Had muffler shop Install new flowmaster series 40 mufflers on my 2012 v6 camaro. Awesome sound ! The problem am having is when am decelerating and getting on in seems that the camaro is stumbling and getting vibration throughout the whole car like its struggling to excelerate. went to dealership to check if I have any throttle problems and they found nothing wrong with car. called flowmaster and they said that they have the proper kit for camaro and that they don't recommend just replacing mufflers with stock flowmaster series 40 mufflers but use kit instead. Has anyone had this issue? The mufler shop is not being very much help. You know no service after I have your money.. any ideas or suggestions? I hate to go back to stock mufflers. Thanks

hmmm... did you go over the whole exhaust to make sure nothing was touching? It could possibly be hitting something causing vibrations producing false knock which will pull your timing giving you that feel you described. I say get under the car and check for anything touching.

Ok had everything check out by muffler they adjusted rear hang bracelet by bumper. The issue still continues feel vibration throughout whole car at high speed on highway for about 3 sec then it go away and comes and go wehn accelerating or decelerating. Will check with dealsership to see if its a defect in car .. my last resort is go back to stock mufflers.
