Cold Start 66 mustang 289 Headers and Exhaust

My 1966 Ford Mustang with the 289 engine. I have Headmen Long Tube Headers, with new pipes 2 1/4" straight no h or x pipe and no cats with 40 series Flowmasters. With a 4B Demon Carburetor. Just installed new GT Steering wheel.

I am trying to imagine how my 65 from craigslist that just had a 289 thrown in an I6 sounds unbelievably fiercer than this one in the video. I towed it home and it is getting all kinds of parts thrown on to get it roadworthy.
