    performance exhaust for 4.9

    I was wondering if anyone out there is running any aftermarket catback; I don't want ones that sound obnoxious or drone on the highway, but still sounds throatier than stock. I was thinking perhaps flowmaster delta series muffler, although I don't know what series would be the best. Any input would be appreciated.

    I think that the 50 series will do you well.
