single cat on 350
I assume all 350's are like this so i guess i am asking why GM didn't put dual cats on the 350's?
thanks

Bad assumption. They aren't all like that.
GM did.
Just not in 1987...

no not really, dual cats was an option. i have a single cat on my 89 but there was an option for dual cats.
but if you look at it as costs for you a single cat car is cheaper since you only have to buy 1 cat and not 2 plus there are more shortie direct fit headers available for a sigle cat car. the 2 cat cars still end up with a single 3 in piping before the muffler so roughly will flow the same when modified.
if go with long tube headers and true duals whether you had 1 cat or 2 to begin with wont matter.
typing with 1 hand now thats a bitch
took me forever to type this. haha

I have a 350 and dual cats, it's part of RPO G92. (I forget the dual cat RPO by itself.)
