A local person is parting out a 99 and I inquired about the complete exhaust system. It will be for the 97.
I understand the California vs federal. But it's difficult on the CAT interchange. If my (wife will claim it's hers) 97 is Cali and the 99 is Cali I will only have 1 CAT and the 99 will have two and will not stap?
If we both have federal then it's a go because we both have single CAT systems.
After the CAT it looks all the same.
He mentioned something about square or triangle flanges on back of manifolds for the crossover as a way to tell.........discription on NAPA if accurate states non-carb is 4 bolt flange and CARB is 3 bolt flange. Length is identical
