1970-72 Monte Carlos Did all cars with Duel Exhaust regardless of engine size received rear exhaust resonators?
Exhaust Resonators from the Factory

The '70 402 I bought new in '70 had dual exhausts with resonators on both sides. I removed them in '73 when I replaced the stock mufflers with Blue Walker glasspacks - BIG sound difference!

My California 70 Malibu 350 4 barrel with factory dual exhaust has them still on from GM.

I believe all 1970-1972 Monte Carlos equipped with factory duel exhaust regardless of engine received exhaust resonators at the factory.

according to Gardner Exhaust yes they did , we installed them on a 71 SS we just completed , but i have never seen an original exhaust on montes we parted so i would say maybe yes
