Hi guys this should be easy I have a 73 impala with a 383sbc 350-375hrs/ 400fbls of torque. My car has 2 inch pipes,would this be to little back pressure or to much; I was going to run straight pipe with no mufflers on my 2 inch pipes.I have headers on it to with 3inch collectors. Like to no what u think thanks. and if the 2inch would work should I add a cross pipe?
I say 2.25” smallest on a v8 no matter what size. Any smaller causes too much back pressure and weird sound. For your 383 i'd get 2.5".
