Alright guys, I have 2 2005 yz125's, on one of them I have a FMF SST pipe with the titanium 2 silencer, and on the other one I have a stock pipe with the FMF turbinecore silencer. I have come to realize that the full FMF system really mellows down the bottom end, while the bike with the stock pipe has way more pull out of corners. So I want to try the FMF SST pipe with a stock silencer to see if that will make a difference. Does anyone know if the stock silencer will fit into the pipe?
