Are you thinking of replaceing the stock silencer,
with the FMF silencer factory 4.1?

Not at this point because of simply spending another 3-400 on exhaust doesn't really get me too fired up at this point. Maybe later, but for the time being I'm basically satisfied with what I've got.

I too just installed a PC t-i system & noticed a little more on bottom...not near the effect the PC system had on my 04 YZ or 06 CRF though.
