Like it says I'm looking for some one locally that has a Mufflex sys on there truck so I can here it in person, the YouTube videos just are not doing it for me. Today I went to a local shop in Kenner called Southern HotRod and all they install on there cars are Corsa cat back sys. The owner's wife was kind enough to take for a drive in her 2008 that had a Corsa cat back sys and it sounded really nice and was vary quite in the cab. The owner is looking into just getting me a muffler from Corsa that will work the best for the 09's. Anyways I would love to here the Mufflex sys in person to make up my mind so if you live in the New Orleans area give me a shout so I can here your truck, thanks...
