I have a 2009 dodge ram hemi 5.7 and about a year and a half ago i bought the magnaflow duals for it and replaces the single side exit. For a long time it sounded really nice and it got louder as it got older but for some reason it got quiet and i can't figure it out. It sounds alot lamer on acceleration sometimes theres almost no noise at all ;/. Anyone know what may be causeing this please throw me some suggestions cause i have no idea and its really disapointing me. If i need a new exhaust what do you all suggest, Im tryn for the loudest i can get with the muffler still on. Alot of people say do straight pipes but i can't because were i live we need to pass emmission testing so I cant do straight pipes. Would flowmaster be louder?
