Fmf 4.1 exhaust question

3 posts in this topic

This might be a stupid question, but I'm trying to get a spark arrestor for my 2005 yz450f. It has an FMF factory 4.1 exhaust on it, and I need to know if it is an r.c.t or not. Are the arrestor's different between a regular one and an r.c.t? I have seen a different one online. Thanks for the advice

Yes I'm pretty sure the rct is the new stuff they are pushing and it goes in with a snap ring. Yours is the regular 4.1 spark arrestor and takes a allen bolt.
