Turn up your speakers, plug in your headphones, Winding Road has made an in-depth exhaust note comparison video! We drive the 2011 two-door Volkswagen GTI with the stock exhaust against a 2010 four-door Volkswagen GTI with an aftermarket Magnaflow cat-back exhaust (both have six-speed manual transmissions). Which do you prefer, and what are your thoughts on adding aftermarket exhausts to new cars that some may feel are too quiet?
