Audi S7's

factory exhaust leaves a lot to be desired. In addition to being a performance car, it has to be a luxury car, too, meaning it can't be too loud for people who don't want to hear the engine all the time.

For those of us that prefer to hear the true rumble of that 420-horsepower V-8 power plant 24/7, Milltek makes a perfect upgrade. It deletes the catalyst and the resonators, resulting in a noise more akin to a muscle car than a German luxury sedan.
