If you were my neighbor I would hate you! It sounds like you need a muffler! The drone would make my head explode! You cant hear you music or have a conversation with you passengers, especially if you are on the highway.
But when I was young, I probably would have thought the no Muffler sounded Bad Azz.
If I was you (I am know , I am not) I would look for a cheap Catback system. it seem like there is a trend of guys selling their GTI and there is a ton of aftermarket parts at half the price. Either that or just reinstall your muffler minus the resonator.
Just my $.02.....
