Armytrix truly is one of the best exhaust systems you can get installed to your ride. Especially if you are looking for a more aggressive, head-turning sound. The stock exhaust (see below) produces it’s own pops and bangs on this S3 which isn’t a bad sound at all. However, if you’re not after subtlety, be loud and proud with Armytrix, we say.
