I've got a 92 f250 351w, right now it's all stock minus the cat (no cat right now). I've got a leak in one of the manifolds and it got me thinking about redoing the whole exhaust system. Eventually I would like to do a complete rebuild on the truck but it is going to stay stock for awhile. I'm wondering if I should stick with manifolds or go to headers? And I'm not real sure what to do about the rest of the exhaust. I want it to have a mean growl to it but nothing too obnoxiously loud that it is going to set off car alarms.
