well my 89 SC is bone stock, brand new drive train. just a newer model supercharger off another sc i had. removed air silencer. Was wondering when i get an exhaust job soon, is it worth the money to put on ported manifolds? or should i put it into the intake area? and also what should i tell the shop to do for exhaust? i was thinkin 2.5 inch off the manifolds w/ no cats, 2-2.5 in resenator 1 3" pipe out then split back out into 2.5 through 2 turbo mufflers....does this sound ok? i want something a little louder than stock but not by much.
