It should be close. You may need the smaller diameter end piece or whatever it comes with in though. I would think it should be fine.

I have an 04 w/ a curtis pipe. Will it be OK if I went to Hatfield McCoy trails?

The sound limit is for a race and they are making all of us go through tech inspection so hopefully I can pass

I have the white brothers carbon pro II and I think it has a sound rating of around 104db... dont quote me on that and I am not sure if it has the same rating as the one you have... but I know that they caught me at the dunes.... I dont know how to tone it down either....

Ended up passing with a 98 decibals and I had the big opennig in but the packing is still pretty new so that might have helped. Fire fighter I think they also make the smaller tips for the carbon pros also that might get you a little quiter
