hi
I'm ready for exhaust. I have 69 coronet with a approx 500 hp 600 ft lb. 440. Doug's headers. I saw frieburgers hot rod garage about 3" vs 2.5". My exhaust guy doesn't wanna do up and over the rear axle with 3". I was thinking 2.5" from headers back with y's and block off plates. That way I can gain that 10 hp loss from using 2.5" vs the 3" with uncorked headers basically. And 2.5 is cheaper and easier to work with. Looking for insight.
