Hey guys! Today we’re driving a modified B7 Audi S4 and what’s the first thing we noticed?! It sounds AMAZING! With Audi’s naturally aspirated 4.2L V8 under the hood and a Milltek catback exhaust system, this modified S4 is one of the most angry sedans we’ve ever driven on the show. The owner has made changes to the suspension in the form of coilovers as well as a set of brakes from an RS4. If I didn’t have a thing for good fuel economy, I would totally have this as a daily! Enjoy.
