Agreed. And, it's stock!I have an 09 GTS.
The exhaust is absolute perfection.
I cannot imagine a better exhaust.
Not too loud, not too obnoxious. It's actually sweet sounding. Even for people who don't like anything other than a standard conservative exhaust.
Its a multitude of things. First, the sport button in the regular GT is not set to trigger the flaps, second, there is no vacuum mechanism installed that would be able to control the flaps. Im guessing something could be retro fitted, but it would be a good deal of work.Do the flaps not work due to a software issue?
