69 yenko chevelle

[Keith Tedford]

We bought our COPO Chevelle new and I can only speak for it. This car was very near the end of the production run. It had the standard reverse flow mufflers and no resonators. It is my understanding that these resonator pipes were only used with the NC8 chambered exhaust. Just try chambered mufflers without resonators and you will know why they were used. Our exhaust tips were not rolled, but the usual angle cut. As a matter of fact we still have the old tips. It would be nice to find out when the rolled tip exhaust extensions were used. Was there any particular plant or time frame where the rolled tips were used? Other than pictures, I have never seen them.
