How do i quieten my exhaust

04 wr450 with white bros can, tried reducing number of baffles, seems to make no difference.

Is there a mod or something to replace the bolt on end plate part ?

used for green laning, seems to be the loudest in the group

If you have a e-series White Bros makes a quiet core insert. It helps some but that muffler tends to always be on the loud side when you pin it.
