1 3/4 Header & Dual 2.5 Cutouts Vs. 1 7/8 Header & TSP TD Dynomax I was wanting to know how much of a difference in horsepower, if any, will going from dual 2.5 cutouts after the 1 3/4 primary BBK headers and BBK Y pipe to a 1 7/8 header w/ Texas speed true dual system using the Dynomax muffler. This will be on a h/c motor with a cam with 17* of overlap.
