The other option in the same price range is Hooker SuperComps. They are notorious for poor fitment, but they are tuned length, whereas the D452’s are not. Something to consider. My Hooker Comps fit real nice on my low deck 67 B-Body combo. I would recommend them for fitment. But they are a 1-7/8” / 3” setup. I’m about to tug on the 700hp lever with them.
