Hey Guys--I purchased a 2000 SS Camaro Convert last year and it already had the Corsa exhaust on it. It really sounds nice a mellow until you light it off and then it will make the hair stand up on the back of you neck!

My question is after it is warmed up and traveling at idle speed in the parking lot I pick up this bad sound resonance from underneath car in the back. Could it be the muffler heat deflector vibrating that's making this noise? Has anyone else had experice with this system? Okie.Marv
