Muffler-inexpensive mods to resemble sound of bolt ons
Well folks, thanks for all of the replies. I did the 3/4 inch core drill first, which sounded good. The immediate thing I noticed is it's like pulling the cork out of your dirt bike muffler you put in when washing the bike.... THEN forget to pull it out when trying to start it. It will run, but much better with the cork removed. I think the core drill approach more resembles or mimics the aftermarket pipe design in the airflow department more so than the small drilled holes in the internal end cap. Sort of reminds me of the road king before and after putting the mid range cams in.
More MPG that someone mentioned..... well, have not check that part out yet, but more free flowing exhaust would tend to make me think it would help the mpg.
Just my thoughts.
I guess also, what I have read on all of the can instructions is that the maps do not require fatting up, they do this sort of automatically matching increased fuel delivery with increased air flow, resulting in more torque/hp.
