Our limit is 40%, I scored an 8, it's just another fee basically, I don't see how anyone here could fail with a decent running rig that's stock or with a stock setting on a chip. Find out what you'll be measured by, and then you can make sure your rig complies.
Be aware, Idaho and Oregon both have VISUAL checks as well, YOU HAVE a CAT and a Muffler... You would likely pass without it, but the visual is still a requirement.
