99 yz400f exhaust

ive got a 99 yz400f with the white bros e-series muffler on it. i cant stand it, the stinking thing is so loud and obnoxious. my question is... does anyone have any suggestions for a quieter muffler or maybe there is another bike out there that has a better selection of mufflers that would interchange with mine?

Can you get a spark arrestor insert for it? that might be a quick way to "fix" the noise problem

its got the plate in the end of it and it exhausts out of the baffles around it
