armfwi Posted June 6, 2008 Report Share Posted June 6, 2008 Hi guys, What size inlet/outlet size muffler would I need for my 94' DeVille? The exhaust is 100% stock. I was thinking it was 4.25 in/out, but I am not sure. Also, I am looking for a VERY QUIET muffler. Does anyone know what a good muffler would be? Nothing spectacular... just something quality and super quiet. I want to make it as silent as possible (no stalker). My current muffler has developed several holes and is now loud as hell! Thanks!
