i am trying to get a little more precise estimation of what kind of power i have. the dyno program i have is gm desktop dyno. i have glenwood logs on my small block right now. what style should i use for the exhaust catagory? it gives me stock manifolds, with and without mufflers, h.p. manifolds, with and without mufflers, small tube headers, with and without mufflers, and large tube headers, with and without mufflers.
