I got bored last weekend and thought I would make a video for people thinking of doing a custom exhaust since many of the kits out there are pretty pricey and there isn't make example vids out for the B5 S4. I have a 12 inch resonator with Magnaflow muffler and 3 inch piping. You will notice at one point the piping is hang a little lower then what I like but I'm sure that can be fixed. The kit was around $700 installed. Took about 6 month of daily driving before it really broken-in. Still from within the car it is pretty quiet thanks to Audi's sound dampening. Any ways enjoy... The video is a little on the quiet side just to warn you. And it is in HD if you are a HD snob like myself.
