Trail Legal Aftermarket Full Exhaust?

There are a lot of exhaust threads on this forum, but I can’t find a post that answers this specifically…

Are there any aftermarket "full" systems that are under 96db and provide a worth while performance increase?

I am not a sound guy, and don’t really care about the note.

I am looking to add as much "bolt on" trail performance as possible.

I will be adding a clutch kit that favors low end acceleration performance even if I lose top end speed (I don’t need to go quite 85 mph on the trail anyway)

I am thinking of a PCV plus autotune and a full exhaust (but needs to be trail legal in Wisconsin. (96 decibels when measured on the “A” scale)

I appreciate any sugesstions
