I am thinking about adding an electric exhaust cutout to my 2.5 inch piping. I would probably do a 3 inch O2, Down pipe and whatever other 3 inch piping needed up to the cutout. Then leave the existing 2.5 inch piping the rest of the way. I assume it would give me the same power as a full 3 inch exhaust while open and Still sound reasonable when closed. I‘m guessing a full 3 inch will be loud all the time And maybe cost more. Any thoughts?
