there are actualy two baffle plates in these mufflers, I removed the rear one, once i removed the tailpipe inner housing, and there is one in even further, there are lots of info and pics here on this subject. I removed one baffle and put on pro moto billet and it sounds ok, with everything out i guess it would sound closer to a YZ.... jet up and you should be good to go

Once you remove one or two of the baffles, do you know what kind of horsepower gain is achieved? Will I notice any horsepower gain? I just got my bike and I'm still breaking it in. -Should be officially through my first tank of gas this weekend. :applause:

Here is a recent thread that talks about this. There are also links to older threads that have pics of the internals.
Start with the first plate and try it out... Will prob be real loud with none.
