Here is my 64 Barracuda while still working on her with transplanted 273 commando & full accurate 273 hi-po set up minus resonator. Fit is exceptional on their pieces. Made my own pipe with turn down from muffler to appear as original 2bbl setup for correct 64 look. Rumbles but actually like better without resonator. Also had factory exhaust manifolds acid ported. Can’t here difference but can feel it in seat of pants.
And yes ribbed radiator hose was eventually replaced.lol
