggressive sound in addition to our Track or Touring Edition Exhaust systems, we offer our Non-Resonated Downpipes. AWE Tuning Non-Resonated Downpipes eliminate an additional set of resonators from the car to produce a louder and deeper tone to the exhaust note.
When AWE Tuning Non-Resonated Downpipes are paired with a AWE Tuning Audi S5 4.2L Touring Edition Exhaust System, your Audi S5 will produce a subtle exhaust note around town, while become much more pronounced during higher RPM operation and aggressive driving. The AWE Tuning Non-Resonated Downpipes paired with the AWE Tuning Audi S5 4.2L Track Edition Exhaust System produce an outright roar -- they are only recommended for those who like it loud.
