[Intercooled]

I was thinking the same. I believe the touring is more subdued and a bit louder than stock. The sport is deffinitely more robust and muscle car sounding. To my ears, from the internet clips, the sport seems a bit loud. But its all what your looking for. I'm not really into loud rumble up the neighborhood sound anymore. I like a slightly agressive rumble. My concern would be that the touring isnt loud enough. I wouldnt want to spend the money to not have have any real difference from stock. Hopefully someone can verify this for us.
