My friend just had some of the "red" DB series welded into his 99 GT. He has a bassani catted x in front of them. They sound absolutely awesome, and drone isn't any worse that what you'd get from a stock system. If you like Borla/Magnaflow as far as tone, and want a muffler that has even less drone than they do, these are your mufflers. I'd call it a gentleman's exhaust.
