My 2010 GTI was the last year of the "growler" - a pipe that bleeds off a small amount of boost from the inlet pipe and feeds it into a resonator up against the firewall. Absolutely worthless - many folks (including me) ripped the damned thing out and replaced with a Tiguan pipe. Saves a few pounds, cleans some plumbing out of the engine compartment making access to your oil filter MUCH easier, improves the throttle response a little and lets you hear the actual engine noises. VW must have agreed - 2011 GTI's don't have them.
