I found one of those header style exhaust manifolds off of an 86 Aerostar 2.3! I am going to go purchase it this week sometime and run true dual exhaust. I will let you all know how it works out. Now, I am looking for some opinions on what kind of exhaust I should put in my N/A 2.3 to get the deepest most 5.0 like sound out of it. (I know it is never going to sound as good as a 5.0, but you can get it close...ish) Should I use 2.25" or 3" exhaust. Is 3" exhaust going to hurt more than help? Also, what type of mufflers should I look into putting on to give myself a throaty sound? Flowmaster, MagnaFlow? I know this is a lot of questions at once, but any help would be appreciated. Thanks in advance.
