Icebox Dyno at Comptech

Forgive if this has been posted already. This is the first I've seen of it. Looks like max 6 HP increase on top of header and exhaust gains. FYI

dyno graphs look pretty good, some low-end torque loss, but not much, and some strong high rpm gains. The other promising thing about these graphs is that they only used an axel-back exhaust. So there is more to be gained with a full cat-back and midpipe.
