Corsa Touring for '99 - '06 Silverado / Sierra 1500 Ext Cab $500
#13
I'm fairly sure it's 3" piping and the touring is the quieter of the two. It has great sound. Very slight rumble at idle and a nice roar at wide open throttle. During normal driving around there is NO annoying drone and is not obnoxious at all.
