I have Bose in a number of my cars (the top end option with sub woofer, extra speakers etc.) and have found it pretty darn good. It is very good (especially in surround sound) in my XTS, and while I agree it doesn't typically 'drown' out the exhaust on my Porsche, when I am blasting the symphony in flat 6 I wouldn't want the Bose to over power it. IMHO that is one of the pluses of a performance exhaust system. I am sure the Bose in my C7 will be perfectly good with additional speakers and woofers in that small enclosure, and definitely don't want it over riding my Performance exhaust when I am driving enthusiastically.
