Need muffler help
Hey guys, trying to get ready for this season. Does anyone know the stock muffler size on a 2003 gt and if a 4x9 inch 18 inch long muffler would fit in. I have 14 inch magnapack system right now but looking to put magnaflow performance mufflers to keep noise down and police at bay.
