When To Change From 2 1/4 To 2 1/2 Exhaust
I changed my exhaust on my mustang from 21/4 to 2 1/2 before I did and motor modifications .I'm wondering now if I would be better off with the 2 1/4 at least at the floe tube area since we know the 5.0 need's a lttle back pressure.Anyone have any comment s on this ?Thanks
