Aftermarket Exhaust Question For 2010 Silverado

[noupf]

Hey guys, I was thinking of getting an aftermarket performance exhaust / muffler for my 2010 ext ltz with the 5.3l , but i've been out of the loop for a number of years reagrding performance aftermarket parts and such, so i'm not sure whats good or not anymore ( borla, flowmaster and so on ). I dont want anything too loud......Something with a nice low grumble.....a little bit more agressive and louder than the stock, but not something too obnoxious. Any reccomendations or experiences?

 

Thanks !
