How does the SwitchPath system change the sound?

The system uses a valve controlled by the included remote. With the valve closed, the exhaust flows through a muffler for a quieter, sophisticated tone. Opening the valve bypasses the muffler for a more aggressive sound.

What is the purpose of the included downpipe?

The system includes a 3-inch resonated downpipe. This is part of the complete cat-back system and helps manage exhaust flow and sound before it reaches the muffler and valved section.

Are the exhaust tips adjustable?

Yes, the 102mm double-walled exhaust tips are individually adjustable. This allows you to set how far they sit within the bumper cutouts to your personal preference.

Product Details

You get a complete cat-back exhaust system with a downpipe and remote in this AWE Tuning SwitchPath Exhaust. This system lets you change the exhaust note from sophisticated to aggressive with the push of a button using the included SwitchPath Remote. It's designed for the 2017-2018 Audi A4 Quattro and A4 models.

The system includes a 3-inch resonated downpipe with a stainless steel flex section. The driver's side features a 3-inch valved straight pipe, while the passenger side has a 2.5-inch pipe with a muffler. This setup allows for instant sound changes. You might hear a slight valve rattle on cold starts, similar to factory systems, which goes away after a few minutes. The exhaust is crafted from U.S.-sourced T304 stainless steel with CNC mandrel bends.
