Check my sig for what I've got. A general statement someone made of a Magnaflow being louder than stock is not necessarily true - it all depends on the unit and the size. I replaced my stock res with an oval Magnaflow part # 14215 which is pretty well a direct replacement fit. It sounds awesome (a wee bit louder than stock) and is straight through. After searching for good music on the radio the other day, I got fed up, turned it off and just listened to the exhaust - sweeet music to my ears it is ..
