If you like hot hatchbacks with all-wheel drive than you know the S3 is the car of the moment. It comes from a long line of competent, fast cars and brags about its 300 horsepower and 0 to 100 km/h time of under 5 seconds.
Audi made a great job with the stock exhaust by offering a butterfly flap system. The S3 can be both speedy and discrete. It will get under your skin and it's for this very reason that for some stock is not good enough. That's why a German specialist company called Bull-X developed their own cat-back system.
If you've ever wondered what goes into a custom exhaust's mufflers or simply want to upgrade your brand new Audi S3, you definitely need to check out the video below. Custom exhaust systems are much simpler and don't have the catalysts that are needed to filter exhaust gasses. Steel wool and perforated piping is there more for noise regulation than anything else.
